INTRODUCTION

1.1

General Banyu Urip is an oil and gas field located in the Cepu Block in Central Java, Indonesia. The expected peak production is 185 kbpd (165 kbpd annual averages) of sour crude and associated gas from four well pads. The field development will involve conventional onshore oil and gas facilities (including well pads, Central Processing Facility (CPF), flow line, water disposal and gas injection) and an export pipeline to transport processed crude oil to a Floating, Storage and Offloading (FSO) facility. The crude oil will be sweetened in CPF and sent via onshore and offshore pipelines to a FSO vessel located 23 km off of the north coast of Java near the city of Tuban. JP Kenny has been appointed to update the original 2001 Front End Engineering Design (FEED) for onshore and offshore export pipelines and develop Front End Execution Plan (FEEP).

1.2

Scope of Document The scope of this document is to present a conceptual construction execution strategy for installation of the proposed 71 Km of 20-inch onshore thermally insulated pipeline from kilometer post Kp. 0.00 to Kp. 71.483. This Onshore Construction Execution Plan should be read in close cooperation with the attached crossing list (Appendix A), which, amongst other details, specifies chainage versus construction method. It also species how each road, river, ditch, etc. will be crossed and refers to a typical construction drawing for each type of crossing. Hence specific construction methods are not discussed in this document.

1.6

Construction methods For this document several construction methods have been assumed: Conventional construction:

Construction on relatively dry land where normal pipe lay equipment such as standard side booms can be used. Stringing of pipeline will be performed ahead of the main line welding spread. The main line welding spread will move ahead while trenching and burial is progressing at the same pace as construction of pipeline. The trench will not be open for more or longer than necessary. If water is present in the trench it will be disposed of by using pumps prior to lowering the pipe (dry trench method)

Wetland construction:

This is the area where it is too wet to use normal pipe lay equipment but not wet enough to do push pull. In this area special wetland equipment may be used, such as swamp backhoes, in combination with a roller system to push the pipe along the terrain.

Push-pull construction:

Construction technique in relatively wet areas. Here the welding station is stationary and pipeline is pushed out (floating) inside the water filled pre-dug trench, hence no stringing is required. It is guided at the end by an (swamp) excavator. Once a pre determined length has been welded and pushed/ pulled into the trench, the trench will be pumped dry allowing the pipe to settle on the bottom. Then, the trench will be backfilled.

HDD:

Horizontal Directional Drilling will be used in those cases where conventional construction is deemed impractical, too costly or otherwise unfeasible.

2.0

FIELD LAYOUT The Banyu Urip export pipeline consists of one 20” onshore thermally insulated pipeline of approximately 71 km long from CPF to the Palang shore crossing. The onshore survey is being finalized and the preliminary export pipeline layout is presented in Figure 2.1.

Figure 2.1 Export Pipeline Route Based on 2006 Survey

BANYU URIP PROJECT



3.0

SAFETY, HEALTH, ENVIRONMENTAL, SECURITY QUALITY

3.1

Safety The concept “Safety is the concern of everybody involved” will be widely promoted. The safety on the sites will be championed by front line supervisors and will be strictly monitored by construction contractor HSES officers. It is recommended that the usual safety incentive programs are implemented and that Safety supervision on site will be in the order of 1 HSES officer against 20-25 workers. From Company side there will be HSES supervisors too, working close together with the construction contractors HSES officers. Additionally, it will be essential to have EPC contractor management committed to safety.

3.2

Health Health on the sites will also be monitored by the HSES officer in cooperation with the construction contractor doctor. All personnel involved in the project will be submitted to a medical check-up prior to employment. The temporary camps (if any) and/ or local accommodation will be inspected by construction contractor doctor, HSES officer and Company HSES representative before authorization for usage is given. Subsequently weekly HSES checks will be performed by construction contractor HSES officers. A monthly check and/ or random checks will be carried out by Company HSES representative on site.

3.3

Environment All environmental issues will be monitored by a construction contractor Environmental Specialist, it is anticipated that one such specialist will be employed to cover multiple sites. This function is a “stand alone” function and the Environmental Specialist shall not spend part of his/ her time fulfilling other functions. The Environmental Specialist will be responsible that the recommendations made in the AMDAL and any other project documents related to the environment are followed and executed to the full satisfaction of Company. A key document used to achieve this will be the Contractor’s Environmental Management Plan. An aerial photographic survey will be performed before and after completion of project activities, this will be required to monitor and access the impact of project activities during construction. It will also serve to show that construction contractor has restored the ROW to its original condition.

3.4

Security Security on the sites and camps will be provided by dedicated and trained Security officers, locally referred to as “Satpam”. These officers will be in charge of the security around the worksites, pipe lay down areas, warehouse(s) and/ or temporary camps. It is envisaged that personnel for security will be locally recruited. However, it should be noted that the use of locally recruited personnel for security tasks may lead to problems, please see section 26.

3.5

Emergency Response Plan The construction contractor shall develop an Emergency Response Plan (ERP) which will contain precise procedures to be followed for medical and security emergencies, flow charts of action to be taken and parties involved (with contact number) in case of emergency. The interface parties will be Company, construction contractor, security authority (police, fire fighting, etc), local hospital, transportation service (helicopter, ambulance, etc) depending on the type of emergency.

BANYU URIP PROJECT



3.6

Emergency Evacuation Plan As part of the ERP, the construction contractor shall develop his own Emergency Evacuation Plan (EEP) which will contain precise procedures to be followed for medical and security evacuations, usually in the form of flow charts of action to be taken and parties involved (with contact number) in case of emergency. The interface parties will be Company, construction contractor, security authority (police, fire fighting, etc), local hospital, transportation service (helicopter, ambulance, etc) depend on the type of emergency. The EEP will then be coupled to Company’s EEP by a bridging document, also prepared by the construction contractor.

COMPANY SCOPE OF WORK

4.1

ROW From the start of the project, Company has been surveying the proposed ROW and compiled a long list of land owners. Upon finalization of the pipeline route, negotiations with those land owners that are affected by the ROW will begin and shall be completed before the ROW is handed over to the construction contractor.

4.2

Procurement and supply of LLI During the FEED for the BU project, The FEED Contractor has identified the list of Long Lead Items. This list of items will be procured by Company and supplied to construction contractor. The main items on this list are the line pipe and valves. Delivery and collection points will be specified in a later stage.

BANYU URIP PROJECT



5.0

INTERFACES

5.1

Pipe coating The pipeline has been designed with a thermally insulated cover. Pipe coating is a very specialized process and coating will most likely be done by a coating company in Batam or Bintan, Indonesia.

5.2

Pipe delivery The present strategy by Company is that the onshore construction contractor will collect the pipe at the coating yard. The construction contractor will take receipt of the coated pipe at the coating yard and will organize transport to site.

5.3

Valves Valves may be purchased by Company if considered Long Lead Items. If so, only purchasing will be done by Company, shipping of the valves to the nearest practical port, importation into Indonesia and transport to the site will be the responsibility of the construction contractor. For the valve stations, the construction contractor will have to pull the cable from instrument and electrical equipment to the communication building and to PLN power lines, after obtaining PLN permission. The connection of the cables inside the communication building and the installation of the telecommunication equipment will be performed by the EPC1 contractor.

5.4

Offshore contractor It is of utmost importance that good coordination between onshore and offshore contractors is established and maintained throughout the project. Regular interface meetings will be scheduled, with their frequency increasing as activities increase. Both construction contractors shall coordinate in such a way that the tie-in between onshore and offshore pipeline shall not result in any delay to either party. Company will attend the interface meetings but coordination of activities shall be construction contractor’s responsibility.

5.5

CPF contractor Similar to the above, good coordination will be required between the onshore pipeline construction contractor and the CPF contractor. Regular interface meetings will be scheduled, with their frequency increasing as activities increase. Both contractors shall coordinate in such a way that the tie-in between the onshore pipeline and CPF shall not delay either party. Company will attend the interface meetings but coordination of activities is construction contractor’s responsibility.

5.6

Shore Approach The shore approach design and construction up to offshore/onshore tie-in point (landfall point) is included in offshore scope of work and will be performed by either Pre-Trenching and/or Horizontal Directional Drilling (HDD). Therefore, the onshore construction contractor should leave his part of the work scope in such a way that the offshore construction contractor will be able to perform the shore approach section and tie-in between the two sections without delays to his operation. For this purpose regular interface meetings shall be organized between the onshore and offshore construction contractors, (see section 5.4).

BANYU URIP PROJECT



5.7

Local authorities It will be unavoidable that construction contractors come in contact with local authorities, especially for the application of permits. All permits required for the (preparation of) construction work will be organized and applied for by the construction contractor.

5.8

Local population The construction contractor shall pay great attention to maintain the harmony with the local population. For this purpose construction activities around densely populated areas should be restricted as much as possible. Wherever possible, construction contractor shall do his best effort to employ locally available personnel. After completion of the work and after the restoration of temporary access roads, pipe lay down areas, camp facilities etc. has been completed the construction contractor shall obtain Land Owner Sign-off certificates to avoid potential future claims. These certificates will be handed over to Company for filing and future reference.

5.9

Worthiness Certification of the Work (SKKP) At the end of construction, during the pre commissioning stages of the work, the construction contractor shall be responsible for obtaining the worthiness certificate (SKKP), issued by MIGAS, for government approval of the export pipeline system. The inspection for certification is usually conducted by a MIGAS approved 3 rd party, whereby MIGAS acts as a witness. If MIGAS indeed elects to use 3rd party for the inspection, construction contractor shall make contractual provision for obtaining the inspection service from the 3 rd party approved by MIGAS as stipulated in Appendix H of the Contract (refer to document number IDBU-ED-QSPDS-000006, Upstream Project Quality Assurance – General Requirements, Rev. C)

BANYU URIP PROJECT



6.0

MOBILIZATION Due to the intricate route of the pipeline (dry area, wet area, HDD, road/ river crossings, tie in, etc.), limited amount of roads available and the fact that the route traverses through densely populated areas careful mobilization of personnel and equipment is of vital importance. The construction contractor shall prepare his mobilization schedule taking in account all the previously mentioned issues and ensure that enough time is planned so that personnel, equipment and material will arrive in time at the correct work location for each specific activity as described in section 7.0 Workforce, Accommodation, and Transportation.

BANYU URIP PROJECT

7.0

WORKFORCE, ACCOMMODATION AND TRANSPORTATION

7.1

Workforce Where ever possible the contractor shall use locally recruited personnel which, shall be trained in safety issues in order to fulfil their tasks (see section 7.3). It is anticipated that unskilled labour will make up a large part of the work force. The skilled part of the labour, such as Supervisors, welders, NDT specialists and the like will most likely brought in by the construction contractor and accommodated in the temporary camp. The direct versus indirect costs are extensively discussed in the EBM (Estimate Basis Memorandum). The work will be executed with one mainline spread, one mini mainline spread and several smaller specialist spreads as per tabulations below:

7.1.1

Infrastructure preparation and renovation spread This team will perform early preparation work such as the upgrading and/ or widening of roads, preparation of Lay Down areas, construction of temporary camp, preparation of push pull platforms, etc. After completion of preparation work it might be restructured as a ROW and clearing spread. Later it will be used to the renovation work on any roads, if required. Preparation work for access and lay down areas are identified in the Pipe and Equipment Transport report referred to in section 1.4. The make of this team is such that it can easily be split up in 2 separate teams working independently on different locations. Equipment

Total 4 4 4 2 2 2 24 42

Note: This is due to the fact that the equipment and manpower columns were not meant to be aligned.

7.1.2

ROW clearing and grading spread This is a medium sized spread that will move ahead of the main line welding spread and “clear the way”. It is mainly made up of local workers who will have had safety induction and have been provided with the appropriate PPE. An excavator has been added to this spread for grading and to make access bunds for workers as and where necessary.

Accommodation The contractor questionnaire workshop did not give a clear indication about this issue but in this study it will be assumed that at least one temporary camp will be erected along the pipeline route. The assumption will be that the camp will be erected in the area near LD 08 (Kp.29.575), located at the HDD entry point of the Solo River HDD.

This location is centralized yet slightly outside a major city (Bojonegoro) to which it has easy access. The Kp. location in relation to the pipeline is approximately Kp.29.500. There appears to be ample space alongside the road for temporary camp erection. The size of the camp should be sufficient to accommodate approximately 175-200 personnel. Adjacent to the camp there will be a temporary fabrication yard and secure storage facility for selected Company supplied items (such as valves and E&I equipment).

7.3

Training As an ongoing part of HSE, construction contractor shall develop and maintain a training program to ensure that all construction contractor personnel are trained in accordance with the construction contractor’s HSE manual. Locally recruited unskilled personnel may be trained in simple tasks such as cleaning, banks man, office boy, laundry, basic security etc. The training program will be executed in such a way that it will not have any effect on the progress of the work.

7.4

Transportation The workforce that is accommodated in the camp will be shuttled to the work locations by bus and/ or light vehicles. The same transportation may be used to collect the local workforce that will stay accommodated in their private houses and that will gather on pre determined collection points. Transportation along the ROW may be done by 4WD vehicles, or buses.

TRANSPORTATION AND STAGING OF PIPE & COMPANY SUPPLIED ITEMS

8.1

Transportation and staging of pipe Once the pipe has arrived in the nearest practical port it will be offloaded and loaded onto the transportation trucks (subcontractor of construction contractor). These trucks will distribute the pipe along the pipeline route to pre determined and prepared lay down areas (LD). Transport management process and procedures for safe transport of pipe need to be developed as the pipe will be transported through congested and populated area. Once the trucks arrive at the lay down area they will be offloaded and pipe stored in a correct manner. A QA/QC system shall be in place to assure that no damage to the pipe has occurred during transport and subsequent offloading, and if it has, to document and follow-up accordingly. The basis for the calculations concerning the space requirements for the lay down areas (LD) , has been that stacking of the pipe will not exceed 3 layers. The temporary lay down areas are located at the approximately Kp. positions mentioned below. Exact location and access routes can be found in the Pipe & Equipment Transportation Report referred to in the beginning of this document. Approximate amount of joints and storage area per laydown area:

Note: LD13 will only be used as a set up area for the HDD equipment. Transport of pipe and equipment should be limited as much as possible as to reduce impact on residents.

8.2

Transportation and storage of Company supplied items Similar to the pipe, once these items have arrived in Surabaya or Jakarta they will be offloaded and loaded onto the transportation trucks (subcontractor of construction contractor). These trucks will transport the items (such as valves) over the public roads towards the temporary camp for temporary storage. Once the trucks arrive at the storage area they will be offloaded and items stored in a correct manner. A QA/QC system shall be in place to assure that no damage to the items has occurred during transport and subsequent offloading.

RECOMMENDED CONSTRUCTION METHODS

9.1

Basis for recommended construction methods The proposed construction methods for the installation of the proposed 71 Km of 20-inch onshore thermally insulated pipeline are based on the following:

9.2



Route illustrated on Topographic map.



Alignments sheets



Survey & geotechnical reports provided by Company



Satellite imaginary



Site visits



Feedback obtained from Onshore Contractor Questionnaire & workshops



Local experienced construction personnel



Independent consultants



Pipe and equipment transportation Report

Assumed construction methodologies For this Plan Contractor has assumed that conventional onshore pipeline construction (I.e. the use of one mainline spread using several side booms, welding, trenching and burying as the spread moves along the pipeline route) will be the preferred option of the construction contractor. Several smaller specialist spreads such as a mini mainline spread, tie-in spread, bored crossings spread, HDD spread & hydro test spread will support the activities and work ahead and/ or in parallel with the main pipeline spread. The Plan also assumes that the construction contractor will start near the CPF area and work his way towards Palang. However, should the construction contractor decide on a different approach (i.e. due to weather conditions) the segmentation built into the plan will allow for easy adjustment either way. Preparation of ROW, grading, clearing & stringing will have preceded the start of the mainline welding activities. The MLWS will move along the ROW and weld the pre-strung pipe. Initially, a trench will be excavated and the first 100 meter of pipe lowered into it after welding, NDT and coating. The spread will then move ahead as a train: excavators in front to excavate the trench, welders/ NDT team and coaters to fabricate the pipe, side booms in the middle to lower the pipe and excavators at the end to backfill after pipe has been lowered into the trench. Part of the pipeline route will traverse through relatively wet areas and in such areas it is expected that the construction contractors will either switch to a push pull method and/or start using equipment that is more suitable for this kind of environments. For estimation purposes, the expected daily productivity rate of 500 meter per day will drop by 40% to 300 meter per day. In this Plan, this type of

BANYU URIP PROJECT




Rev 0 Page 26 of 52 construction has been named push pull or wetland construction. In these areas temporary stationary welding platforms will be erected and pipe pushed-pulled into a pre excavated and flooded trench.

Limestone: It has been noted that limestone outcrops exist along the pipeline route, the table below is extracted from the 2007 Geotechnical report and indicates the boring location versus the chainage in the crossing list: Bore hole number

The Report on Geotechnical Review of Pipeline Route, CPF and FPSO (IDBU-IB-GBSIT-000001) states that the limestone encountered along the route is of a “fresh limestone consistency” with a site classification of SD (stiff soil). For estimation purposes rock breaking equipment has been incorporated in the equipment list for the Main Line Welding Spread but it is strongly recommended that construction contractor should make his own assessment of the impact limestone will have on his construction schedule. For this particular Plan it has been assumed that the limestone deposits will not have a significant effect on the schedule.

Pre commissioning: For purposes of this Plan it has been assumed that each pipeline section (including the HDD strings) will be separately cleaned, brushed, flushed, gauged and hydro tested by the hydro test team. Normally, once two adjacent sections have been completed the valve will be installed and welded in place with 2 Golden Welds. In such cases where the valve position is to be installed below the local ground water level, the temporary pit will be kept dry by the use of pumps until such a time that the tie-in has been completed. Then upon completion of the installation of the last valve, the pipeline will be de-watered, dried, capped and inerted by Nitrogen.

Cathodic protection Anode beds will be installed along the pipeline route by the spreads that are deployed at that particular time to avoid having to go back along the complete pipeline route. It is of vital importance that anode beds will be available prior to start of pipeline installation activities.

Construction challenges Approximately 64 kilometer of the pipeline route traverses through paddy fields and/or cultivated land. In addition there are 13 main road crossings, 53 village road crossings, 6 track/ footpath crossings, 1 operational railway crossing, 20 river crossings, 15 watercourse crossings (creek or stream), 84 irrigation ditch crossings, 8 pipeline crossings, 1 buried cable crossing, 1 buried fiber optic cable crossing and 2 main river crossings (Kalitidu River and Bengawan Solo River). Five major construction challenges have been identified: 1.

To have all pre construction activities (such as preparation of lay down areas, temporary access roads, reinforcement of bridges, widening of roads, temporary camp, recruitment of personnel, permit application, etc.) completed in the 6 months after contract award and before start of pipeline construction activities.

2.

To obtain access to and transfer equipment, material and personnel along the ROW under difficult conditions

3.

To perform road crossings with the least disruption to local traffic as possible

4. To complete the pipeline route in the timeframe set by Company and partially during wet season. 5.

To keep all working areas (especially trenches) safe for and from the local population

The major pipeline sections and construction methods for the pipeline are presented in the table below. Specific construction execution methods are detailed in the Project Crossing Matrix, included as Attachment A of this document.

Tabulated Construction Methods Legend Light green – Conventional construction using tracked side booms Light yellow – Horizontal Directional drilling Light blue

ONSHORE PIPELINE BUOYANCY CONTROL In order to keep the pipeline in place during installation, buoyancy control is required when the pipeline route crosses free standing or flowing water (such as a river crossing). For this Plan, the method selected to control this buoyancy is continuous concrete coating but the construction contractor might opt for another stabilization technique such as concrete saddles. The areas that potentially need concrete coating along the export pipeline route are rice paddy fields (that cannot be dewatered) and waterway crossings. Concrete coating is not required in paddy field areas where the trench can be pumped during installation. Waterway crossings and all areas where a “wet” installation is anticipated require concrete coated pipe (refer to alignment sheets).

BANYU URIP PROJECT




19 Feb. 2008 Rev 0 Page 31 of 52

River crossings that utilise the HDD construction technique do not require concrete coating because the HDD construction technique is a trench less type construction method that contains the pipeline within a drilled hole that has a cover depth greater than the minimum required 1.2 m.

CONSTRUCTION EXECUTION STRATEGY OVERVIEW The construction strategy for the installation of 71 Km of 20-inch thermally insulated pipe is based on the route illustrated on the Pipeline Alignment Sheets (49 Sheets) and references mentioned in section 9.1. The majority of the pipeline will be installed using conventional onshore pipeline construction; however, some sections are installed by HDD and others maybe installed using push pull technique and/ or equipment suited for wet areas.

10.1

Kp. 0.000 to Kp. 7.497 The 1st segment is from the Pig Launcher site at CPF to the entry point of HDD No.1. The pipe will be installed using conventional onshore pipeline installation through paddy fields, a few creeks, power cable, a river, and two gravel MCL roads.

10.2

Kp. 7.497 to Kp. 8.072 The 2nd segment is a Horizontal Directional Drill under a village road and the Kalitidu river

10.3

Kp. 8.072 to Kp.24.153 The 3rd segment is from the exit point of HDD No.1 to entry point of HDD No.2. The pipe will be installed using conventional onshore pipeline installation through paddy fields, gravel roads, ditches, district roads and a river.

10.4

Kp.24.153 to Kp.24.558 The 4th segment is a HDD under an operational railway and Provincial road.

10.5

Kp. 24.558 to Kp.29.898 The 5th segment is from the exit point of HDD No.2 towards the entry point of HDD No.3. It includes the VS-E2. This area is relatively low and passes by the Petrochina facility, the construction contractor might choose to use push pull construction technique here.

10.6

Kp.29.898 to Kp.30.325 The 6th segment is a HDD under the Bengawan Solo River

10.7

Kp.30.325 to Kp.38.888 The 7th segment is from the exit point of HDD No.3 to a Provincial road crossing. This area is relatively high and conventional onshore pipeline installation through paddy fields, ditches, village roads and a river.

10.8

Kp.38.888 to Kp.49.000 The 8th segment is from the Provincial road through the low lying area at the flood protection dyke and up again to higher ground around Kp.49.000. This is the wettest area along the pipeline route and push pull technique and/ or wet land construction methods are likely to be used here. The area consists mainly of paddy fields and irrigation ditches.

BANYU URIP PROJECT



10.9

Kp.49.000 to Kp.69.653 The 9th segment is from the higher ground towards the village (congested area near the coast). It also includes the check valve station VS-E4 and valve station VS-E5. The pipe will be installed using conventional onshore pipeline installation through paddy fields, gravel roads, ditches, district roads and forested areas.

10.10

Kp.69.653 to Kp.70.399 The 10th segment is a congested area around Banjaranyar village. A small spread will be used here as the pipeline route snakes through a village. Productivity in this area might drop by 50%.

10.11

Kp.70.399 to Kp.71.472 The 11th and last segment is from the edge of the village and ends at the shore approach. It traverses through paddy fields, village roads, irrigation ditches, unused shrimp ponds and the main Provincial road from Tuban to Gresik.

KP.0.000 TO KP.7.947 CONSTRUCTION PLAN The mainline welding spread (MLWS) will be mobilized via ACS 22B and incursion will start from LD 15 towards CPF. Then the spread will turn around and proceed towards the East (Note: the tie-in between the onshore pipeline and CPF will be performed by the CPF construction contractor). As this is relatively high ground the pipeline construction will be done by conventional method. Any roads, rivers, ditches, etc. will be crossed as indicated on the alignment sheets and crossing matrix. Temporary bypasses will be constructed during the preparation phase at ACS 22A & 22B, ACS 21. Meanwhile the HDD spread will be mobilized to HDD entry point No.1 via ACS 21. LD 13 will be used to stage and prepare the HDD drilling pad. 4 weeks before the mobilization of the HDD spread the mini mainline welding spread (MMWS) will be mobilized to the area after the exit point of HDD No.1 (Kp.8.072). The mini mainline welding spread will be mobilized via ACS 22A. It will proceed to the exit point by incursion into the ROW at LD 12 and start fabricating the HDD string. Once the HDD string is completed it will be pre-tested. Once the pre test on the HDD string has been completed, the mini mainline welding spread will move to the next HDD exit point location (Kp.24.558) Upon completion of reaming, the prepared HDD string will be pulled in the hole. Once the pull has been completed the pipe will again be tested. Upon successful hydro testing, the HDD spread will be demobilized to the next HDD entry point at Kp.24.153. By this time the mainline welding spread will have reached the HDD entry No.1 and will perform the tie-in between mainline pipe and HDD. Once that is completed the MLWS will be transported out by ACS 21 and back into the ROW by ACS 20A.

11.1

Temporary workspace & access Access Roads: ACS 21, 22, ACS 22A & ACS 22B (MCL Roads) to transport pipe. Temporary workspace is located at: KP 0.843 (LD15) : On the ROW next to MCL gravel road KP 1.472 (LD 14) : On the ROW next to MCL gravel road KP 7.565 (LD 13) : On the ROW (No stacking here as to minimize disturbance to residential area Kalitidu).

BANYU URIP PROJECT



12.0

KP.7.497 TO KP.8.072 CONSTRUCTION PLAN This is a HDD under a village road and Kalitidu river. The HDD spread will be mobilized via ACS 21. The drill pad will have been prepared during the preparation period before the actual start of project. As mentioned in section 11.0, the mini mainline welding spread will have prepared the HDD string, ready to be pulled into the hole. On completion of the hydro testing activities, the HDD spread will be demobilized via ACS 21 and move to the next drilling location (see section 13)

12.1

Temporary workspace & access Access Road: ACS 21 Temporary workspace is located at LD 13. Note that the bridge encountered on ACS 21, nearest to the HDD entry point, will have to be reinforced.

13.0

KP.8.072 TO KP.24.153 CONSTRUCTION PLAN After completion of the tie-in between mainline pipe and HDD entry point at HDD No.1, the MLWS will be mobilized via ACS 20A. Where ACS 20A crosses the ROW the MLWS will proceed into the ROW going West towards the exit point of HDD No.1. Once it has arrived there (and to avoid the mobilization of the tie-in spread to this point) it will tie in with the HDD string and resume conventional laying operation back towards LD 12. As this is relatively high ground the pipeline construction will be done by conventional method. Any roads, rivers, ditches, etc. will be crossed as indicated on the alignment sheets and crossing matrix. Temporary bypass will be constructed during the preparation phase at ACS 20A, ACS 19 & ACS18. Prior to the arrival of the MLWS, the tie-in spread will have prepared the area for VS-E1. Now, the MLWS continues its way Eastwards. Meanwhile the hydro test spread will clean and test the complete section between HDD exit #1 towards Kp.0.000 and later HDD exit #1 towards VS-E1. After preparation for installation of the valve (VS-E1) and related civil activities, the tie in spread will move to its next location, namely the tie in between mainline pipe and HDD at HDD entry #2. VS-E1 will be installed later, once the section between VS-E1 and VS-E2 has been cleaned and hydro tested. The 2 major road crossings will be encountered at Kp.20.430 (RDX 02) and Kp.21.778 (RDX03) bypasses will have been constructed here during the preparation period. The MLWS will continue following the ROW up to the HDD entry point of HDD No.2, once arrived there, it will be loaded onto trucks and transported to LD 07 (Kp.32.456) via ACS14, see section 16.

Phone and power cables will have been re-routed and temporary access road constructed leading from the Provincial road (over the railway) and to the HDD entry point. The HDD spread will be mobilized via ACS 17 during night time hours. The drill pad will have been prepared during the preparation period before the actual start of project. After the mini welding spread completed the work for HDD string #1, it moved away and prepared the string for HDD #2. Mobilization of this spread was done via ACS 16 and incursion into ROW towards the HDD exit point at Kp.24.558. The same spread would have installed the section from LD 09 to the HDD exit. After the drill and successful post pull hydro testing, the tie-in spread will standby to make the tie-in between the HDD entry #2 and the main line. Once the tie-in is completed, the spread will move to the tie in between main line and HDD entry #3 (see section 15). Meanwhile, hydro test team will clean and test from HDD entry #2 towards VS-E1, Valve E1 can then be installed. Later, the hydro test team will clean and test from HDD entry #2 towards HDD entry #3.

KP 24.558 TO KP 29.898 CONSTRUCTION PLAN This section is located in a relatively low area and the construction contractor might choose to use push pull technique or wet land construction here. Whatever happens, it is likely that daily productivity here will drop by 30%. The mini mainline welding spread will have moved here after completion around HDD exit #1 and will fabricate both the paddy string and the HDD string for HDD No.2. It will first do an incursion from LD 09 towards the HDD exit point and then turn around. Once back at LD 09, it will cross the road and continue towards the North, pass the Petrochina well pad and up to the road (RDX 05) which will be crossed by open cut. A temporary bypass will have to have been constructed during the preparation phase. After that, the mini mainline welding spread will continue towards valve station VS-E2 (Kp.29.686). The valve location will be prepared and civil work completed. Then the spread will move on to Kp. 29.898, where the HDD entry for HDD #3 is located. Once reaching this point, the cleaning and hydro testing of HDD entry #2 towards VS-E2 can be performed. After completion the tie-in between HDD entry #2 and main line can be made. The hydro team spread then moves towards the HDD entry #3.

KP 29.898 TO KP 30.325 CONSTRUCTION PLAN This is a HDD under the Bengawan Solo River. The HDD spread will be mobilized here after the completion of the Railway and Provincial road crossing. During the preparation phase, preparations will have been conducted to prepare the drilling pad. The HDD spread will be mobilized from the district road over the ROW, a temporary access road will have been constructed here After the mini welding spread completed the work for HDD string #2, it moved away and prepared the string for HDD #3. Mobilization of this spread was done via ACS 14 and incursion into ROW towards the HDD exit point at Kp.30.325. The string will be prepared and pre-tested. The tie-in between HDD entry #3 and main line will be performed last, so that water from the Bengawan Solo River can be used to clean and hydro test all sections north of the Bengawan Solo River. Once the drill has been completed the pipe will again be hydro tested, after which a manifold will be installed to pump the water into the next section (VS-E3 to VS-E4)

KP 30.325 TO KP 38.888 CONSTRUCTION PLAN This section will start off with the HDD exit of HDD #3 and leads to valve location VS-E4. The pipeline follows relatively high ground mostly paddy fields, 2 district roads, some ditches, a river and a few village roads. The valve station location will be prepared by the tie-in spread. The main construction here will be conventional and performed by the MMWLS starting at the HDD exit and up to LD 07, after having completed the HDD string No.3. At LD 07 the MMWLS will be extracted and the section from LD 07 to Kp.38.888 will be performed by the MLWS, which will do an incursion into the ROW from LD 07 proceeding North. Once Kp.38.888 is reached the pipe need to cross a provincial road. A bypass will need to be constructed here, prior to arrival of MLWS. The cleaning of this section will be done pumping water from the HDD entry point #3 all the way up to VS-E4.

17.1

Temporary working space and access Access to HDD exit point #3 will be obtained via ACS 14 and following the ROW. Access to the North will also be via ACS 14 (towards Kp.38.888) and then by the ROW. (ACS 15 is not suitable for heavy equipment) Temporary workspace is located at: KP 32.456 (LD 07): On the ROW next to ACS 14 KP 38.888 (LD 06): On the ROW next to Provincial road from Bojonegoro to Tuban.

KP 38.888 TO KP 49.000 CONSTRUCTION PLAN Once the MLWS crosses the Provincial road from Bojonegoro to Tuban it will enter the start of the wettest section of the route, it will be entering the floodplain of the Bengawan Solo River. Construction for this area can start with conventional construction and later progress to possibly push pull or wetland construction. The route crosses the 8” Mudi pipeline at 39.950, a flood protection dyke at Kp.43.087 and then reaches higher ground again at around Kp.49.000. Cleaning of this section will again be done from HDD entry point #3.

KP 49.000 TO KP 71.472 CONSTRUCTION PLAN Once the MLWS spread reaches Kp.49.000 it will be coming onto higher ground again and encounter check valve station VS-E4. This valve station will have been prepared by the MMLWS after having completed the line from HDD exit #3 to ACS 14. Cleaning and hydro testing of this section will be done from HDD entry #3 towards VS-E4. After hydro test, a manifold will then be installed at the VS-E4 end, so in the future the water (which is in the pipe) can be pumped into the section from VS-E4 to the shoreline. Valve VS-E3 can now be installed. VS-E4 will be installed after cleaning and testing of the next section (VS-E4 to VS-E5). The MWLS will continue north where it will come across the next valve station, VS-E5 (Kp.51.768), located at the south side of the district road Regel to Tuban. This area also functions as LD 05. The valve station will be supplied with an access road to a small village road that is a branch of the Provincial road. This valve station will also have been prepared by the MMLWS spread before moving to VS-E4. Cleaning and hydro testing of the section VS-E4 to VS-E 5 will now be performed, by using water from the Bengawan Solo River. The valve VS-E4 can then be installed; this will ensure the water supply to the North of this valve. At the VS-E5 location a manifold will provide water from VS-E4 towards the shoreline. Upon reaching the district road, the road will crossed by open cut (RDX 09). A bypass will have been constructed here in preparation of this crossing. After having crossed the road, the MLWS will continue north. The tie in spread will move in and perform preparations for the tie-in work at VS-E5 and the road crossing. MMLWS will have completed work around VS-E4 and will have moved to Kp.67.792 where it will start conventional laying to the east of the district road and towards the congested (village area) The MLWS is now moving north towards Kp.55.587 where it will encounter the same district road again. Here however, the pipe will be tied in to the pre installed bored crossing (RDX 10) by the tiein team that has by now completed the tie-in at RDX 09. This bore will have been done in preparation and prior to arrival of the main MLWS. The bore crosses under the district road and 10” Petrochina pipeline. It must be noted here that the 2007 geotechnical survey indicated limestone deposits at -2.25 meter (CPT 25). Once the spread has moved to the opposite side of the road, it will continue conventional construction towards the north. The area constitutes mainly of paddy fields but limestone deposit has been encountered (see section 9.2). The tie-in spread will perform the tie-ins at the bored crossing at Kp.55.663 (RDX 10). Now the spread moves towards the Provincial road between Tuban and Surabaya (RDX11). This is a main road and therefore heavily trafficked. For this reason, the road will be crossed by a bore, which will have been completed prior to arrival of the MLWS. The MLWS will move across the road and is now entering a forestry area. It starts off with scattered trees and moves trough young forest towards the north. The construction will be done in the conventional way. The edge of the forest is at approximately Kp.62.365 where construction will encounter the start of a wet area again as the area starts coming nearer to the coast. The ground conditions change back again to paddy fields. The MLWS continues constructing to the north then at Kp.67.200 takes a turn to the right, passes LD 02 (67.886) and stops at the road. There the tie in will be made to that part of the line already installed by the MMLWS that started here earlier (after

completing the work at VS-E4). The tie in will be done by the tie-in spread, which by this time, will have completed work at the bored road crossing (RDX11). Note that limestone was encountered in this area, see section 9.2) The MLWS is demobilized at this point and shipped out to the North via the district road in front of LD02. (ACS 01A). The tie in spread will now join the MMLWS and work together through the congested area towards the Palang shore line. The congested area starts at Kp.69.653 where the construction contractor will have to go very carefully and slowly to weave the pipeline in between the local houses. Certain areas might have to be dug by hand and productivity will slow down significantly. Once out of the congestion at Kp.70.399 conventional construction may resume and will pass through paddy fields and unused shrimp ponds up to Kp.71.323. Here a Provincial (coastal) road is encountered from Tuban to Gresik. This road is heavily trafficked and a bored crossing will have been performed prior to arrival of the MMLWS (RDX 13). (Note that limestone was encountered in this area, see section 9.2). The MMLWS will then be demobilized. Now, the section between VS-E5 and VS-EP can be cleaned and hydro tested. After hydro test VSE5 can be installed. The work for the valve station VS-EP at the Palang shore line will be completed by the remaining units of the tie-in spread. This work consists of the installation of 2 valves and civil works such as a control building. Once VS-EP and related pipe have been installed it will be cleaned and hydro tested by using the water from the Bengawan solo River pumped via the pipe towards the shore. The final tie-in between onshore and offshore pipeline will be done by the offshore construction contractor.

19.1

Temporary working space and access Access to this part of the pipeline route will mainly be by following the ROW. On those places where the ROW crosses main roads lay down areas are staged and access possible via the main road. The ROW is criss-crossed by smaller village roads, which can be used for small vehicles. Temporary workspace is located at: KP 51.833 (LD 05): On the ROW next to District road from Bojonegoro to Tuban. KP 55.663 (LD 04): On the ROW next to District road from Bojonegoro to Tuban. KP 59.293 (LD 03): On the ROW next to Provincial road Tuban barat to Surabaya KP 67.886 (LD 02): On the ROW next to District road (ACS 01A) KP 71.421 (LD 01): On the ROW next to Provincial road Tuban to Gresik & Surabaya

PRE COMMISSIONING Pre commissioning of the pipeline sections will take place throughout the construction phase (see section 9.2), the final and/ or other pre commissioning activities will continue for approximately 2 months after mechanical completion.

21.1

Pipeline sections See section 9.2

21.2

Valves The valves will have been tested in the factory. Prior to and after the installation of the valves into the mainline, construction contractor’s pre commissioning team will test the valves for functionality. In case any problems are encountered the construction contractor will inform Company, who (as owner) will request vendor assistance. The expenses for such assistance (travel, accommodation, etc) are usually under responsibility of the construction contractor.

21.3

Electrical systems Once the electrical systems have been put in place and connected, construction contractor’s E&I team (Electricity and Instrumentation) will perform the testing of this system in accordance with approved ITP’s. The connection of the E&I and communication equipment to CPF facilities will be done by the EPC1 contractor when both systems are integrated. The cathodic protection system functionality will be tested in accordance with document number IDBE-WO-YSPDS-EN0003 “Cathodic Protection Requirements for Onshore Pipelines” (design requirements, site studies, cathodic protection method, monitoring, commissioning requirements and documentation).

21.4

Pipeline completion Once the final weld has been completed and accepted, the pipeline or parts thereof, will be filled with water, hydrotested, then de-watered, dried and inerted by Nitrogen as per Company specifications. This sequence is part of a separate procedure but is estimated to take place within a period of 4 weeks after mechanical completion of the line. The tie-in between onshore and offshore will be performed by using a “Golden Weld”.

24.1

Site management On the construction contractor side it is assumed that the work will be supervised by either expatriate or Third Country Nationals, except for those activities that require a relatively large amount of manual labour, such as clearing and grading & restoration & infra structure preparations. For Company it is recommended to have 1 CSR, Company Site Representative, (directly responsible to Project Manager), expatriate Superintendents for each working area (the pipeline route can be divided into 2 or 3 segments) and national supervisors, one for each working spread. In addition, the Superintendent will be assisted by a national safety supervisor. The national safety supervisor reports in tandem to his Superintendent and the Safety Superintendent. The overall QA/QC is to be supervised by an expatriate welding superintendent with a national welding supervisor attached to each spread where welding is performed. The welding superintendent reports to the Superintendent in charge of that particular area. Weekly site meetings will be held between the construction contractor and Company site personnel. Daily reports for each spread will be submitted by construction contractor and signed by the Company Superintendent.

RESTORATION AND RE-VEGETATION Prior to construction a survey will be done to identify environmental conditions along the ROW. It is highly recommended that aerial photography is used as to establish an environmental base line. During construction, the backfill and restoration spread will follow the main line welding spread return the surface of the land to its original condition. Care will be taken that the backfilled trench will be crowned as to avoid the creation of water channels. Final Survey will be done to check the restoration and vegetation.

LESSONS LEARNED From previous projects the following lessons are to be taken into consideration:  Long Lead Items are to be available before start of project (especially anode beds are not to be forgotten, this will avoid a lengthy and costly “anode installation campaign” after the main pipeline has been completed).  Good and experienced Company supervision is a must and should be mobilized in the early stages of the project.  Daily reports are crucial to counter any claims construction contractor might file.  Quality of the work will depend on the experience of the construction contractor and is directly related to the amount and quality of supervision by Company.  The Contract should be applied in the most stringent way; only then will the best possible result be obtained. However, certain leeway must be available to the judgement of the Superintendents.  Contractor installation procedures should be ready and APPROVED by Company before start of work on site.  A certain amount of days will certainly be lost due to the IDUL FITRI holiday  The backfilled trench needs to be “crowned” to allow for future settlement. If this is not done correctly a channel will be the result and water will start flowing over the pipeline. The creation of “borrow pits” should be strictly forbidden and the importation of additional soil to make up for any shortcoming clearly dictated in the contract. This is an item that is very often grossly underestimated by construction contractors resulting in endless discussions between construction contractor and Company at the end of the project.  The selection of security personnel must be done very carefully. Experience obtained during previous projects has shown that if security personnel are recruited from the same area where the work is performed they are ineffective in fulfilling their task in case of conflicts, as their residential status severely restricts their effectiveness. Likewise, bringing in a security (contractor) from outside the area will spark unrest as they will be seen to be “stealing” the work from the local people. A careful balancing act is usually the result.

From this project the lessons learned consist of:  There should have been one large sized map covering the complete pipeline route indicating terrain conditions.  A geotechnical engineer/ surveyor should have been part of the FEED team to analyze geotechnical reports and assist/ advise the FEEP personnel.
