P&ID’S DEVELOPMENT

The first Contractor’s duty is to verify the P&IDs included in the BEDP. The following items shall also be checked: • • • • • •

System operability Symbology for Project Specification Equipment configuration (No. of shells and type of exchangers, static equipment dimensions with elevation requirement and connecting nozzles, machineries and heater arrangement) Piping Information (line class and identification code, with class break point, utility connections for start-up and shutdown, line up of start-up and shutdown, piping arrangement special requirements) Instrument Information (DCS and Control System definition, Emergency shut-down system indication, instrumentation, relief and control valves with relief valve set pressure and control valve failure action Vendor’s scope

The P&IDs will be issued to Licensors and to Employer for review. (IFR) After the above issue, both Process and Engineering department, will mechanize (1st P&ID’s mechanization) the document including the information coming from the detail engineering activities; the minimum information shall be in compliance with IPS-E-PR-230 (Para. 11.2.1, 11.2.2, 11.2.3), ILA.PT.GEN.0001 (Para 3.2.6, 3.2.7, 3.3), ILA.PR.GEN.0003 (Appendix II, sh.13), PRG.IP.MEC.0008 and ILA.SM.GEN.0015 (Para 3.31). At the same time, internal review meetings between Process Leaders and Discipline Leaders are organized to define any necessary variation due to the development of project engineering and procurement or comments received by Licensor and Employer. The P&IDs will be sent to Licensor and to Employer for approval (IFA) and a formal P&ID’s review meeting with Licensors and Employer will be held. Actions recorded during P&ID’s review will be followed up. Upon agreement with Employer, P&ID’s will be issued Approved for design. (AFD) After the above issue, the HazOp review will be held. All HazOp recommendations will be transferred on the next P&ID’s issue. HAZOP Review is the most intensive review performed during the project. It will be performed under the direction of a Chairman with participation of Client’s representative and related discipline engineers. The Licensor will be requested to attend the HazOp Review for their units. Also manufacturer of critical packages could be requested to attend the HazOp of such supply. Contractor will incorporate all HAZOP recommendation with necessary resolution, Vendor information, detail design development and requirements to generate the issue “approved for design including HazOp recommendation”. The SIL Analysis will be performed on the above mentioned P&ID’s revision. After the “approved for design including HazOp recommendation” issue, necessary changes will be controlled by issuing notification of P&ID change. Notifications will be reviewed and registered by Team Engineering Management. They will indicate whether additional HAZOP review is required for the change. After the above issue Contractor will incorporate Vendor information, detail design development and requirements, final control valves / safety valves sizing in order to generate the P&ID’s issue for Construction. (IFC) At the end of the Project the as-built P&ID will be issued in order to incorporate all the changes required during construction, pre-commissioning and commissioning. (As Built)

DESCRIPTION OF P&ID’S WORKFLOW

The aim of the work process is to ensure the correct issue and management of P&ID’s within the framework of project execution activities. The objective is to graphically represent equipment, piping and instrumentation consistently with the plant functions, in order to facilitate the execution of engineering activities. The work process could be summarized in accordance with the workflow shown in the attached table (attachment No. 1). The workflow is applicable to each single Unit P&ID’s and should be customized in consideration of the particular characteristics of the Unit, of the Unit P&ID’s number, etc. 8.1

Contractor Workflow Description 8.1.1

P&ID’s for primary and auxiliary systems

The P&IDs for primary and auxiliary systems are developed according to the following phases. 8.1.1.1

Process Issue of the P&ID’s (IFR)

The preparation of P&IDs is carried out by the PRC on the basis of the information indicated in the PFDs, material and heat balances, equipment process data sheets and in line specifications plan prepared by TUB using the Material Selection Diagram produced by PRC. P&ID shall be checked by PRC to include the minimum process information required at this stage, according to operating procedure and responsibilities; these data are summarized and listed in the following procedures: • ILA.PT.GEN.0001 (Para 3.2.6, 3.2.7, 3.3); •

ILA.PR.GEN.0003 (Appendix II, sh.13)

Those working documents are jointly verified by TUB and SMAUT up to their issue. Preliminary versions of the P&IDs are however made available to HSEQ for performing the “hazard and operability review” and to any other departments involved in supporting the PRCs. In this phase, the process Systems and Subsystems are also identified. The PPL, with the support of the control team, issues the document in the advanced basic version (rev. A0). 8.1.1.2

First mechanization of the P&ID’s (IFA)

Basing on the process issue of the P&ID’s, a single P&ID’s Project Master Copy will be created by DTM (process) to be used by UT to include on the document its updated information, Client/Licensor comments and the result of the mechanization activities. The PPL of each unit will be responsible to manage the project master copy of the unit P&ID’s and, in any case, he will be available for any possible clarification / assistance to TUB and SMAUT during their mechanization activity. At the same time of mechanization, PRC shall include all the updated process information required at this stage and Licensor/Employer comments, in order to share this information with all the project team involved in the P&ID’s development. The TUB Dept. shall include the minimum piping information required at this stage, according to operating procedure and responsibilities; these data are summarized and listed in procedure PRG.IP.MEC.0008 At the end of the this activity, the TUB PSL shall sign each P&ID, and transmit the master copy to the SMAUT Dept informing PRC Dept.

PAGE 14 OF 147

The SMAUT Dept. shall include on the project P&ID’s master copy the minimum instrumentation and automation information required at this stage, according to operating procedure and responsibilities; these data are summarized and listed in procedure ILA.SM.GEN.0015 (Para 3.31) At the end of this activity, the SMAUT PSL shall sign each P&ID, transmit the master copy to the PRC Dept and to the TUB Dept. If available during the first mechanization phase, the preliminary vendor P&ID’s will be incorporated in the P&ID’s. The mechanization activity will be handled by the UT responsible for the package, with the contribution from the other disciplines, as applicable. The Deputy TM (Process), Process Leader for Process Unit or Process Leader for Auxiliary and Offsite shall organize the internal P&ID’s review meeting based on the project P&ID’s master copy as reference. PRC, TUB and SMAUT Depts will discuss and share in the multidisciplinary design review, the information included in the P&ID’s. The coordination and management of the design review will be provided by Deputy TM (Process), Process Leader for Process Unit or Process Leader for Auxiliary and Offsite or by any their delegate. On Deputy TM (Process), Process Leader for Process Unit or Process Leader for Auxiliary and Offsite request, others technical departments (HSEQ, MAPAF, etc) could be involved in the design review in order to support and assist the team. The design review team shall guarantee that the minimum information which should be included/added on the P&ID’s at this stage are in compliance with Client requirement IPS-E-PR-230 (Para. 11.2.1, 11.2.2, 11.2.3). The PPL shall draw up a Minute of Meeting where all the most important themes and, especially, the multidisciplinary themes, discussed in the meeting, will be summarized. Each PSL involved in the design review, as minimum, shall sign the minute of meeting and each P&ID discussed. At the end of the design review, the PPL will be responsible of drafting the shared P&ID’s project master copy and the PPL will issue the first mechanized P&ID’s (rev.A1) for approval by the TM (or Deputy TM). 8.1.1.3 Second P&ID mechanization The operating practices and fields of responsibility for second mechanization P&ID’s are the same as those for the first mechanization. The eventual modifications, intermediate between the existing revision of the P&ID’s and the subsequent, shall be transmitted by Internal Communication to all the involved depts. From this stage of the project, also the vendor P&ID’s will start to be available: these P&ID’s handled by the MAPAF Dept., shall be submitted to PRC, TUB, and SMAUT for the relevant comments and mechanization in parallel with the other project P&ID’s. In any case the design review team shall guarantee that the minimum information which should be included/added on the P&ID’s at that stage shall be in compliance with Employer requirement for that stage. After the P&I Diagram have been issued for construction, TM should start the Engineering “Close-out” procedure, according to ILA.GS.QUA.0001 for all the “hold” information of the P&ID’s issued for Construction. 8.1.2

P&ID’s for interconnections and utilities distribution

Since these P&ID’s are depending from the units layout, they are developed by TUB dept. For both types of P&ID’s, the line sizing is carried out by the PRC, while the PSL of the TUB department: - checks and issues the first mechanization of the document, making it available to the project team for the relevant comments; - checks the P&ID’s, after incorporating the agreed comments; - revises at a later stage the document, involving only the project positions directly interested. For the first revision of the P&ID’s the PPL of the Unit (Process, Utility, Offsite) will be responsible for the line sizing (accordingly to the available information at that time, highlighting hold points) of all the unit utilities distribution P&ID’s. Starting from the second revision of the P&ID’s, for the complex utilities network, like flare, cooling water, HP steam, MP steam, LP steam, Boiler Feed Water, etc, the relevant Utilities Unit PPLs, basing on their advanced and detailed process analysis, shall be responsible to check and eventually size/resize the lines of all the unit utilities distribution and unit interconnections for these Utilities. Basing but not limiting the analysis to the battery limit table, for the Interconnections P&ID’s, the following lines shall be sized by Process Unit PPLs (by the PPL responsible for the origin of the line): • From Process Unit to Process Unit

The P&ID’s for interconnections and utilities distribution will be, in any case, discussed and eventually commented in the internal design review before their issue. 8.1.3

Management of Vendor P&ID’s

The P&ID prepared by vendors shall strictly comply with the requirements included in this document. The Vendors shall, in any case, provide the drawing native file. P&ID’s for package systems and complex supplies on machine (auxiliaries side) are issued by the supplier. The control activity is handled by the UT responsible for the package, aided by the other project team for the relevant comments. After inputting the project documentation in the electronic management system, the UT shall: • ensure distribution to the other project team for the relevant comments; •

solve any problems of project uniformity and standardization;

•

carry out overall checking of the document before returning comments to the supplier.

The P&ID’s for package systems and complex supplies on machine and auxiliaries side will be, in any case, discussed in the internal design review before their issue. 8.2

INSTRUMENTATION 11.1

Scope

The purpose of this paragraph is to establish basic criteria to be followed for the identification of instrumentation and automation components on P&IDs, in order to provide a P&ID symbology which gives a reasonable understanding of the functions to be performed. Definition In the context of this specification the following definitions apply: ASCS CR CONTRACTOR C&E DCS EMPLOYER ESD FGS ISA I/P ITB MCC MMS MOV PLC PROJECT P&ID SPI SRR TGS 11.2

General

Instruments shall be identified on P&IDs by a system of letters and sequential numbers (Tag Numbers) in accordance with this specification which, in general, is based on ISA 5.1 and ISA 5.3 codes. It is not intended to depict detailed hardware aspects of instrumentation on P&IDs, only the functional requirements. To identify all aspects of the control and instrumentation, P&ID must be read in conjunction with the following documents: • Process Control Specifications, including control sketches and sequence charts • ESD Specifications, including C & E diagrams • Instrument Data Base (Instrument Schedule, Alarm /Trip Schedules) • Functional logic diagrams The following shall NOT be shown on P&IDs: • Symbols for valve positioners (pneumatic and/or electro pneumatic). • Balloons for field mounted I/P or P/I transducers, unless for stand alone installation (e.g.: I/P converters separately mounted from control valves). • Local process variable indicators on transmitter output, unless specifically required for operational reasons or to designate a special location for the indicator. In the first case an additional balloon, tangential to the transmitter balloon will be used, in the second case a note next to the tagging balloon shall be added.

Due to the implementation of the numbering code in SPI Tools, the prescriptions of the present specification are mandatory and deviations are not allowed. The use of the letters and digit codes is strictly restricted to the ones clearly listed in ATTACHMENT 3, tables IV, V, VI and VII. Codes not listed in the mentioned tables cannot be used unless previously agreed with EMPLOYER/CONTRACTOR. Measured or initiating variable letter code and function letter code For measured or initiating variable letter a single capital letter only shall be used. For function letter code a maximum of five (5) letters shall be used. For function letter code capital letter only shall be used. The measured or initiating variable letter shall identify the process condition/property measured or initiating variable, as per column 2 of the Table I in ATTACHMENT 3. The measured or initiating variable letter shall be followed by the function letter code without hyphens (refer to ATTACHMENT 3 - Table I, columns 3, 4 and 5). Where there are two or more succeeding letters, the priority of lettering shall be in the sequence TQIBRCSZAV e.g. PICA not PIAC, FQI not FIQ etc For computing functions the succeeding letter Y shall be used (HY where operator access is required) with qualifiers shown outside the balloon (refer to ATTACHMENT 3 - Table II). The relevant primary function letter shall be added to the Y, e.g. FY. Loop where initiating variable is not a process variable may use a letter code of more than one character (e.g. UV, XV, MOV , PSV, etc.). Refer to DOC. No. 3034-00-ED-IN-JSP-70087 “Job Specification for Smartplant Instrumentation”. Measured or initiating variable letter available codes and function letter available codes are summarized in the ATTACHMENT 3 - Table IV.

PAGE 95 OF 147

Unit identification Two (2) digits code only shall be used. Process units, auxiliary units and offsite units identification numbers are summarized in the ATTACHMENT 3 - Table VII. Serial number For numbers three (3) digits shall be used (001 up to 999), with the possible addition of one letter to identify specific functions of components which otherwise would have the same tag, e.g.: YHS-xx-001M and YHS-xx-001P respectively for Maintenance and Process Override Switches of the transmitter YZT-xx-001 connected to ESD. For the not-licensed units, numbering shall be parallel, i.e. a numerical sequence will start for each instrument function code first letter 'Y' and for each process unit designation 'xx'. All instruments part of the same loop shall have the same serial number 'zzz'. For numbering ranges reference is made to the ATTACHMENT 3 - Table VI. The process instruments and process loops serial number relevant to the Licensed Units shall follow the numbering philosophy specified in this procedure and not the Licensor philosophy (refer to ATTACHMENT 3 - table VII for the Licensed Unit list). Suffix In general. for suffix letter a single capital letter and digits shall be used. The suffix must not exceed three (3) letters/digits length. Suffix letter shall be used only for in case two or more instruments are required to satisfy the same process requirement. Such instruments shall be suffixed as follows: • Level Gauges: A = Top, B/C = Lower • Transmitters (general): A = High Range, B = Low Range • Transmitters (2ooN): A, B, . . , N • Indicators on transmitter output: NO SUFFIX= Control Room, A=Local • Valves: A = Positive (Pressure/Heat), B = Negative (Vent/Cool) • Chromatographs: A1÷An = First Stream Components (components from 01 to 99) B1÷Bn = Second Stream Components (components from 01 to 99) Z1÷Zn = Last Stream Components (components from 01 to 99) In general no suffix letter shall be used in the Loop numbering tag numbers. 11.3.2

Instruments in Packaged Units

Instruments supplied in packaged units shall be tagged according to the above mentioned criteria and within the serial number range shown in ATTACHMENT 3 - Table VI. However, due to presence of more packaged supplies in the same unit, it is necessary to assign restricted number ranges for each package supply. This range assignment will be defined at a later stage by Contractor.

ATTACHMENT “4” - Tie-ins numbering Procedure

Each tie-in point at BL should be specified by unique tie-in number. Only one Drawing containing the tie-in points will be prepared and issued by the piping department and it will used as reference by other disciplines (particularly for JV Internally use). Other disciplines should refer to this Drawing (if applicable) avoid to duplicate the tie-in inidation in the other drawings. Each Tie-in point will be indicated as below:

AAA BBB-CC

AAA: Is the abbreviation of the related discipline (e.g. CIV or PIP or ELE), BBB: Is the abbreviated Term regarding the Nature of Service, Media or other Character; the Abbreviated term shall be maintained in dedicated log. CC: is the two digit progressive Serial Nember for each Engineering Department (e.g. from 01 to 99 for Piping Dept.) Note: for Instrumentation Discipline as per PSL SMAUT discretion, the Serial number can be increased.

Examples: SWR-03 for Sea Water Return Tie-in CAT-03 for Catodic Protection Tie-in POW-002 for Power Tie-in
