1. PURPOSE The main objective of the hot oil pipe flushing for mechanical package is to ensure site fabrication piping and cooler for mechanical package is clean for the lube oil system. High velocity of oil flow will remove scale and dirt’s from the internal piping and through close loop circulation. The scale and dirt will be trapped at flushing strainer. 2. CODE AND STANDARD The ISO 4406 Cleanliness code range numbers for 4, 6 and 14 micron levels are 16/14/12 or lower (particle counter calibration per ISO 11171). 3. SCOPE The procedure covers the internal cleanliness of the pipeline and lube oil cooler by flushing loop. The designated pipeline number and lube oil cooler to be flushed is as below: 1. Gas Turbine Generator A/B/C/D/E/F with cooler 2. HP Fuel Compressor A/B with cooler 3. Gas Lift Compressors 1st Stage Packages A/B and 2nd Stage Packages A/B with cooler 4. Atmospheric Vapor Recovery Compressors A/B with cooler 5. Vapor Recovery Compressors 1st Stage Packages A/B and 2nd Stage Packages A/B with cooler Flushing loop must be done by interconnection external piping first. After flushing result is acceptable than continue flushing loop with interconnection piping with cooler package.

FLUSHING FLOWRATE

The following flushing sequence is required to minimize the possibility of contamination of components and assemblies.

It is to be followed at the manufacturing facilities and in the

field. Adherence to this sequence as prescribed in Figure 1, will substantially minimize the effort and the time necessary to successfully complete the flushing operations. Each flow line, cooler, etc. shall be flushed at a flow rate and temperature so that a minimum Reynolds number of 4000 is achieved through each section, or 150% of design flow, whichever is applicable. The Reynolds number can be calculated by: Nr = 3160.GPM CS.D Where: GPM = flushing fluid flow rate - gallons per minute CS D 7.

= flushing fluid viscosity - centistokes = pipe/tube inside diameter - inches

FLUSHING EXECUTION 7.1 SAFETY REQUIREMENT a) Ensure Job Safety Analysis (JSA) has been prepared, reviewed and approved by the authorize persons. b) Conduct safety toolbox meeting within the working crew in accordance with approved JSA. c) Prepare necessary work permits as required d) Ensure the use of the minimum Personal Protective Equipment (rain gear, rubber boots, rubber gloves, safety glasses and visor) for all personnel involved. e) Running water shall be made available at working area near the pump f)

Only personnel with adequate training shall execute hot oil flushing operations.

g) Personnel working within Pre/Commissioning Team must be fully aware of their duties, responsibilities and potential hazards associated with the system to be commissioned or tested. h) Material data sheet for the oil type is to be displayed in the secured area of the hot oil flushing unit. Personnel carrying out the work should be familiar with the information contained in the document. i)

Walkie-talkies for use by the Pre/Commissioning Team to be made available. Public announcement must be made when necessary. IDBC-TS-KPZZZ-…….Rev A HOT OIL FLUSHING PROCEDURE FOR MECHANICAL PACKAGE

Provide safety barriers on the affected working areas, especially surrounding piping and lube oil cooler.

k) Appropriate lighting and fire-fighting equipment must be readily available at site. l)

Necessary warning signs are also be required to provide at designated locations.

m) A safety risk assessment will be conducted prior commencing the flushing work. n) All Schedule waste has to manage to comply with Waste Management System

7.2 ORGANIZATION CHART The organisation chart during flushing execution as shown in attachment-1: a) Flushing leader is the responsible person for the successfully execution and coordinate overall preparation as per the approved plan. b) One supervisor with the crew will be assigned at flushing area. He will be responsible for all require preparation and execution activities. He will be a signal controller when the flushing is ready. c) One safetyman will be assigned at pig launcher area while one more other at pig receiver area. They will be responsible to secure the area boundary from unauthorized and relevant persons as well as advise the crews for any unsafe action and condition during the preparation and execution. 7.3 PRE-EXECUTION WORK The flushing will be executed after the completion of pneumatic test and air blowing of the pipe lines. A join inspection will be conducted between the Contractor and Client representative to ensure the reediness of pre-execution work are in placed with the agreed plan and safety requirement. 7.4 EXECUTION WORK -

Confirm lube oil cooler fan motor has been de-energized.

-

Confirm lube oil cooler pipes are cleaned before installation.

-

Confirm Air blowing of the external lube oil pipe line has been done.

-

Confirm oil for flushing is same specification with oil machinery.

A. Flushing Interconnecting External Piping STEP1: Preparation a. Line-up flushing equipment, hoses and fittings as per attachment for every package. Barricade the area of flushing activities. b. Filling temporary lube oil flushing tank up to 60% of the tank using oil filling. During filling lube oil flushing tank, filter shall be installed to prevent any contamination in original lube oil. c. For first flushing, install mesh 50 at the outlet spool piping. d. Priming flushing pump with oil by open pump suction valve (V1) and bleed through recycle valve (V2) back to tank. e. Open recycle valve (V2) to about 20% and ‘bump start’ the pump with discharge valve (V3) closed position. f. Restart flushing pump if there is no leak and slowly open more recycle valve (V2).

STEP2: Flushing loop with 50 mesh filter a. Line up V4, V5 & V6 and then slowly open V3 discharge valve and start filling L.O flushing for loop. Caution: 1) Monitor oil tank level closely, top-up oil into the tank if necessary. 2) Check all joints for any leak. If there is major leak, immediately stop flushing pump and repair leak.

b. When flow of oil return back to the flushing oil tank established, slowly closed recirculation line V2 and continue flushing loop for 2 hours. Caution: 1) Keep on monitor tank level and pump discharge pressure. 2) If pump discharge pressure increase more than 4 barg, stop flushing and prepare to clean or change filter basket.

c. Check wire mesh filter every 1 hour. Stop flushing when no dirt collected at 50 mesh filter.

STEP3: Flushing loop with 100 mesh filter a. Stop flushing pump and change strainer filter to 100 mesh and line-up through loop. b. Line up V4, V5 & V6 and then slowly open V3 discharge valve and start filling L.O flushing for loop. Caution: 1) Monitor oil tank level closely, top-up oil into the tank if necessary. 2) Check all joints for any leak. If there is major leak, immediately stop flushing pump and repair leak

c. When flow of oil return back to the flushing oil tank established, slowly closed recirculation line V2 and continue flushing loop for 2 hours. d. Inspect wire mesh filter every 1 hours and cleanness of the flushing oil/strainer. Stop flushing when no dirt collected at 100 mesh filter.

Figure 1. Typical PID for flushing equipment B. Flushing Interconnecting External Piping with Cooler STEP1: Preparation a. After the external pipe flushing result acceptable, connect external pipe with cooler package. b. For flushing, still using 100 mesh filter basket into the outlet spool. c. Priming flushing pump with oil by open pump suction valve (V1) and bleed through recirculation valve V2 back to tank. d. Open recirculation valve V2 minimum recycle line to about 20% and ‘bump start’ the pump. Restart flushing pump if there is no leak and slowly open more recycle valve (V2). 1) Monitor oil tank level closely, top-up oil into the tank if necessary. 2) Check all joints for any leak. If there is major leak, immediately stop flushing pump and repair leak

e. Line up V4, V5 & V6 and then slowly open V3 discharge valve and start filling L.O flushing for loop. Caution: 1) Monitor oil tank level closely, top-up oil into the tank if necessary. 2) Check all joints for any leak. If there is major leak, immediately stop flushing pump and repair leak

f. When flow of oil return back to the flushing oil tank established, slowly closed recirculation line V2 and continue flushing loop for 2 hours. g. Inspect wire mesh filter every 1 hours for cleanness of the flushing oil. Stop flushing when no dirt collected at 100 mesh filter.
