1. Internal wiring checks for PZT-0101A, PZT-0101B, PZT-0601 and SDV-0601.

Finding: Tag at PZT-0101A need to change to TB-B +123, TB-B -124 and PZT-0101B to TB-B +125, TB-B -126.

2. Continuity checks for instrument South West well area with Local Engineering personal. For production line two pressure transmitter PZT-0101A and PZT-0101B. For gas lift line is a PZT-0601 and SDV-0601. All pressure transmitter and shutdown valve solenoid A and B success for continuity checks.

3. Continuity check for instrument Abu Kecil 2 well area with Local Engineering personal. For production line two pressure transmitter PZT-0104A and PZT-0104B. For gas lift line is a PZT-0604 and SDV-0604. All pressure transmitter and shutdown valve solenoid A and B success for continuity checks.

1. Functional test for instrument South West well area with Local Engineering personal. For production line two pressure transmitter PZT-0101A and PZT-0101B. For gas lift line is a PZT-0601 and SDV-0601.

2. Inject pressure at PZT-0101A and PZT-0101B for gets HH (5680kpag) and LL (410kpag). Set point HH (PZAHH-0101A, PZAHH-0101B) and LL (PZALL-101A, PZALL-0101B) triggered at SIS and alarms display at DCS. Test successful.

3. Activate solenoid A (SXV-0601A) and solenoid B (SXV-0601B) for SDV-0601. Finding: Voltage from marshalling cabinet MDF4500B for solenoid A (SXV-0601A) and solenoid B (SXV-0601B) drop from 24V to 12V only. Although voltage drops, solenoid A and B still function SDV-0601 can open.

4. Functional test for instrument Abu Kecil well area with Local Engineering personal. For production line two pressure transmitter PZT-0104A and PZT-0104B. For gas lift line is a PZT-0604 and SDV-0604.

5. Inject pressure at PZT-0104A and PZT-0104B for gets HH (5680kpag) and LL (410kpag). Set point HH (PZAHH-0104A, PZAHH-0104B) and LL (PZALL-104A, PZALL-0104B) triggered at SIS and alarms display at DCS. Test successful.

6. Activate solenoid A (SXV-0604A) and solenoid B (SXV-0604B) for SDV-0604. Finding: Voltage from marshalling cabinet MDF4500B for solenoid A (SXV-0604A) and solenoid B (SXV-0604B) drop from 24V to 12V only. Although voltage drops, solenoid A and B still function and SDV-0604 can open.

20/10/2008 (Monday)

1. Functional test for valve SSV-0104 and SCSSV-0104 at Abu Kecil 2 well area with Local Engineering personal. Witness by operation (Mr.Rafidi).

2. Sequence to functional test SSV-0104 and SCSSV-0104 at Abu Kecil 2 well area:

- Apply MOS at PZT -0104A and PZT -0104B.

- Open SCSSV-0104. Pressure at PZT-0041B increased around 32000kpag.

- Open SSV-0104. Pressure at PZT-0041A increased.

- Closed SSV-0104.

- Disable MOS at PZT -0104A and PZT-0104B

- Pressurize at PZT-0104A and PZT-0104B to get a normal pressure.

- Open SSV-0104. Successful.

- Pressurize at PZT-0104A and PZT-0104B to get a HH setting.

- SIS triggered HH set point and SSV-0104 closed.

- Pressurize back at PZT-0104A and PZT-0104B to get a normal pressure

- Open SSV-0104.

- Pressurize at PZT-0104A and PZT-0104B to get a LL setting.

- SIS triggered LL set point and SSV-0104 closed.

3. Functional test for valve SSV-0104 and SCSSV-0104 successful.
