SECTION E1 SUMP SYSTEM

Transcription

1 SUMP SYSTEM SS 182 A, A-aux. & C utilizes a Sump System to contain and send captured liquids back into the Skimmer Tank (ABM-1920). The Sump System consists of three sumps Sump Tank, ABH-1901 is located on the A - Platform. The captured oil is skimmed into the oil bucket. When a sufficient amount is accumulated the oil is pumped to the Skimmer Tank via two pneumatic diaphragm Sump Pumps, (PBH-1901/1902). The water flows through the Sump to the water outfall line discharging overboard. Sump Tank, ABH-1902 is located on the A-aux. - Platform. The captured oil is skimmed into the oil bucket. When a sufficient amount is accumulated the oil is pumped to the Skimmer Tank via two pneumatic diaphragm Sump Pumps, (PBH-1904/1905). The water flows through the Sump to the water outfall line discharging overboard. Sump Tank, ABH-1940 is located on the Drill Platform. The captured oil is skimmed into the oil bucket. When a sufficient amount is accumulated the oil is pumped to the Skimmer Tank via two pneumatic diaphragm Sump Pumps, (PBH-1945/1946). The water flows through the Sump to the water outfall line discharging overboard. Rev: 0 Date: 10/14/11 Page 1 of 5 SS 182 A, A-Aux & C

4 8. Verify each Sump LSH is in-service on the MCP a. Sump Tank, ABH-1901 (A - Platform) b. Sump Tank, ABH-1902 (A-aux - Platform) c. Sump Tank, ABH-1940 (C - Platform) 9. Manually activate each pump to ensure they are operational a. Sump Pump, PBH-1901/1902 (A - Platform) b. Sump Pumps, PBH-1904/1905 (A-aux. - Platform) c. Sump Pump, PBH-1945/1946 (C - Platform) 10. Immediately begin using Normal Operating Procedures to continue monitoring system REFER TO: SECTION 5, PART S Rev: 0 Date: 10/14/11 Page 4 of 5 SS 182 A, A-Aux & C

5 B. SHUT-DOWN PROCEDURES NOTICE: Refer to Preliminary Considerations in SECTION 4, PART A before beginning any shut-down procedures. 1. In order to shut-down the Sump (s) a facility process shut-in is required REFER TO: SECTION 4 (Facility Shutdown Procedure) 2. If necessary, the Sump Pump(s) can be shut-down for immediate maintenance/repair NOTICE: Shut-down of the Sump Pump(s) will cause a level to accumulate in the corresponding Sump Pile. The Sump must be monitored at all times and returned to service before a high level or additional shut-downs will be required. a. Manually activate the pump run signal at the Sump(s) to pump down the level in the Sump(s) oil bucket before shut-down of the pump b. Close manual block valves to isolate the pump suction, discharge and fuel gas supply c. Use appropriate collection to bleed down and drain before beginning work d. Continuously monitor the process system and the level within the Sump(s) so that further shut-down action can be taken as needed NOTICE: If shut-down was performed as preparation for maintenance work, or if the cause of the shutdown requires corrective action/repair, continue with Lock Out/Tag Out (LO/TO) Procedures REFER TO: Fieldwood Safe Work Practices for LO/TO (Section D Chapter 5) (can be found on the Fieldwood SEMS Portal) Rev: 0 Date: 11/15/11 Page 5 of 5 SS 182 A, A-AUX & C
