1 SEPARATION SYSTEMS The Separation Systems consists of the Test Header (GAY-0302) and the Test Separator (MBD-4501). The Header System is designed to collect and direct the well stream to the corresponding separator; the Separator is designed to separate the various components of the well stream. The Test Separator is a horizontal three phase vessel that separates the produced gas from the produced liquids and the produced oil from the produced water. Each component of the well stream is separated within the separator. Upon leaving the separator, the gas, oil and water are individually measured before being recombined and directed to the 6 Departing Pipeline to SS 182 C (KAA-0301). There is a shutdown valve (SDV) and a divert valve (DV) that work in conjunction with one another on the inlet of the vessel. If there is a process upset within the Test Separator the SDV closes and the DV opens, diverting flow around the Test Separator instead of the well being shut-in.

2 A. PRE-STARTUP PROCEDURE NOTICE: Refer to Preliminary Considerations in SECTION 3, PART A before beginning any start-up procedures. NOTICE: Any vessel purging should be done prior to getting system ready for start-up. 1. Test Separator (MBD-4501) a. Verify all vent and drain valves throughout the system are closed b. Verify manual valves are open or closed as necessary to correctly direct flow through the system c. Verify that all controllers and control valves are in-service and prepared for flow Liquid dump LCs/LCVs Gas Outlet PC/PCV Rev: 0 Date: 12/30/11 Page 2 of 5 SS 182 B

3 B. START-UP PROCEDURES 1. Reset the Test Separator (MBD-4501) on the Operator Interface Open the Shutdown Valve at separator inlet Close the Divert Valve at the separator inlet a. Verify that no safety devices are bypassed beyond those that must be bypassed for start-up (flag device as appropriate) on the Operator Interface b. Verify liquid level controllers and level switches have adequate instrument supply c. Monitor and place safety devices in service as they clear WARNING: Any operating parameter that is monitored by a safety device must be continuously monitored at all times while the safety device(s) are in bypass. The bypassed safety devices (indicators) must be flagged while in bypass and reset as they come in-service. REFER TO: Section 3 Part A for further details on bypassed devices. 2. Continue to monitor bypassed safety devices and reset as they come in service 3. Immediately begin using Normal Operating Procedures to continue monitoring system REFER TO: SECTION 5, PART D Rev: 0 Date: 12/30/11 Page 3 of 5 SS 182 B

4 C. SHUT-DOWN PROCEDURES WARNING: If complete process shut-down is required in order to shutdown the desired separation system, REFER TO: SECTION 4 NOTICE: Refer to Preliminary Considerations in SECTION 4, PART A before beginning any shut-down procedures. NOTICE: A facility process shut-down is required in order to shut-down the H.P. Production Separator, MBD Divert flow from the Test Separator to the Departing Pipelines as applicable a. KAH-0302, 6 Departing Pipeline to SS 193 A Open the manual header valve to divert flow to KAH-0302 Slowly close manual valve to isolate flow away from Test Separator, MBD Monitor system accepting diverted flow to ensure operation within safe Will new operating ranges need to be established? b. KAH-0800, 6 Departing Oil Pipeline to SS 182 C Open the manual header valve to divert flow to KAH-0800 Slowly close manual valve to isolate flow away from Test Separator, MBD Monitor system accepting diverted flow to ensure operation within safe Will new operating ranges need to be established? 2. If necessary, manually activate liquid dumps in separation system vessels before isolating all system inputs 3. Place the separation system safety devices that are likely to trip and cause a process shutdown in bypass and flag WARNING: Any operating parameter that is monitored by a safety device must be continuously monitored at all times while the safety device(s) are in bypass. The bypassed safety devices (indicators) must be flagged while in bypass and reset as they come in-service. REFER TO: Section 3 Part A for further details on bypassed devices.

5 4. Isolate the separation system a. Close all inlet manual valves to separation system b. Close gas discharge manual valves from system components c. Close oil dump manual valves from system components d. Close water dump manual valves from system components 5. Flag shut-down components as Out of Service 6. Open the manual gas relief/vent valve to bleed components to the relief system 7. Open the manual liquid drain valve to drain remaining liquid 8. Verify components are bled to 0 psig 9. Continue to monitor the other in-service systems for safe operating 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: 12/30/11 Page 5 of 5 SS 182 B
