Commission Anchora. .r e e I spoke to Marty Scheerer on August 08, 1995 about the following events that were reported for April: Flow Station 2 04/12/95 Inlet air high DP shutdown T/C 1803 DP means delta pressure. The inlet air sucks air into the machines. If ice builds up in the screens, they will plug off and shut down the machines. This was a false dp caused by an instrumentation problem. Someone had to come in and recalibrate the sensor. 04/20/95 Manually depressured 4B, 4C, and 4D for maintenance work. They shutdown drill site 4 to change out the well divert valves and the low pressure drain valves on drill site 4. Volume flared was depressurization volume. 04/20/95 Started motor used to spin turbine for water wash on 1804 When they're water washing a compressor, it's not in service. They use fuel gas to start a starting motor. The production rates are cut back before the turbine is shut down. When water washing, they spray the turbine blades with water and sometimes detergent to clean the blades. They loosen soot and deposits that have built up, increasing efficiency. 04/21/95 Ran 1803 in crank mode for water wash This is the same as the operation on the 20th, just using a little different terminology. Gàs is used with an air powered motor. When they are water washing the compressor isn't in service. They use fuel gas to use the starter motor. The rates are cut back before the turbine is shut down. Crank mode just means that they're using this starter motor to spin the turbine blades while they wash them with a water and detergent mix to clean the blades. Flow Station 3 04/20/95 1806 cranking for wheel space cool down. Turbine maintenance 1806 is the artificial lift compressor. Cranking for wheel space cooldown means that they are slowly cooling down the machine. If they shut it down too fast, they can bow the turbine shaft, causing severe damage. The amount of time spent cooling down varies with ambient temperatures and operators. They check the exhaust temperature to tell when the equipment is cooled down enough. The inlet air has to be compressed, so they have to cool the machine down evenly with a starting motor. Wheel space refers to the different areas between the different stages. Since this is the gas lift compressor, they initially shut in wells, but start bringing them back on line as the gas lift falls off. This is maintenance flaring and not production flaring. Wheelspace cooldown is like a boroscope, but they look at the firing . e e 04/20195 1806 suction piping depressured for suction scrubbed valve replacement This is the vessel before the suction. It has an internal cyclone, which deflects gas to the side as it travels upward, to knock out liquids. The liquid drain valve may have malfunctioned. The volume flared was depressurization volume. The scrubber is isolated from the wheelspace cooldown, so the earlier operation in the day had not impact on the volume flared in this instance. The liquid outlet valve was leaking, so it was replaced. 04/29195 Water washed 1806 This operation is the same as that mentioned above for Flow Station 2. CCP 04/08/95 Flare system testing This is a very common event, required by another state agency. CGF 04/08/95 Process upset in MI section of facility. MI compressor 1855 shutdown. Compressor 1856, part of the waste heat recovery system, had a high exhaust pressure. They had to slow it way down, which upset the L TS (low temperature separation) system. The MI got a high, high level into the suction scrubber. The first time the MI compressor went down at 07:05 on a delta fuel oil pressure. They tried to restart it and at 08:30 it went down on a high, high level. at 09:30 they tried to restart it again but it wouldn't load. 04/23/95 1812 TIC at CCP shutdown High vibrations caused the TIC 1812 at CCP to shut down.. CGF has a higher flare capacity, so it's very common for CCP to send their gas over to CGF to be flared. The volume flared included shutdown, restart and water wash volumes. 04/27/95 L TS #2 turnaround deinventory gas and liquids (black smoke) They shut down L TS #2 and added a deflector. The original was a bad design. They added a 1/2 pipe, to make the gas change course. 04/28/95 Shutdown TIC 1855 for boroscope and water wash TIC 1855 is the MI compressor. A boroscope was done on the GG, which is the gas generator turbine that drives the compressor. They introduce a water and detergent mist to clean the soot and deposits off of the turbine blades. The boroscope is a flexible optical tool which they ise to look for cracks and flaws on the turbine blades. e e 04/29/95 Started TIC 1855 They had a 10 stage cooling error leak on the gas generator, fixed the lube oil leaks, and fixed the exhaust boot.

UNPlANNED Repaired Servo valve tubing on 1802 and brought unit back on line. I spoke to John Minier on June 12, 1995 about the following events that were reported for January: Flow Station 1 01/19195 TIC 1802 SID due to suction scrubber high level The gas goes into the suction scrubber before it goes into the compressors, and it drops out liquid. A liquid slug will overload it and it becomes a safety concern. It had a drain valve, but if a slug comes in it may not drain fast enough. If the liquid gets through the scrubber and into the compressor it can do major internal damage. They shut down the compressor and tried to start a second compressor. It wouldn't start so they had to vent until they got the situation under control. Flow Station 2 01/29195 Excessive inlet gas rates This was an intermittent problem. He suspected an increase in ambient temperature caused it. Flow Station 3 01/05195 TIC 1802 aborted starts due to instlmech malfunction 01/06/95 He didn't know what the problem was but said that he'd check into it ---- I spoke to Adrian McCaa on June 20th about this. He said that for some reason the compressor wouldn't go through the start sequence properly. Ther's a series ofintemal checks that it does at start-up and if one instrument is out of tolerance, it won't start up. He didn't know the exact cause but said it was probably something little like a contact or switch or controller card problem and not much gas was flared. 01/29195 TIC 1802 SID due to servo valve tubing broke He said servo valve tubing breakage is stress induced and felt certain that it had nothing to do with the events earlier in the month. 1801 was unable to load due to mechanical problems with IP discharge valve, so they had to get 1802 back on line. I spoke to Adrian McCaa further about this. The servo-valve supplies fuel gas to the compressors. The tubing broke, cutting the fuel supply. Hence, the compressor wasn't getting enough fuel to operate. The IP discharge valve controls backpressure on the compressor. e - CGF 01/1 1/95 MI compressors 1855 & 1805 shutdown due to master pressure controller failure MI is miscible injectant. As the gas is brought into CGF the first vessel is the chiller, then a low temp. separator. Next the dry gas gets sent to CCP from the top. The bottom is in liquid stage and goes to a stabilizer where it is heated. The lower product of this phase is NGL and the top is miscible injectant. Miscible injectant is pressure controlled. It is compressed for reinjection back into the field. With the MI compressors down, they still have gas coming off of the stabilizer. their only two choices are to flare it or shut down the entire facility. If they shut down the facility, fieldwide production rates will drop. 4-16 hours is a reasonable time frame for repairing these compressors. At the flow stations, the 1801 and 1802 compressors (2nd and 3rd stage) S.T.V.I.P. - should be anywhere from IS minutes to 2 or 3 hours for repairs. When the CCP shutdown affect the CGF they usually only can cut rates in planned situations. If it's an unplanned event, the problem is usually fixed by the time the rates would have been lowered. CCP 01/28/95 TC 18 I 2 SID due to an eleclinstr malfunction He didn't know exactly what the problem was and had to check. I spoke to Adrian McCaa on June 20th about this and he said the 18 I 2 was a high stage compressor. He checked but couldn't find out any more information about the instrumentation problem. e e
