Parinyarat needs some technical assistance here.
1) Please have ExxonMobil Thailand highlight in attached NP-4 and NP-7 well drawings which valve is leaking (the Manual and Actuated Valve have the same Part Number on the drawing. Need to get this right to ensure correct parts are quoted, ordered and supplied).
2) When they mention below “Repair Passing Valve” please have ExxonMobil confirm the Gate to Seat seal is leaking i.e. Gate Valve not holding pressure when in close position.
Please also confirm there are no other leaks for example Stem Packing, etc.
Once you have above info from ExxonMobil you can advise Cameron Singapore what parts are required and obtain the Quote direct from Cameron Singapore (parts will need to come from Cameron Singapore).
Cameron KL will provide Quote for Field Service Technician.
