INTERVENTION SYSTEM AND APPARATUS

摘要

A ball valve apparatus comprises a housing (62) defining a housing inlet (78) and a housing outlet (80) and a valve cartridge (64) mounted within the housing and defining a cartridge flow path extending between a cartridge inlet (74) and a cartridge outlet (76), wherein the cartridge inlet is arranged in fluid communication with the housing inlet and the cartridge outlet is arranged in fluid communication with the housing outlet. A ball valve member (96) is mounted within the valve cartridge and is rotatable to selectively open and close the cartridge flow path. A leak chamber (70) is defined between the housing and the cartridge for containing fluid leakage from the valve cartridge. A subsea system with a stress joint (28), a light weight intervention system (10) with an emergency disconnect (36) connector and a method for deploying a subsea system are moreover claimed.
