Offshore hookup and commissioning


Except for a few innovative installations, wellheads and Christmas trees on platforms are basically the same as for land wells (see Fig 1 ). Control valves, safety valves, and piping outlets are configured the same and use the same or similar components. Some of the valves probably will have pneumatic or hydraulic actuators to facilitate remote and rapid closure in an emergency. Also, some Christmas trees may have composite block valves instead of individual valves flanged together.
