Wstton Systems has been awarded an order for the supply of two pressure protection systems to protect the production riser piping on the FPSO’s turret from an over-pressure event. The order consists of 2 pneumatic spring-return fail close actuators fitted to 12” Class 1500 ball valves, each with a control system to allow for ESD and partial valve stroke testing. The ESD function will be initiated via electronic pressure transmitters connected to a logic solver employing 2oo3 voting logic. The actuators will also to be fitted with closed loop breathing systems to help achieve the project specified 20 year design life.

Built in 1992, the refurbished Four Rainbow FPSO will operate in the Layang field which is located off the coast of Malaysia.
