• Subsea Isolation Valves

    Focusing of subsea safety NOV has developed a subsea isolation valve (SSIV). A Subsea Isolation Valve creates a safety barrier in case one needs to shut down a part of a flow line. 
     
    The main purpose of a SSIV is to protect the platform and its personnel from unintended release of hydrocarbons. The SSIV is designed fail safe, and will close on loss of an active signal from the ESD system. The SSIV can be installed as a standalone module or as an integrated component with, for example a PLEM or a riser base. It may be designed to be retrieved separately or as part of a pipeline or structure. The valve actuator is normally retrievable. The SSIV is typically SIL 2 rated.
