Emergency Shut Down Valve (ESDV) Skids

ESDV Image1Rev2The Emergency Shut-down Valve (ESDV) skid is designed to shut in flowlines and protect equipment downstream in the event of an upstream failure or surge. Major components include: subsea ball valves with mechanical and hydraulic connections, subsea swivels to accommodate rotation during installation, load-transfer skid to accept loading during installation, a protection structure and an ROV-interface panel.

The interface panel allows hydraulic actuation of either swivel or the ball valve.  Each of the three circuits has a dedicated hot stab port and hot stab plug.  The ball valve features a mechanical override that utilizes a torque bucket interface.   The assembly is an in-line style with integrated  17SV flanges for tie-in to the risers.
