A subsea shutoff device, in particular for use in water depths of more than 30 m for operating a valve with a gate with a waterproof, oil filled housing, a crank mechanism arranged in the housing, and a rotary actuator, wherein the rotary actuator is adapted to operate a gate of a valve via the crank mechanism.

Subsea shut-off device

A technique facilitates coupling of an electrical actuator () with a subsea host (). Effectively, mechanical and electrical connections are both formed during movement of the electrical actuator into engagement with the host. The electrical actuator is moved to a desired host location, and then the electrical actuator is guided into mechanical engagement with the host. During movement of the electrical actuator into mechanical engagement, a drive member () and at least one electrical connector () of the actuator are operatively coupled with corresponding features of the host, thus enabling engagement of the actuator and host with a simple installation motion.
