Remotely operated underwater redirection plenum chamber for spill response

A redirection plenum chamber comprising:

• a hull;
• and
• a cylindrical attachment system flexibly coupled to a first end of the hull, the attachment system further comprising:
• an actuator defined by the attachment system configured to selectively extend or retract a plurality of drive arms in concert with a plurality of drive cylinders mounted circularly around the actuator to form a drive system;
• a collar rigidly connected to a distal end of the at least one of the plurality of drive arms, the collar comprising a plurality of explosively activated barbs;
• and
• a grip surrounded by and mounted within the attachment system and comprising a conduit having an interior passage to provide fluid communication between the collar and a first inner pressure chamber the hull defines, the grip includes an annular seal concentrically arranged between at least two counter rotating cylinders threaded engagement with the conduit, configured to, upon counter rotation to suitably deform the annular seal to sealingly connect the hull with a riser pipe generally at its upper end.
