A connector assembly for emergency decoupling of a subsea end fitting of a movable subsea structure

A connector assembly for emergency decoupling of an end fitting of a movable subsea structure from a tubular fixed subsea structure, comprising:

• a first tubular body comprising a first end configured for receipt into, and releasable retention in, the fixed tubular subsea structure, a second end formed into a receiving socket portion and one or more recesses in an inner wall of the socket portion;
• a second tubular body having a first end configured for receipt into the socket portion of the first tubular body and a second end configured for connection to one end of the movable subsea structure;
• the connector assembly further comprising:
• a plurality of first coupling members mounted in the second tubular body and movable between an extended position in which they are received in the one or more recesses in the inner wall of the socket portion and a retracted position in which they are withdrawn from the one or more recesses;
• a locking member mounted in the second tubular body and movable between a first, engaged position in which it retains the first coupling members in their extended position and a second, disengaged position in which it allows the first coupling members to move towards their retracted position;
• and
• a frangible retaining member configured to retain the locking member in the first, engaged position.
