Subsea transfer hook adaptor

A subsea transfer hook having a lifting end and a tip end and an adaptor on the tip end, the adaptor comprising;

• a rigid U-shaped structure that is sized to be closely received and held in place by friction on and encapsulate the tip end of the subsea transfer hook;
• wherein the rigid U-shaped structure has a closed end and a closed side with the closed side of the U-shaped structure having a shape that matches the contour of the tip end of the subsea transfer hook;
• a padeye rigidly attached to the closed end of the U-shaped structure;
• and
• means for holding the U-shaped structure in position by friction on the tip end of the subsea transfer hook, comprising:
• the U-shaped structure having at least one threaded bore through a side of the U-shaped structure;
• and
• a bolt received through the at least one threaded bore in friction contact with the subsea transfer hook.
