Abstract
A subsea connection unit for securing an offshore structure to a marine bottom is disclosed. The unit comprises a base adapted to be positioned on the marine bottom and an insert member adapted to be connected to the lower end of the offshore structure. The base has a recess thereon adapted to receive the insert member. Releasable vertical latch means comprised of a plurality of tapered shear blocks are carried by the insert member and cooperate with tapered lugs in the recess to lock the insert member against vertical movement within the recess. Releasable horizontal latch means comprised of a plurality of wedge members are positioned on the base around the recess and cooperate with load surfaces on the insert member to center and lock the insert member against horizontal movement within the recess.
