Abstract: A method and apparatus for attaching by remote control a riser pipe to an offshore structure. The method includes installing one or more remotely operable pre-aligned jawed clamps upon the structure, suspending the riser pipe vertically over the side of the structure, guiding the pipe to a position between the open jaws of the clamps, and remotely closing the jaws about the riser pipe. The apparatus includes an arcuate seat rigidly attachable to the structure, a pair of arcuate jaws hingedly attached to the seat, and remotely controlled hydraulic piston and cylinder assemblies to move the jaws between an open position to receive the pipe and a closed position to hold the pipe.

Abstract: A quick operating connector for pipe or the like including a pair of coupling members, each adapted to be connected at one end thereof to one of said pipes. The first coupling member has an annular radially outward extending flange having a forward side and a rearward side with a radially inner portion and a radially outer portion. Both of the portions define the shape of a frustrum having a forwardly facing base, and the slope of the radially inner portion relative to the central axis of first coupling member is greater than that of the radially outer portion. The second coupling member has a housing for receiving the flange in mating engagement therewith. Disposed circumferentially about the housing is a plurality of self-locking cams which are radially inwardly and outwardly movable between a retracted position in which flange is receivable within the housing and an extended position in which the self-locking cams engage the radially inner portion of the flange in self-locking fashion.
