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.
