Abstract
Riser clamps are installed onto fixed or compliant offshore platforms by a diverless technique. Each riser clamp is rigidly or hingedly attached to a heavy tapered wedge. Mating tapered receptacles are built into the platform, preferably at various levels along a corner leg. Only one lift line is utilized which may be either a drill string or wire rope, and one remotely operated vehicle (ROV) for observation, to lower and stab each riser clamp into one of the tapered receptacles on the platform.
