摘要： An elongate fixation device for use in subsea anchoring has three nested stems. The inner stem has a first length, a cutter disposed at a distal end and a tapered section located adjacent to the cutter. The intermediate stem has a second length less than the first length, and surrounds at least a central portion of the inner stem. The intermediate stem also has one or more flareable cutting fingers at its distal end. The outer stem has a portion for retaining the fixation device in a substrate, and a third length less than the first length. The outer stem surrounds a proximal portion of the intermediate stem and extends beyond a proximal end of the intermediate stem. The intermediate stem is nested within the outer stem for at least a majority of the outer stem. Releasable couplings allow for selective motion between the stems.
