Fixation device
An elongate fixation device 1 for use in subsea anchoring has a triple nested stem arrangement, the innermost stem 2 of which has a cutter 9 disposed at a distal end and a tapered section 8 located adjacent to and proximally behind the cutter 9. An intermediate stem 3 surrounds at least a central portion of the inner stem 2 and has one or more flareable cutting fingers 7 at its distal end. An outer stem 4 surrounds a proximal portion of the intermediate stem 3. The inner 2 and intermediate 3 stems are coupled by a first releasable coupling 17 which when released allows relative axial motion along a first distance. The outer and intermediate stems are coupled by a second releasable coupling 18 which when released allows relative axial motion along a second distance. The intermediate stem 3 is nested within the outer stem 4 for at least a majority of the outer stem 4.
