An elongate fixation device 1 for use in subsea anchoring, and a method for installation. The device 1 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. First 17 and second 18 releasable couplings couple the intermediate stem 3 to the inner 2 and outer 4 stems respectively. All three stems are rotationally coupled to one another and the outer stem 4 has a rotationally driveable portion 10 and the inner stem 2 has a tensioning nut 12 for adjusting the relative axial positions of the inner 2 and outer 4 stems. The tensioning nut 12 and the driveable portion 10 are coupleable to a single rotational drive 23.
