ABSTRACT:
In a method of and apparatus for anchor installation, a plate anchor is mounted at the bottom of a suction follower comprising a hollow cylinder having an open lower insertion end and a closable upper suspension end. The suction follower and the anchor secured thereto are engaged with the sea floor, whereupon water is pumped out of the suction follower causing the suction follower and the anchor to penetrate into the sea floor to a predetermined depth. The anchor is then disengaged from the suction follower, whereupon water is pumped into the suction follower to disengage the suction follower from the sea floor for recovery to the surface, leaving the anchor embedded in the sea floor.
