Abstract
PURPOSE:To enable a submarine cable laid on the bottom of the sea in a very deep region, to be pulled up, by fitting a fitted-on unit at the tip of a wire, on the submarine cable, with the manipulator of a diving vessel. CONSTITUTION:A service vessel 1 is carried to a desired sea area near the position of a laid submarine cable 21, and from the service vessel 1, a reel 3 with a weight 4 is submerged into the sea. The reel 3 sinks on the bottom of the sea directing the weight 4 to a lower section. After that, from a supporting vessel 10 set near the service vessel 1, a diving vessel 11 is submerged toward the reel 3 on the bottom of the sea. The diving vessel 11 certainly approaches the reel 3 detecting signal from a binnacle 9 fitted on the reel 3. Then, by the manipulator 11a of the diving vessel 11, a fitted-on unit 7 at the tip of a reel wire 6 wound up on the reel 3 is grasped and is carried to a position just on the submarine cable 21. After that, by the operation of the manipulator 11a, the fitted-on unit 7 is moved down and is fitted on the submarine cable 21. After that, at the service vessel 1, a lift wire 2 is taken up by a winch 1a.
