Description

  The present invention relates to a method and an apparatus for recovering a lashing wire for fixing a block to be put into water to a hull, and more specifically, fixing a large number of blocks to a hull for each block group consisting of a plurality of blocks in an openable hold. By removing one end of the lashing wire from the hull, it is possible to efficiently recover the lashing wire that hangs underwater from the open hold after the fixed block is thrown into the water. The present invention relates to a method and an apparatus for recovering a secure lashing wire.

  In recent years, artificial mounds have been installed on the sea floor to raise deep water rich in nutrients, and by making the sea area rich in seawater and breeding plankton, etc. There are plans to form fishing grounds. In order to form such an artificial mound, the present inventors fixed a plurality of blocks as one block group on a work ship whose bottom of the hold is an openable type, and fixed to the hull by a lashing wire for each block group. When opening the bottom of the hold and putting these blocks into the seabed, remove one end of the lashing wire from the hull and leave it free for each block group. The method of throwing into the sea is proposed (refer patent document 1).

  According to this proposal, the blocks can be introduced without spreading over a wide range, and a mound with a high top can be efficiently formed on the seabed. However, after the block has been inserted, the lashing wire may hang down from the ship into the water and be pinched when closing the bottom of the hold. In such a state where the lashing wire is sandwiched, not only the bottom of the hold cannot be completely closed, but also the lashing wire cannot be routed in the hold to prepare for the next block, There was a problem that could not proceed smoothly.

If a large number of lashing wires hanging down in the water are simply pulled up on the ship, a lot of work time is required, and the work time becomes longer as the number of lashing wires increases, so work efficiency is poor. There was a problem.
