PROBLEM TO BE SOLVED: To simply adjust buoyancy to an object to be laid in water.SOLUTION: A towing method for towing an object 1 to be laid, installed on a water bottom, in water by a ship S comprises: a coupling step of coupling, to the object 1 to be laid, a floating structure 2 including at least a floating body and a net-like bag body storing the floating body; a drawing step of connecting the object 1 to be laid to the ship S through a towline R, and drawing the object to be laid into water according to movement of the ship S; and a towing step of towing the object 1 to be laid, which is in a neutral floating state in water by coupling to the floating structure 2, to a place to be laid together with the floating structure 2 by the ship S.SELECTED DRAWING: Figure 1
【課題】水中での布設物に対する浮力を簡単に調節する。【解決手段】水底(B)に設置する布設物(1)を船舶(S)により水中で曳航する曳航方法であって、少なくとも1つの浮力体と当該浮力体を収容した網状の袋体とを備える浮力構造体(2)を布設物(1)に連結する連結工程と、布設物(1)を曳航索(R)により船舶(S)と接続し、船舶(S)の移動に応じて水中に引き込む引込み工程と、浮力構造体(2)の連結により水中で中性浮力の状態にした布設物(1)を布設場所まで浮力構造体(2)と共に船舶(S)により曳航する曳航工程と、を有する。【選択図】図1
