Abstract
PURPOSE: To maintain effective and safe towing and prevent the damage of towing cable by arranging a towing cable so as to pass a roller pulley hanged down at the top end of a derrick boom, in towing the ship to be towed by a towing ship.
CONSTITUTION: A towing cable 9 extends to a substance to be towed form a winch 8, passing on two rollers of a roller pulley 10. The roller pulley 10 is hanged down from the top end of a derrick boom 7 by a cargo wire, and the derrick boom 7 is constituted so as to be able to freely turn right and left, having the base end 19 as a fulcrum, by freely setting a guy wire. Accordingly, even in the case when a towing ship varies a course, as the hanging-down point of the towing cable is not fixed, the point follows in the direction of the substance to be towed and fluctuates, so fatigue damage due to sharp angular bending of the towing cable 9 can be prevented.
