摘要： PURPOSE: To prevent collision of a lifeboat with a depot ship during towing, by a method wherein, when a locking cable, stretched over between the center of the bow part of the lifeboat and the side of the depot ship, is connected to a towing cable stretched from the depot ship, the length of the locking cable set to a value between said connection and the center of the bow is set to a value longer than the length of the locking cable between the connection and the side of the depot ship.
CONSTITUTION: A locking cable 18 is stretched over between the central forward end 19 of the bow part of a lifeboat 2, which can be lowered from a depot ship, and a side part 20 facing the depot ship side. Meanwhile, a towing cable 12, having the base end mounted to the depot ship and the other end attached to the middle part of the locking cable 18, is stretched. A connecting position 23 allowing the towing cable 12 to be connected to the locking cable 18 is set such that length L
1 of a cable between the position 23 and the central forward end 19 of the bow part is longer than length L
2 of the cable between the position and the side. After the lifeboat 2 lands on the water from the depot ship, it is towed as it is, and this enables the lifeboat 2 to be automatically departed from the depot ship, and permits prevention of collision of the lifeboat with the depot ship during towing.

摘要： PURPOSE:To enable to keep a propeller submersed under the water at all times even under the condition that the diameter of the propeller is made larger than usual by a structure wherein the propeller is provided at the rear part of a space lying between right and left struts. CONSTITUTION:A pair of or right and left lower hulls 10 are submersed below the surface of the water and connected to an upper hull 11 by means of the struts 12 and further connected to each other by means of a horizontal connecting member 14. The propeller 22 is provided between the right and left struts 12 and mounted to supporting members 19. A rudder 15 is provided at the rear of the propeller 22. An engine is provided within the lower hull 10 in order to drive the propeller 22 by means of gears or the like. Due to the configuration that the propeller 22 is arranged between the struts 12 of the semisubmersible vessel, the propeller 22 can be submersed at all times even under the condition that the diameter of the propeller 22 is made larger than usual and consequently its propulsion efficiency is improved.
摘要翻译：目的：即使在螺旋桨的直径大于通常的情况下，螺旋桨始终浸没在水面以下，其中螺旋桨设置在左右两侧的空间的后部，支柱构成：一对或左右下部船体10浸没在水面之下，并通过支柱12连接到上部船体11，并通过水平连接构件14进一步连接。螺旋桨 22设置在右支柱12和左支柱12之间并安装到支撑构件19.在推进器22的后部设置有舵15.发动机设置在下船体10内，以便通过齿轮驱动螺旋桨22 或类似物。由于螺旋桨22布置在半可水容器的支柱12之间的结构，所以即使螺旋桨22的直径大于通常的螺旋桨22的直径，螺旋桨22也可以始终浸没，因此其推进效率为改进。
