Abstract: A shaft locking structure of a large LNG(Liquefied Natural Gas) couple shaft ship is provided to be easily installed in an emergency by locking a free wheel shaft in a slide bolting type to prevent damage to shafting. A shaft locking structure of a large LNG couple shaft ship includes a movable lower member(20) and an upper support member(30). The movable lower member is bolted with a shaft flange and locks a free wheel shaft(10) to fix shafting in an emergency requiring locking. The upper support member is slidably installed to be in contact with the movable lower member and has inner grooves(32) continuously connected to each member to fix and support a structure to be locked.

Abstract: An apparatus and a method for transmitting propulsive force in an LNG(Liquefied Natural Gas) carrier are provided to reduce cost for manufacture, maintenance, and repair by using a dummy shaft instead of an expensive clutch. An apparatus for transmitting propulsive force in an LNG carrier includes propeller shafts(20) and stoppers(50). The LNG carrier includes two main engines(10) and two propellers(30) corresponding to the main engines. The propeller shafts of the propellers are separably connected to the main engines respectively. The stoppers are installed around the propeller shafts respectively and selectively grip the propeller shafts to stop rotation of the propeller shafts. Dummy shafts(40) are installed between driving shafts(11) of the main engines and the propeller shafts of the propellers respectively.

Abstract: An apparatus for LNG carrier propulsion is provided to cope with breakdown of a main diesel engine by driving a propulsion axle by using an electric motor for propulsion receiving electric power for operation of boil-off gas reliquefying equipment during breakdown of the main diesel engine. An apparatus for LNG carrier propulsion comprises a main diesel engine(10), a propulsion axle(20), a power generator and an electric motor(40) for propulsion. The propulsion axle is connected to the main diesel engine so as to be separated. The electric motor for propulsion is connected to the propulsion axle so as to be separated, and receives electric power for operation of boil-off gas reliquefying equipment from the power generator.
