Ship for selectively driving liquefied gas fueled main propulsion engine and liquefied gas fueled generator engine

摘要

A ship includes: a high-pressure injection engine (10) using fuel gas as fuel to obtain a propulsion power of the ship; a generator engine (20) using fuel gas as fuel so generate electricity; a motor (23) generating a power by using the electricity generated from the generator engine (20); a propulsion (40) propelling the ship; a main clutch (11) connecting the high-pressure injection engine (10) to the propulsion (40); an auxiliary clutch (24) connecting the gear box (30) to the propulsion (40); and a gear box (30) disposed in a front side of the propulsion (40) and power-connected to the main clutch (11) and the auxiliary clutch (24). The high-pressure injection engine (10) and the motor (23) are selectively power-connected to the propulsion (40) to obtain the propulsion power of the ship.
