To provide a steam line of an LNG carrier in which the mono-fuel combustion of a natural gas in a boiler can be performed even in a maneuvering area.
When a load of a steam turbine 12 for a main engine is lower than a predetermined value, a boiler 11 always generates a steam flow more than the steam flow required by the steam turbine for the main engine. Accordingly, a steam line 1 of an LNG carrier includes a main steam pipe 2 and a dump steam pipe 3. When there is a load-up request for increasing a load of the steam turbine 12 for the main engine, a flow control valve 46 is operated in a closing direction, and a flow rate of steam passing the dump steam pipe 3 is decreased instantly, and thereby the flow rate of steam led to the steam turbine 12 for the main engine is increased instantly through the steam line 2 for the main engine by that amount.
