Abstract

The invention discloses an LNG fuel boat fuel gas dual-wall pipe broken simulation box and a simulation method thereof. The LNG fuel boat fuel gas dual-wall pipe broken simulation box comprises a box body, a sealing plate for sealing the top of the box body, a simulation smoke exhaust pipe, a compression air inlet pipe, a smoke bomb throwing pipe and a pressure meter, the simulation smoke exhaust pipe, the compression air inlet pipe and the smoke bomb throwing pipe are all fixed to the sealing plate and are communicated with the inner cavity of the box body, the pressure meter is fixed to the sealing plate through a welding base, and a root valve is fixed to the welding base of the pressure meter. The simulation box can truly simulate a small-caliber broken leakage state of an LNG fuel boat fuel gas dual-wall pipe, the simulation box and a smoke bomb in the box can be repeatedly utilized, the cost is saved, and the workload of an LNG fuel boat fuel gas dual-pipe-wall broken monitoring experiment is lowered.

Description

technical field [0001] The invention relates to the technical field of shipbuilding, in particular to a damage simulation box and a simulation method for a gas double-wall pipe of an LNG fuel ship. Background technique [0002] On large LNG ships using dual-fuel engines, the volatile gas (Boil-off Gas) evaporated in the cargo hold is pressurized to 6bar by the BOG compressor, and the low-pressure BOG is sent to the main engine through the double-walled pipe after passing through the gas valve group. During ship operation, ship vibration and accidents may cause gas pipeline leakage accidents. If the gas continues to leak without taking effective measures, when the gas reaches a certain concentration, there will be an explosion hazard. [0003] In view of this situation, during the ship construction process, it is necessary to conduct damage simulation monitoring experiments on double-wall pipes, supplemented by analysis, and finally determine the sensor installation position...
