The invention discloses a multi-mode gas management and control system which comprises a pressure management system, a fuel supply control system, a reliquefaction control system, a recombustion control system and a ventilation mast emptying control system. The pressure management system is used for selecting a navigation pressure mode and a cargo hold pressure control mode. The fuel supply control system is used for providing fuel gas with stable pressure for the power generation main engine and the propulsion main engine; the reliquefaction control system reduces the BOG evaporation rate by reducing the temperature and pressure of the cargo hold, and the BOG of the cargo hold is cryogenically liquefied; the recombustion control system is used for protecting the pressure of the cargo hold; the ventilation mast emptying control system is used for exhausting gas into the atmosphere under the condition that the gas cannot be burnt and the ship is in the public sea. Pressure fluctuation interference of a unit-one mode is avoided, and safe and stable operation of the LNG transport ship is guaranteed.

    本发明公开了一种多模式气体管控系统,包括压力管理系统、燃料供应控制系统、再液化控制系统、再燃烧控制系统、透气桅放空控制系统,所述压力管理系统用于航行压力模式、货舱压力控制模式的选择;所述燃料供应控制系统用于为发电主机、推进主机提供稳定压力的燃料用气;所述再液化控制系统通过降低货舱温度和压力降低BOG蒸发率,将货舱BOG深冷液化;所述再燃烧控制系统用于保护货舱压力;所述透气桅放空控制系统用于在气体无法燃烧的情况下,且船舶处于公海时将气体排放到大气中。本发明避免单位一模式的压力波动干扰,保障LNG运输船安全稳定运行。
