LNG fuel tank system for at least one gas engine used for the propulsion of a vessel

摘要

An LNG fuel tank system for at least one gas engine used for the propulsion of vessels, comprising at least one LNG fuel tank (4) and a gas tank (8), the LNG fuel tank being supplied with fuel from an onshore LNG pressure tank refueling facility by means of a LNG refueling pipe (1), characterized in that the LNG fuel tank (4) is a controlled atmospheric pressure LNG vessel tank low pressure, and the gas tank (8) is a single wall non-insulated pressure tank arranged to accumulate evolved and evaporated gas during LNG fueling and relieve the pressure of the LNG fuel tank, respectively, and because The gas engines are fed either from the gas tank (8) or from the LNG fuel tank (4), depending on a predefined pressure of the gas tank.
