Abstract

The invention discloses an LNG ventilating mast assembly and a ship including same. The LNG ventilating mast assembly comprises a first air hose, a second air hose, a first ventilating mast and a second ventilating mast, wherein the first ventilating mast and the second ventilating mast are located at the uppermost layer of the ship; one end of the first air hose is connected with an safety valve of an LNG tank, and the other end of the first air hose penetrates through the first ventilating mast and extends to a zero-level dangerous gas discharging outlet of the first ventilating mast; one end of the second air hose communicates with a TCS chamber of the LNG tank, and the other end of the second air hose penetrates through the second ventilating mast and extends to a first-level dangerous gas discharging outlet of the second ventilating mast; and the zero-level dangerous gas discharging outlet is higher than the first-level dangerous gas discharging outlet. According to the LNG ventilating mast assemble and ship with LNG ventilating mast assemble, the height of the zero-level dangerous gas discharging outlet is designed to be greater than the height of the first-level dangerous gas discharging outlet, and the problem that the zero-level dangerous gas turns back to the first-level dangerous gas discharging outlet and returns to the LNG tank along the second ventilating mast so as to affect the ventilating effect of the LNG tank is avoided.

Description

technical field [0001] The invention relates to the technical field of shipbuilding, in particular to an LNG venting mast assembly and a ship containing the LNG venting mast assembly. The ship can be a ship with LNG as a power source, or an LNG transport ship. Background technique [0002] At present, there are still relatively few domestic ships using LNG (liquefied natural gas) as a power source. For ships using LNG power systems as power sources, their LNG tanks are generally installed on the open deck, and there is no need to consider cabin ventilation. The ventilation masts used are purely for The system is breathable. [0003] For the LNG power system and the LNG carrier arranged in the cabin, the above-mentioned traditional ventilation mast cannot meet the ventilation requirements of the LNG tank. Contents of the invention [0004] An object of the present invention is to provide an LNG venting mast assembly, which can discharge dangerous gases in LNG tank compartm...
