Cabin structure of dual-fuel ship

Abstract

The invention provides a cabin structure of a dual-fuel ship. A cabin is arranged at the tail part of the dual-fuel ship, a cargo compartment is arranged at the front side of the cabin, an engine driving device for driving a stern propeller to rotate is arranged in an induced cabin, and a closed LNG tank storage chamber is arranged between the cabin and the cargo compartment. The LNG tank storage chamber is arranged between the cabin and the cargo hold in the width direction of the ship body; the LNG tank storage chamber is a whole coherent independent cavity or is divided into a plurality of independent sub-cabins through partition plates, the sub-cabins are transversely and/or longitudinally arranged in the LNG tank storage chamber, and environment sensors are installed in the independent cavity or all the sub-cabins and connected with the control cabin; and the LNG tank body is fixed in the LNG tank storage chamber through the damping base. The LNG tank storage chamber is formed between the cabin and the cargo bin, the occupied space of the LNG tank can be reduced, the space utilization rate of a ship is increased, meanwhile, the LNG tank is arranged near the cabin, and the number of pipelines of a power system can be reduced.

Description

technical field [0001] The invention relates to a dual-fuel drive ship, in particular to a cabin structure of a dual-fuel ship. Background technique [0002] In order to meet the requirements of green environmental protection, more and more marine propulsion devices use dual fuel (marine diesel + liquefied natural gas). Among them, liquefied natural gas (LNG) is usually stored in low-temperature and high-pressure containers. The shape of the LNG tank is generally a sphere or a cylinder, and a large, special compartment needs to be arranged in the hull for storage. [0003] Conventional LNG tanks are usually thin-walled spheres or cylinders due to internal high pressure. For this reason, it is necessary to arrange a large compartment on the ship, resulting in a waste of space; if arranged on the deck, wind and sun may cause The tank body is aging and has potential safety hazards. figure 1 It is an arrangement plan for a ship's LNG tank.
