Dual-fuel bulk cargo ship

Abstract

The invention discloses a dual-fuel bulk cargo ship, which comprises a dual-fuel bulk cargo ship gas supply system. A main deck of the dual-fuel bulk cargo ship comprises a cargo hold area and an openarea. The open area is positioned at the stern; the open area comprises an extending area; the extending areas are located on the two sides of the stern and extend in the direction away from the midship. An extending part is arranged below the extending area to support the extending area, an upper-layer building is arranged on the side, close to the cargo hold area, of the open area, and the dual-fuel bulk cargo ship gas supply system comprises LNG fuel cabins which are arranged above the open area and located on the left side and the right side of the upper-layer building, a cabin which is arranged below the main deck, and a fuel gas treatment room which is arranged above the open area and located between the two LNG fuel cabins. Fuel in the LNG fuel cabins is conveyed to the fuel gas treatment room to be treated and conveyed to gas equipment in the cabin.

Description

technical field [0001] The invention relates to a dual-fuel bulk carrier. Background technique [0002] The dual-fuel bulk carrier can be applied to different routes. The gas supply system of the dual-fuel bulk carrier generally has an LNG fuel tank, an engine room and a gas treatment room. Gas equipment provides gas fuel, and LNG is stored in the tank in liquid form. The temperature of LNG in liquid state is about –163°C under normal pressure. [0003] The arrangement of LNG fuel tanks on the ship should first consider safety, and should meet the requirements of IGF for the location of LNG fuel storage tanks, and ensure that the distance between LNG fuel tanks and the side and bottom shell plate meets the requirements, so that LNG fuel tanks can meet the requirements when the ship collides or The probability of damage after grounding is minimized; at the same time, comprehensive consideration is given to the influence of LNG fuel tanks on the stability of the ship, the div...

AI Technical Summary

Problems solved by technology

[0005] The technical problem to be solved by the present invention is to overcome the defects in the prior art that the volume of the LNG fuel tank is large, the LNG fuel gas supply system is complicated, the layout is difficult, and the LNG fuel tank is difficult to be reasonably arranged on the main deck, and a dual-fuel diffuser is provided. cargo ship
