Dual-fuel bulk cargo ship

Abstract

The invention relates to a dual-fuel bulk cargo ship, and belongs to the technical field of ship design. The ship comprises a superstructure, an upper deck, a gas fuel cabin, a fuel storage cabin, a cargo cabin and a cabin, wherein a superstructure is arranged on an upper deck, close to a stern, of the dual-fuel bulk cargo ship, a cabin is arranged in the ship body below the superstructure, a cargo hold is arranged in the ship body between the cabin and the bow of the dual-fuel bulk cargo ship, a gas fuel cabin is arranged on the upper deck, close to one side of the bow, of the superstructure,and a fuel storage cabin is arranged in the hull below the gas fuel cabin. The ship is advantaged in that a problem that a gas fuel cabin of a dual-fuel bulk cargo ship occupies a large space of a cargo hold and a cabin is solved, and reasonable arrangement of LNG tanks on the ship is achieved under the condition that the capacity of the cargo hold and the arrangement of the cabin are not affected. Operation economy of the ship is improved, greenhouse gas emission is reduced, and purposes of energy conservation and emission reduction of the ship are achieved.

Description

technical field [0001] The invention relates to a dual-fuel bulk carrier and belongs to the technical field of ship design. Background technique [0002] Generally, ships traditionally use fuel oil, heavy oil oil (HFO) or diesel oil (MDO) as propellant fuel. Compared with other fossil fuels, natural gas is considered a clean energy source because it only emits a small amount of carbon dioxide and a very small amount of nitrogen oxides when burned. Therefore, using natural gas as a marine fuel is considered to be an effective measure to reduce greenhouse gas emissions. In recent years, the international community has been calling for energy conservation and emission reduction, and a series of regulations and rules have been issued. Against this background, the problems of energy conservation and emission of traditional transport ships have become increasingly prominent. Due to the high carbon and sulfur content in the traditionally used fuel oil, finding new clean energy an...

Problems solved by technology

However, the different characteristics of the two types of fuels have brought difficulties to ship design

In the existing dual-fuel ships and related designs, the arrangement of LNG tanks either adopts membrane tanks, which are arranged between the engine room and the cargo hold, or uses C-type tanks, which are arranged in the engine room or the cargo hold space. These two options are not the same. Exceptions have a great impact on the arrangement of the engine room and cargo hold, or are arranged above the aft mooring deck, and the fuel tank space is limited, which restricts the implementation of the overall arrangement plan
