Low-flash-point fuel ship

Abstract

The invention relates to the technical field of ship construction, in particular to a low-flash-point fuel ship, which comprises a low-flash-point fuel cabin, a low-flash-point fuel cabin and a low-flash-point fuel cabin, each fuel cabin is of an enclosure bulkhead structure with two open ends, the opening directions of the fuel cabins extend in the front-back direction of the ship, the two fuel cabins are arranged on decks on the left side and the right side of the ship respectively, and the fuel cabins are used for containing low-flash-point fuel cabins; the ventilation mast is used for ventilation of the low-flash-point fuel cabin, and the ventilation mast is arranged on a tail deck of the ship; the fuel equipment room is used for arranging low-flash-point fuel treatment equipment and pipelines, the electrical equipment room is used for arranging electrical equipment for low-flash-point fuel treatment, and the fuel equipment room and the electrical equipment room are arranged on decks on the left side and the right side of the ship respectively and located between a ventilation mast and a fuel cabin. Reasonable site selection is carried out on key places such as a fuel cabin place, a ventilation mast, a fuel equipment room and an electrical equipment room, and it is ensured that a low-flash-point fuel ship reaches the safety level equal to that of fuel oil.

Description

technical field [0001] The invention relates to the technical field of ship building, in particular to a low-flash point fuel ship. Background technique [0002] At present, more than 90% of existing ships use fuel oil with a flash point greater than 60°C as the main energy source. Fuel oil tanks and equipment are mainly arranged in the engine room area, and the technology is simple and mature. With the increasingly stringent requirements of international maritime regulations on the emission of carbon oxides, sulfur oxides and particulate matter, energy transformation has become inevitable. The shipping industry generally believes that liquefied natural gas, liquefied petroleum gas, methanol, ammonia fuel and hydrogen fuel will be the most promising alternative energy sources. However, these alternative energy sources are all low flash point (less than 60°C) fuels and cannot be arranged in the engine room. Existing technical solutions cannot meet the marine application req...

Problems solved by technology

However, these alternative energy sources are fuels with low flash point (less than 60°C) and cannot be arranged in the cabin

Existing technical solutions cannot meet the marine application requirements of low flash point fuels

[0003] The main defects of the existing technical solutions: 1) The fuel tank is designed according to the flash point greater than 60°C, which does not meet the application requirements of low flash point fuel; 2) The fuel storage tank is arranged in the engine room, which is not suitable for low flash point fuel; 3) Fuel processing equipment is arranged in the engine room, which is not suitable for low-flash point fuels; 4) Low-flash point fuels generally have low-temperature, toxic, and flammable characteristics. The existing design does not meet low flash point in terms of fire prevention, ventilation, and ventilation. fuel usage requirements
