Abstract

The invention belongs to the technical field of ships, and discloses a dual-fuel driven ship. The ship comprises a deck, a low-sulfur oil system, a methanol system, and a plurality of cargo oil cabins, a dirty oil cabin and an engine room which are sequentially arranged below the deck from head to tail, wherein the low-sulfur oil system is arranged in the cabin, the methanol system comprises a methanol daily cabinet, a methanol pump room and a methanol storage cabin, the methanol daily cabinet and the methanol pump room are arranged at the end, which is away from the cabin, of the deck, and the dirty oil cabin can also serve as the methanol storage cabin. According to the dual-fuel driven ship, on the basis of meeting the sulfur emission standard, the relevant provisions of arrangement ofa methanol system are met, the capacity of a cargo hold is not occupied, and the arrangement problem of the methanol system is solved.

Description

technical field [0001] The invention belongs to the technical field of ships, in particular to a ship driven by dual fuels. Background technique [0002] In order to reduce air pollution from ships, the global fuel oil content standard of 0.5% m / m came into effect on January 1, 2020. At present, there are three main ways for ships to meet this standard: 1. Adding and using low-sulfur fuel; 2. . Adopt marine desulfurization tower (exhaust gas cleaning system); 3. Use clean fuel (such as LNG, methanol, etc.) as an alternative fuel. The use of marine desulfurization towers is now regarded as transferring air pollution to seawater pollution, and has not fundamentally solved the problem of earth pollution. Therefore, more and more ship owners choose to use alternative fuels to meet the sulfur emission standards. The use of low-sulfur oil is the most direct and technologically mature system, but the use of low-sulfur oil is expensive and increases the cost of input. [0003] Th...
