Bulk cargo ship liquefied natural gas bunker arrangement structure

Abstract

The invention discloses a bulk cargo ship liquefied natural gas bunker arrangement structure which comprises a liquefied natural gas bunker. The liquefied natural gas bunker includes an outer shell and an inner shell, the liquefied natural gas bunker is arranged behind a superstructure, the liquefied natural gas bunker is embedded on an upper deck, the top of the liquefied natural gas bunker is flush with a middle deck of the superstructure, and the bottom of the liquefied natural gas bunker is flush with a platform of an engine room; the outer shell of the liquefied natural gas bunker is fixedly provided with an overhanging T-beam; and a web of the overhanging T-beam is fixedly connected to the outer shell, and the web of the overhanging T-beam is flush with a lower deck of the superstructure. The bulk cargo ship liquefied natural gas bunker arrangement structure effectively solves the problem about structural strength of the fuel bunker and can be used on the lower platform of the engine room, the utilization ratio in the height direction is higher, and layout of the entire engine room is more optimized.

Description

technical field [0001] The invention relates to the technical field of ships, in particular to an arrangement structure of a liquefied natural gas fuel tank of a bulk carrier. Background technique [0002] The use of LNG (liquefied natural gas) as fuel can meet the environmental protection requirements of gas emissions, and LNG fuel tanks are currently more and more widely used on ships. [0003] Membrane-type LNG fuel tanks are currently mainly used on large container ships and are arranged under the superstructure. "Research on LNG Fuel Tank Arrangement of Large Container Ships Propelled by Gas Turbine" (Wang Zhe, "Ship Engineering" Volume 40, 2018 Supplement 1) introduction: Considering the requirement of minimum container space loss when LNG fuel tank is arranged, determine the LNG fuel It is more reasonable for the tank to be located in the hull; at the same time, in order to effectively use the space and solve the practical problem that the tank cannot be packed under...

AI Technical Summary

Problems solved by technology

After the capacity of LNG fuel tank becomes larger, it becomes more and more difficult to arrange, which brings inconvenience to the overall design and layout of the ship type

[0006] The existing thin-film LNG fuel tank structure is applied to bulk carriers, and it is arranged below the deck. Facing the limited space in the engine room and a large number of equipment, it is difficult to arrange LNG fuel tanks; it is arranged above the deck, and the fuel tank is similar to a cantilever beam. Only the bottom and upper deck Welded, suspended on three sides, without support from the hull structure, the structural strength is very weak, and the safety is insufficient
