Problems solved by technology

[0008] However, for the above-mentioned ships, for example, the housing of the living quarters and the machinery room are separated, or the height and width of each superstructure are quite different due to the separate design of each superstructure.
Therefore, when the ship sails, there is a problem that the air flow is disturbed especially between the superstructures, and the wind pressure resistance increases, resulting in a decrease in the speed of the ship.

Abstract

Provided is a marine vessel having low wind pressure resistance in an upper structural body. A marine vessel comprises: a hull; and a first upper structural body set up on an upper deck of the hull, and having living quarters and an engine room casing adjacent to the living quarters toward the stern of the hull. The first upper structural body has a horizontal cross section formed into a streamlined shape, the living quarters and the engine room casing being formed to the same height.

Description

technical field [0001] The present invention relates to ships. Background technique [0002] For conventional large bulk carriers, oil tankers, etc., the steering room, the living quarters with crew quarters, etc., and the machinery room housing that accommodates the exhaust pipes from the internal combustion engine, etc., are mainly used to vent the exhaust of the internal combustion engine into the air. An upper structure such as a discharge chimney is installed on the upper deck (for example, refer to Patent Document 1). Such superstructures are respectively designed in the smallest shape suitable for various purposes.
