Novel upper wall pier and trunk channel based large corrugated bulkhead product oil tanker

Abstract

The invention discloses a novel upper wall pier and trunk channel based large corrugated bulkhead product oil tanker. Compared with the design type of the existing corrugated bulkhead ship upper wall pier and trunk channel ballast compartment, the width of a trunk channel is increased, the internal space of the trunk space is appropriately increased, meanwhile the upper wall pier and trunk channel is changed into a void compartment from the ballast compartment, the upper wall pier and trunk channel of a cargo space area is designed into a void compartment, the ratio of the width L of the trunk channel and the cargo space height H is within 1 to 35%, and accordingly the enough ballast water is ensured, the paint consumption of the integral ship is significantly reduced, the weight of the ship body structure is reduced, the labor cost is saved, the ship economy is improved, and the advanced environment-friendly concept is achieved.

Description

technical field [0001] The invention mainly relates to cabin division and arrangement technology in the field of ship design and construction. Background technique [0002] Since the late 1990s, the Middle East has successively started to build oil refineries, and the output of refined oil has gradually increased, which has promoted the enlargement of refined oil tankers. The 110,000-ton product oil tanker is favored by shipowners due to its large tonnage and good port adaptability, and has extensive market demand. [0003] In recent years, with the continuous promulgation and implementation of new international norms and rules and the implementation of international green, low-carbon and environmentally friendly shipbuilding concepts, the upgrading of existing leading ship types is imminent. It has become one of the main development characteristics and trends of large product oil tankers to reasonably improve ship economy and environmental protection by means of optimizing...

AI Technical Summary

Problems solved by technology

[0005] 1. It is necessary to meet the requirements of the PSPC standard for ballast tanks, and to spray protective paint inside the cabins. The amount of paint used is large, and the environmental protection of the ship is poor;

[0006] 2. The structure design in the cabin space is relatively complicated, the structure size is large and the weight is heavy, and the amount of steel used in shipbuilding is relatively large;

[0007] 3. Due to the small width of the trunk channel, large structural size and narrow space, the construction is difficult for personnel, the required construction time is long, the labor cost is high, and the ship's economy is poor
