Embodiment Construction

[0027] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments, but not as a limitation of the present invention.

[0028] Such as Figure 1 to Figure 8 As shown, the present invention provides a VLCC, including the VLCC cargo hold area, which also includes:

[0029] One longitudinal bulkhead 1, only one longitudinal bulkhead 1 is arranged in the cargo tank area of ​​the VLCC, and it is preferably arranged on the central axis of the oil tanker;

[0030] The main support members 2, the main support members have obvious truss-like characteristics21, including: while increasing the end connection area and section modulus of the vertical girders of the longitudinal bulkhead, the deck webs and the horizontal girders of the transverse bulkhead, all the main support members Large and small openings 22 are provided in the lower stress area of ​​the member. In addition, the lower stress area of ​​the web of the main ...

Abstract

The invention provides a single longitudinal bulkhead type supertanker, comprising a cargo space area. The supertanker also comprises a longitudinal bulkhead, a plurality of transverse bulkheads and main support components. The longitudinal bulkhead and the plurality of transverse bulkheads are vertically connected; the longitudinal bulkhead and the plurality of transverse bulkheads are arranged in the cargo space area and used for dividing the cargo space area into a plurality of cargo spaces; the main support components are arranged in the plurality of cargo spaces and used for supporting the cargo spaces. By adopting the technical scheme, the structure weight of the supertanker can be smaller, the processes are less, and the structure fatigue life is longer than the design life of the traditional VLCC by more than 30%.

Description

technical field [0001] The invention belongs to the technical field of ships and relates to an oil tanker, in particular to a super large oil tanker with a single longitudinal bulkhead. Background technique [0002] Since the birth of very large crude carrier (VLCC), regardless of whether it has double bottom and double hull or not, it has always maintained the subdivision form of two longitudinal bulkheads in the cargo hold area. Such as Figure 9 to Figure 11 As shown, the main support members of the traditional VLCC cargo area adopt the structural form of single-span beams and high-web girders. Its structure is relatively complicated and the process is complicated. Contents of the invention [0003] In view of the defects in the above technical solutions, in order to solve the above problems, the present invention provides a very large oil tanker. [0004] A very large oil tanker, including a cargo hold area, and also includes a longitudinal bulkhead, several transver...
