[0172] 1. Overview

[0173] Figure 6 , Figure 7 and Figure 8 An application of an ultra-large offshore base module is given. The base module is designed to be suitable for sea navigation and is propelled by 22 sets of azimuth propellers 4, which can be loaded on the open upper deck or other decks. Objects, helicopters, containers, etc., can also provide oil storage, refrigerated cargo storage, personnel living facilities, etc.

[0174] As shown in the figure, the basic module uses the statistical value of the maximum wave height that may occur in the sea area of ​​about 22 meters. The superstructure of the base module is designed as a box structure with three decks, which constitute the strength deck of the base module. For example, as shown, the length of the superstructure may be 600 meters, the width may be 151 meters, and the height may be 13 meters. It can provide 90,600 square meters of full access deck on the upper surface and 271,800 square meters of upper cabi...

Abstract

The invention discloses a basic module of an extra-large marine floating structure. The basic module is composed of a lower-portion floating body structure, an upper-portion structure and middle connecting structures. The lower-portion floating body structure comprises multiple dispersedly arranged floating bodies and is wholly in an extra-large water plane area form, the sum of the water discharging areas of the floating bodies is greater than the equivalent-quantity water volume of the whole weight of the floating structure, the upper-portion structure is a frame structure or a box body structure, the middle connecting structures are dispersedly arranged in space, and the lower-portion floating body structure is connected with the upper-portion structure through the middle connecting structures to form a hyperstatic combined space structure. Two basic modules can form the kilometer-level extra-large marine floating structure through one-time splicing. The basic module has very strong wave exciting load resistance and load change capability, has very strong sway-resistant stabilizing rigidity and can remarkably decrease relative motion during basic module splicing and connector load after splicing.

Description

technical field [0001] The present invention relates to a basic module of a Very Large Floating Structure (VLFS), and in particular to a single body that is between 400 meters and 800 meters in size and has a unique ability to resist swaying motion , the base module with a length of 800 meters to 1600 meters can be reached through one connection. Background technique [0002] In the activities of human beings to develop and explore the ocean, no matter what kind of functional purpose the offshore floating structure is used for, such as the comprehensive support base at sea, the ocean development community, the offshore tourism and entertainment platform, and the offshore industrial center, etc. There is an urgent need for large-scale structures. The scale of the box structure, ship structure and various offshore platform structures that have been implemented so far is still difficult to meet the huge needs of human beings for the development and exploration of the ocean. h...
