Large on-water floating structure

Abstract

The invention discloses a large on-water floating structure which comprises multiple lower-portion floating bodies, upper-portion structures and middle connecting structures. Each lower-portion floating body comprises multiple dispersedly arranged strip-shaped floating bodies, the floating bodies are spaced for a certain distance, the sum of water discharging volumes of the floating bodies is greater than that of the floating structure in a whole full-load state. Each middle connecting structure at least comprises multiple connecting structures in the first direction, the first direction is intersected with a horizontal plane, the single strip-shaped floating bodies corresponding to the connecting structures in the first direction are connected with three or more mutually spaced structures, and the cross section widths of the middle connecting structures in the horizontal direction are smaller than the widths of the corresponding strip-shaped floating bodies. The on-water floating structure is wholly in an ultra-flat shape. The large on-water floating structure has a wave height nonlinear response characteristic, can reduce wave load, can achieve ultra large scale, has excellent wave resistance, has structural integrity and stable height redundancy and has the characteristics of no disassembly and no capsizing and sinking under the accident conditions such as collision, reef striking and stranding, and the safety of the floating structure and the life safety of persons on the structure can be ensured.

Description

technical field

[0001] The invention relates to a floating structure on water, in particular to a new large floating structure on water in marine engineering. Background technique

[0002] The so-called large-scale floating structure on water refers to a floating structure on water that is larger in size than conventional floating structures on water and whose main function is to provide a large area of ​​work space. Such as artificial floating islands on the sea, floating airports, etc. The first problem that needs to be solved for large-scale floating structures is that the conventional box-shaped floating body will cause a sharp increase in the load (bending moment, shear force, and torque) caused by waves with the increase of the main scale of the structure, so that it exceeds the limit of the structure. strength. In addition, as the scale of the existing ships or floating structures increases, the number of items and people carried increases significantly, and the con...

[0113] 1. Overview

[0114] Figure 6 , Figure 7 and Figure 8 An application of an ultra-large offshore floating structure is given. The floating structure is designed to be suitable for sea navigation and is propelled by 18 sets of azimuth propellers 4. It can be used on the open deck or other The deck is loaded with large objects, helicopters, containers, etc. It can also provide oil storage, refrigerated cargo storage, personnel living facilities, etc.

[0115] 2. Structural form

[0116] The overall structure of the floating structure is designed into three distinct parts (see Figure 6 , Figure 7 and Figure 8 ), that is, the upper structure 1, the lower multi-floating body 3, and the intermediate connection structure 2 connecting the upper structure 1 and the lower multi-floating body 3.
