Problems solved by technology

One adopts a common structure with a large water plane, such as a large ship. The problem is that the volume and self-weight increase sharply with the increase of the span, which is severely limited in engineering.
The second is to use a small waterplane structure, such as a semi-submersible platform, which has a problem of greater dead weight, more complicated structure and operation, and higher cost
The third is to adopt a submerged structure. The problem is that the platform structure and operation are more complicated.

example 1

[0061] figure 1 , 2 and 3 represent a large-span truss type offshore floating platform 1, which is designed to be a floating airport at sea. The maximum wave height of the platform design extreme environment is 28 meters, that is, the width height is 14 meters. The operating environment is Class 6 sea state, and its upper limit wave height is about 6 meters.

[0062] The platform 1 has four floating bodies 2, connecting rods 3 and upper flight deck 4 arranged in parallel on the water surface. The floating body 2 is also a member of the truss at the same time. The platform deck is 300 meters long and 60 meters wide.

[0063] The floating body, the water working surface and the connecting rods are connected to each other to form an integral rigid truss structure, thus meeting the requirements of the aforementioned technical measure 1) in the technical solution of the present invention.

[0064] The following are the basic parameters of the platform structure.

example 2

[0088] Figure 8 Show that this example 2 platform has a square deck 4 ', side length 240 meters, has a large area flat deck, and the design purpose is a comprehensive base at sea, and has the ability to retract and release large-scale tethered balloons. The platform is designed for extreme environments with a maximum wave height of 28 meters. The working environment is 8 meters in wave height.

[0089] Cylindrical floating body 2' with a diameter of 3.2 meters, 16 vertically and horizontally, arranged orthogonally, at the intersection point p of the grid 1 ,p 2 Intersecting at all places, the vertical and horizontal grid spacing is 15 meters. The total volume of the floating body is about 59,000 cubic meters, the platform is fully loaded with a total weight of about 35,000 tons, and the height of the waterline is about 60% of the diameter of the floating body (1.85 meters). The distance from the lower edge of the platform deck structure to the upper edge of the floating b...

Abstract

An ultra-large truss type floating marine platform is composed of floating drums dispersed on water surface, a working platform above water surface, and connecting rods. Its advantage is high stability.

Description

technical field [0001] The invention relates to an offshore floating platform, in particular to an ultra-large truss type floating platform. [0002] The so-called super-large platform refers to a platform that has a larger span than conventional large-scale platforms and provides a large-span working space as its main function. Such as floating airports, integrated sea bases, etc. technical background [0003] In the current state of the art, one of the large floating installations that can stabilize in waves and survive storms is a large ship. It adopts a common large waterplane structure and is suitable for heavy-duty sailing. The problem is that its volume and self-weight increase sharply with the increase of scale, which is severely limited in engineering. Its large volume and deep draft lead to large wind and wave loads and large drifting resistance. When used as a floating platform, especially when it is super large, the construction cost is very high, and its moo...
