Problems solved by technology

[0008] For box-type platforms of conventional scale, there are also inherent shortcomings of large motion response and load response in waves
For semi-submersible platforms of conventional scale, there are also significant problems such as large structural height, deep draft, high center of gravity, large self-weight and displacement, and high construction costs.
These problems cannot be overcome only by optimizing the quantity of design parameters under the condition that the basic structural form remains unchanged.

Embodiment

[0106] Figure 9 Indicates a row-type offshore floating platform 1, which is designed to be a floating airport on the sea. The platform is designed for extreme environments with a maximum wave height of 28 meters. The working environment is Class 6 sea state, and the (1 / 3) significant wave height of the working environment is about 6 meters.

[0107] The floating body of this platform 1 is 4 buoys 2 arranged in parallel on the water surface, and has an upper flight deck 4 . The buoy 2, the deck 4 and the connecting rod 3 are connected to each other to form an overall rigid truss structure.

[0108] The following are the basic parameters of the platform structure.

[0109] The platform deck is 300 meters long and 60 meters wide.

[0110] The four buoys 2 are cylindrical, with a diameter of 4 meters and a length of 300 meters. The buoys are arranged in parallel on the horizontal plane, the distance between the centers of adjacent buoys is 15 meters, and the spacing is 11 me...

Abstract

The invention relates to a gang offshore floating platform, which diffuses several elongates float bowl on the water and fixes them with hack lever structure with integrated rigidity. The invention can be used as one basic structure of large and hype-large floaters, after the box and semi-sink platform. The invention can solve the problems of large load and lower rigidity of box type and high weigh, cost and deep draft of semi-sink type. The invention also provides a new floating concept of dynamic semi-sink small waterline area. And it has simple structure, lower weight, lower draft, stability, and the ability to reduce the load of wave and wind, avoid the limit of sea depth with lower cost and wider application of offshore exploitation.

Description

technical field [0001] The invention relates to an offshore floating platform, in particular to a row-type floating platform. It can be mainly applied to large or super-large platforms, such as offshore resource development and scientific research bases, offshore transfer bases, floating airports, offshore power stations, waste treatment plants, and various maritime military equipment carriers or military bases; it can also be applied It is used for temporary docks of conventional scales, multi-floor barges, etc. Background technique [0002] With the rapid expansion of the earth's population, the use of land resources is becoming increasingly limited, and all countries are expanding their economic activities to the sea. The ocean occupies 2 / 3 of the earth's total area, and has extremely rich seawater chemical resources, seabed mineral resources, marine power resources and biological resources. In the 21st century, human beings will enter the era of marine economy in an al...
