Semisubmersible supporting platform

Abstract

The invention provides a semisubmersible supporting platform. The semisubmersible supporting platform comprises a lower floating body, stand columns supported on the lower floating body, and a deck box supported by the stand columns, wherein an utility area module is arranged on the deck box, and is supported above a main deck of the deck box through supports; and a height interval is formed between the bottom of the utility area module and the main deck of the deck box. According to the semisubmersible supporting platform disclosed by the invention, the whole main deck of the semisubmersible supporting platform can be used for storing goods, so that the effective goods storing area of the deck is increased; the supporting capacity of the platform is high, so that the supply cycle of a supply ship can be reduced, and the cost is reduced; and a connecting manner of the utility area module and the deck box adopts support connection, so that the load effect of the deforming of the deck box to the utility area module is directly released, the stress condition of the utility area module is changed, especially, the fatigue strength performance of a joint structure of the utility area and the deck box is improved, and the reliability of the structure is improved.

Description

technical field [0001] The invention relates to the field of marine engineering equipment, in particular to a semi-submersible support platform. Background technique [0002] With the continuous development of deep sea oil and gas fields, shallow sea development technology has been difficult to meet the requirements. The semi-submersible platform has the advantages of excellent performance, small motion response, wide working water depth range, strong wind and wave resistance, large deck area and strong loading capacity. It has been widely used in the exploration and exploitation of offshore oil. With the development of the deep sea, there are more and more deep sea oil and gas fields, and the demand for semi-submersible living platforms serving deep sea oil and gas fields is also increasing, with higher performance requirements and a larger deck area to store more A large number of materials serve the exploitation of oil and gas fields. [0003] The structure of the tradi...
