An offshore wind power platform with high-strength legs

Abstract

An offshore wind power platform with high-strength pile legs, including a hull, a lifting system, a hoisting mechanism and a pile-fixing room; a deck is arranged on the hull; the pile-fixing rooms are arranged on both sides of the deck, and the lifting system is arranged Inside; the lifting system includes a lifting device, a fixed ring beam, spud legs and spud shoes. Inside the pile-fixing chamber, the hoisting mechanism is installed on the top of the pile-fixing chamber. The present invention proposes an offshore wind power platform with high-strength pile legs, which has fast lifting speed and strong bearing capacity, and integrates multiple functions such as transportation, piling, installation, commissioning and maintenance of offshore wind power equipment. In one body, it has the advantages of low construction cost, high reliability, large carrying capacity, low maintenance cost and strong adaptability to operating conditions. Its design and construction technology are at the domestic leading level.

Description

technical field [0001] The invention relates to the technical field of marine engineering technology, in particular to an offshore wind power platform with high-strength pile legs. Background technique [0002] In order to achieve the goal of energy saving and emission reduction, my country is vigorously developing clean energy, and offshore wind power is one of the important energy sources. Compared with land, offshore wind power has the advantages of less environmental impact, better wind conditions than land, less wind turbulence intensity, less wind shear, less interference restrictions, and no land occupation for offshore wind farms. Offshore wind power is undoubtedly the trend of wind power development in the future. Offshore wind power will be the core of wind power development during the 13th Five-Year Plan. In the next two years, 44 offshore wind power projects will be put into operation, with a total installed capacity of 10.52 million kilowatts. It is foreseeabl...

AI Technical Summary

Problems solved by technology

[0003] At present, in the construction of offshore wind farms at home and abroad, there are few dedicated wind power installation platforms or ships, and jack-up platforms or crane ships used in the field of offshore oil and gas drilling are mostly used to complete the construction. At the same time, life supply ships are required to cooperate. The whole process Many ships are used, positioning is difficult, and efficiency is low; the manufacturing of marine engineering equipment has been basically transferred to Asia, but due to the high-tech barriers of marine engineering, domestic companies basically have no design capabilities, and mainly undertake low-end manufacturing

In addition, high-end offshore engineering equipment and its supporting equipment are basically monopolized by foreign countries, and their value is much higher than that of the hull. At present, it seems that my country still has little involvement in offshore engineering supporting equipment.
