Offshore wind power platform provided with high-strength pile legs

Abstract

An offshore wind power platform provided with high-strength pile legs comprises a ship body, a lifting system, a hoisting mechanism and pile fixing chambers. The ship body is provided with a deck. The pile fixing chambers are arranged on the two sides of the deck. The lifting system is arranged in the pile fixing chambers and comprises lifting devices, fixing ring beams, the pile legs and pile shoes. The pile legs are inserted into the fixing ring beams in a sleeved mode. The lifting devices are arranged on the fixing ring beams. The pile shoes are arranged at the lower ends of the pile legs which are arranged in the pile fixing chambers in a sleeved mode. The hoisting mechanism is mounted at the top ends of the pile fixing chambers. According to the offshore wind power platform provided with the high-strength pile legs, the platform is provided with the rapid lifting pile legs which are high in rising and falling speed and high in bearing capacity, integrates the multiple functions of transportation of offshore wind power equipment, piling, mounting, adjustment, maintenance operation and the like, has the advantages of low construction cost, high reliability, high bearing capacity, low maintenance cost, high operation condition adaptability and the like, and is in the domestic leading level on the aspects of design and construction process.

Description

Technical field [0001] The invention relates to the technical field of marine engineering technology, and in particular to an offshore wind power platform with high-strength 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, lower wind turbulence, less wind shear, less restriction on various interferences, and no land occupation by 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 foreseeable that even if ...

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.
