Installation method of offshore equipment

Abstract

The invention discloses an installation method of offshore equipment. The main technical means is that two ships cooperate with each other, after the two ships travel to destinations separately, a gantry crane type hoisting operation platform with an automatic lifting function is built quickly, and after operation is finished, the two ships are separated from each other and return to work or continue operating correspondingly. By means of the installation method of the offshore equipment, a boom is shifted from a cantilever state in an existing installation method to a two-end supporting state, the stress condition of the boom is improved, the action of capsizing moment is avoided, the stability and reliability during operation of hoisting equipment are enhanced, the two ships travel to the destinations independently and then are in lap joint quickly, the maneuverability is good, and the efficiency is high; and after installation work is finished, the two ships break up and can returnto work or continue operating correspondingly, the flexibility is quite high, independent work of the ships are not affected, the maximum utilization ratio of the ships is achieved, and the operationcost is further reduced.

Description

technical field [0001] The invention relates to the technical field of marine engineering, in particular to a method for installing offshore equipment. Background technique [0002] With the acceleration of industrialization, it is foreseeable that non-renewable mineral resources will be exhausted in the near future. Nowadays, the development of technological utilization of renewable energy has become an urgent task for mankind, especially in China, where the economy is developing rapidly. As one of the important renewable energy utilization technologies, offshore wind power has the advantages of abundant resources, better wind conditions than land, less environmental impact, and no occupation of land resources. There is no doubt that offshore wind power will be the main trend of wind power development in my country in the future . [0003] At present, the installation of offshore wind turbines is basically completed by two types of ships, jack-up lifting platforms and floa...

AI Technical Summary

Problems solved by technology

At present, most of the wind power installation ships used are equipped with jib cranes. The lifting capacity of the crane jib is affected by the working range, which limits the working range and capacity of the crane to a certain extent. When the reliability of the mechanical structure is low, the cost of the entire installation process is high and the efficiency is low

With the deepening and large-scale installation of offshore wind turbines, higher lifting requirements are put forward for the boom, and the installation process of offshore wind turbines will be more challenging, making the construction difficulty and installation cost of offshore wind turbine installation equipment greatly increased , will eventually restrict the development of offshore wind power in China
