Problems solved by technology

[0004] The main purpose of the present invention is to provide a method for installing an offshore platform to solve the problem that in the prior art, the offshore platform adopts the float-over installation method, which has transportation risks and cannot be installed, while the float-over installation method requires relatively high rental costs for installation equipment. Problems that lead to high installation costs

Abstract

The invention provides an installation method of an offshore platform. The installation method of the offshore platform comprises the step of installing a platform base, the step of transporting the offshore platform and the step of enabling the offshore platform to be butted with the platform base, wherein before the step of transporting, the step of lowering the offshore platform is included, sothat the gravity of the offshore platform is reduced during the transporting process; and after the step of butting, the step of lifting the offshore platform is further included so as to lift the platform body to the working height. The installation method of the offshore platform has the benefits as follows: on the basis of the float-over installation method and by lowering the platform body ofthe offshore platform through the built-in lifting device of the offshore platform before the step of transporting, transportation risks are reduced without increasing the size of a ship, and after the butting step of the offshore platform is completed, the platform body is lifted by the lifting device to the working height, the normal operation of the offshore platform is ensured, and the installation cost is reduced due to that no large-sized lifting equipment is needed.

Description

technical field [0001] The invention relates to the technical field of offshore platform installation, in particular to an offshore platform installation method. Background technique [0002] At present, there are two main installation methods for offshore wind power generation and transmission platforms: one is the hoisting installation method, which uses a crane installed on a barge to lift the top structure of the offshore platform and install it on the platform foundation that has been installed in advance. The other is the float-over installation method, which uses a semi-submersible vessel to transport the top platform to the offshore installation site. After the alignment work is completed, the ship sinks vertically by increasing the tonnage of the loaded water, so that the top structure is placed on the platform base. After the top structure and the platform base are connected and fixed, the ship drives away from the platform base , to complete the installation of t...
