Embodiment Construction

[0038] Reference will now be made in detail to the exemplary embodiments, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, the same numerals in different drawings refer to the same or similar elements unless otherwise indicated. The implementations described in the following exemplary examples do not represent all implementations consistent with the present invention. Rather, they are merely examples of apparatuses and methods consistent with aspects of the invention as recited in the appended claims.

[0039] The jack-up platform impeller crane is currently the main hoisting method for domestic offshore wind turbines. Due to the limitations of swells, tides, and auxiliary ships, conventional methods cannot complete the transfer, assembly, and hoisting of the entire set of wind turbine equipment at one time. During this period, two Second positioning barge positioning and third blade transport ...

Abstract

The invention provides a rapid impeller hoisting method for an offshore wind power self-elevating platform ship. The rapid impeller hoisting method comprises the following steps that 1, the hoisting self-elevating platform ship, a hub elephant leg tool and a hub are sequentially placed in place, and a positioning barge and a blade transport ship are parked; 2, a first blade, a second blade and a third blade are sequentially hoisted in place through a time stitch method; and 3, hoisting of the wind wheel in place is completed, and finally hoisting of an impeller is completed. According to the method, only one-time positioning barge positioning and one-time blade transport ship barge approaching are needed, good practicability and effectiveness are achieved, the influences of tidal water, the flow direction and surges on hoisting operation are greatly reduced, the ship machine efficiency is improved, the hoisting profit rate is increased, and the offshore wind power construction progress is accelerated.

Description

technical field [0001] The invention belongs to the technical field of installation of offshore wind power generation, and in particular relates to a fast impeller hoisting method of an offshore wind power self-elevating platform ship. Background technique [0002] At present, domestic offshore wind turbine hoisting equipment is mainly jack-up platform ships. The deck area of ​​this batch of jack-up platform ships is limited, and it is impossible to complete the transfer, assembly, and hoisting procedures of the entire set of wind turbine equipment at one time; and the offshore construction window period is short. , often due to the restrictions of swells, tides and auxiliary ships, the operation period is affected. [0003] Taking the fast impeller crane of an offshore wind power self-elevating platform ship as an example, it takes 24 hours from the lifting of the first blade to the completion of the wind turbine hoisting without considering the surge. The specific hoisting...
