AI Technical Summary

Technical Problem

Introducing large components into a wind turbine nacelle through a limited opening poses a risk of collision due to wind and wave conditions, especially in strong winds or open sea environments.

Method used

A guide tool with a first part attached to the nacelle and a second part attached to the component, featuring a wide entrance, narrow track, and tapered portion, guides the component through the opening by engaging protrusions to ensure precise positioning and minimize collisions.

Benefits of technology

The guide tool allows components to be accurately introduced into the nacelle without requiring precise positioning, reducing the risk of collisions by using a funnel-shaped design that adjusts for relative movements due to wind and wave conditions.

Abstract

A method for introducing a component (7) into the nacelle (6) of a wind turbine using a guide tool is disclosed. The guide tool includes a first part (1) attached to or near the upper opening (5) of the nacelle (6), and a second part (9) attached to or forming a part of the component (7) to be introduced. The first part (1) includes at least one guide portion (3) having a wide inlet (3a), a narrow track (3b), and a tapered portion (3c) connecting the wide inlet (3a) and the narrow track (3b), and the second part (9) includes at least one protruding portion (10). The part (7) is raised to a position above the nacelle (6), and then lowered while engaging at least one projection (10) of the second part (9) of the guide tool with the wide opening (3a) of at least one guide portion (3) of the first part (1) of the guide tool, and while guiding at least one projection (10) of the second part (9) of the guide tool along the tapered portion (3c) and the narrow track (3b) to position the part (7) relative to the nacelle (6).
