AI Technical Summary

Technical Problem

The manufacturing, transportation and installation of semi-submersible wind turbine platforms face challenges, including complex towing operations, long-distance transportation and high costs. The existing triangular hull structure cannot be loaded efficiently, affecting transportation economy and stability.

Method used

A hull structure is designed, including approximately vertical buoyancy stability columns and horizontal floats, forming a triangular shape, with the third float lower than the first and second floats, allowing the hull structure to be loaded in an inclined posture, and improving loading efficiency by inserting the second hull structure between the first and second float structures.

Benefits of technology

More efficient transportation economy is achieved, more wind turbine platform structures can be loaded on the same transport ship, transportation costs are reduced, and the strength and stability of the structure are maintained.

Abstract

The invention relates to a hull structure for a semi-submersible wind platform, the hull structure comprising: first, second and third buoyant stability columns extending substantially in a vertical direction; elongated submerged first, second and third pontoon structures extending in a substantially horizontal direction; wherein the hull structure has a substantially triangular shape in a horizontal plane, the first, second and third pontoon structures forming the sides of the triangle; wherein the pontoon structures extend between and are connected to the lower parts of the columns; and wherein the third pontoon structure is arranged such that its upper surface is located in a horizontal direction at a lower level than the upper surfaces of the first and second pontoon structures. The invention also relates to a method of loading a set of hull structures of the above type onto a semi-submersible transport vessel, and to a marine vessel carrying a set of hull structures of the above type.
