MSH sections for Walney Extension Offshore

Vallourec has recently received an order for 400 tons of MSH (Mannesmann Structural Hollow Sections) which will be used as basic structures for the anode cages constituting the corrosion protection system of the Walney Extension Offshore Wind Farm. The MSH sections will serve as basic structures for the corrosion protection system of the offshore wind park in the Irish Sea. Walney Extension is a project of DONG Energy UK in the Irish Sea comprising up to 90 turbines with a total capacity of up to 660 MW.

The MSH sections provided by Vallourec will serve to fix a set of sacrificial anodes which help slowing down the oxidation of the wind turbines’ metal surface. Prior to their final assembly the tubes will be bent to their specified shape by Kersten Europe. Bladt Industries, responsible for the anode cage assembly, is specialized in large-scale and highly complex steel structures including foundations and substructures for wind turbine projects.

Proven applications of MSH sections include boat landings, platforms, topsides, j-tubes and transition pieces. PREON® marine, an innovative proprietary wind turbine grounding system based on MSH sections, is currently in an advanced stage of development.
