Surface treatment

Challenge

Although both MHI Vestas Offshore Wind and Siemens Gamesa Renewable Energy produce large, painted steel elements that must be able to withstand standing in an offshore salt environment for 25 years, in some cases there was a difference in what surface treatment the two manufacturers gave the individual components.

Subcontractors therefore had to restructure their production depending on which manufacturer the components were to be delivered to.

At the same time, the subcontractors had to keep track of and train crew for two different internal procedures. There were also a number of examples of the two manufacturers each oversizing the specifications for an element assault treatment to be on the safe side.

Solution

The project partners developed a common standard for the surface treatment of the individual wind turbine components, which in future will reduce the cost price and oversizing. The solution optimized the work with surface treatment, so that the wind industry’s producers in future avoid incurring unnecessary costs for their suppliers.
