BASF develops durable coating system for offshore wind turbine foundations

Master Builders Solutions, part of BASF’s Construction Chemicals division, has launched the first coating system to provide 25 years of maintenance-free protection for offshore and marine structures. PIF explores the features and benefits of their new MasterProtect 9000 protective coating system, which boasts advanced chemical, mechanical and hydrophobic resistance and high flexibility to withstand the demands of offshore environments.

Chemical process engineering at its best

MasterProtect 9000 was developed by Master Builders Solutions chemical process engineering experts during several years of research. The revolutionary coating system is based on a hard wearing, high-build hydrophobic PU membrane that provides extremely effective protection for two main critical areas of the offshore structure: the splash zone and the submerged part of the foundations.

Additional properties of the system are chemical and mechanical resistance and high flexibility. The hydrophobic properties protect the steel structure from the aggressive impact of seawater. The chemical and mechanical resistance of the product are fit to withstand severe attack by waves, abrasion and impacts, especially affecting the splash zone.

The high flexibility ensures that the barrier will not crack and will keep its integrity even after years of weathering, impact and vibrations. The combination of all these properties results in a consistent, reliable and highly durable protection against steel corrosion.

Reduced application time and cost

Another feat of this chemical process engineering breakthrough is that MasterProtect 9000 also helps to significantly reduce the application time and cost compared with the most common epoxy paint systems used in the market. In fact, the full system can be applied in just one day.

The rate at which the offshore jacket foundations are manufactured in series is strongly dependent on the application of the coating system. The fast curing times of the individual components of MasterProtect 9000 allow for a considerable increase in output of foundation structures during production.

The system has been tested by the accredited independent Fraunhofer institute in accordance with the international standards NORSOK M-501 and ISO 20340. Successful testing and certification have laid the foundations for recognition by classification and insurance bodies and acceptance by the offshore market.
