BASF's new, highly durable coating system for offshore wind turbine foundations

25 November 2019

BASF’s Master Builders Solutions® has launched MasterProtect 9000, the first coating system that ensures 25 years of maintenance-free protection for offshore and marine structures.

The official launch event took place on November 6-7, 2019 in Bremen, Germany.

During the two-day event, a large group of customers and key players in the global wind industry attended presentations and live demonstrations, showing great interest in the first-class performance of the system.

MasterProtect 9000 was developed by the Master Builders Solutions laboratory 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.

Furthermore, MasterProtect 9000 helps in significantly reducing the application time and cost compared with the most common epoxy paint systems used in the market, as the full system can be applied in only 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.
