Siemens and ESVAGT A/S recently announced the christenings of two purpose-built Service Operation Vessels (SOV’s) specifically engineered to service and maintain offshore wind power plants. According to company literature, the christenings demonstrate ESVAGT’s ongoing commitment to transfer their maritime vessel competencies from offshore oil and gas to the somewhat younger offshore wind industry.

While ESVAGT owns the service vessels, Siemens provides their proprietary BlueDriveTM propulsion system to reduce CO2 emissions and fuel consumption, as well as hydraulic systems to support the Amplemann active access gangway. The new vessels will purportedly revolutionize offshore wind service by increasing productivity, accelerating response times, and implementing advanced safety mechanisms that will allow turbine access in significant wave heights of up to 2.5 meters (8.2 ft), which is higher than the safety limits of traditional crew transfer vessels (CTV).

The recent investment in the purpose-built vessels reflects a global trend in the offshore wind industry to build wind facilities further offshore. The two recently-christened vessels will service the North Sea and Baltic Sea, while a third vessel will join the fleet in autumn 2016 and service wind facilities off the east coast of England.
