World Marine Offshore orders two Wavecraft at Umoe Mandal

World Marine Offshore orders Ørsted-bound crew transfer vessels from Umoe Mandal 28 April 2022 – Danish crew transfer vessel operator World Marine Offshore (WMO) has contracted Norwegian shipbuilder Umoe Mandal AS to build two second generation Wavecraft™ crew transfer vessels, plus entered into bareboat charter agreements for two similar vessels that are owned by the Umoe Group. Three of the four vessels will go on contract with Ørsted.
“Our Wavecraft vessels are unique as they are heave compensated and probably the most efficient crew transfer vessels in the world. They can transfer personnel in wave heights up to 2.5 metres and are capable of 40-45 knots service speed. World Marine Offshore (WMO) and Ørsted are the most experienced users of these air-cushioned catamarans. To receive further orders from the companies who are most familiar with this vessel type confirms their confidence in the vessels’ performance and quality,” says Tom Harald Svennevig, CEO of Umoe Mandal.

WMO has ordered two newbuild, second generation Wavecraft™ vessels of the Sprinter 28 design from Umoe Mandal. In addition, WMO has entered into four-year bareboat charter agreements for the two existing Wavecraft™ vessels Umoe Firmus and Umoe Rapid. The vessels’ owner, the Umoe Group, is Umoe Mandal’s majority shareholder.
Upon completion, the two newbuild vessels will enter service for Ørsted on wind farms located on UK’s east coast. Both vessels will be delivered from Umoe Mandal in 2023.
Air-cushioned catamaran

All Wavecraft™ vessels are based on an air-cushion catamaran design, which guarantees rapid transit time, excellent seakeeping and passenger comfort, superior fuel economy and reduced environmental footprint. They are built in composite sandwich materials that enables up to 20-30 percent lower fuel consumption than for example aluminium vessels, with associated reduced emission levels.

Further, Wavecraft™ crew transfer vessels are equipped with a unique boarding control system (BCS™) which eliminates wave motions and allows transfer of personnel to the offshore turbines in waves up to 2.5mHs, allowing large operational window for offshore wind farm operators.

“The combination of 40-45 knots operating speed and our boarding control system means that wind farm operators can get a substantially higher number of operating hours out of every offshore technician. Not only do we cut the transit and infield sailing time by half versus traditional CTVs, but we also increase the operating window significantly. With offshore wind farms moving further offshore, often in rougher seas, we believe the industry is ready for a new generation of high-performance crew transfer vessels,” adds Tom Harald Svennevig.

The Wavecraft™ vessels of the Sprinter 28 design is 27.5 metres long and 10.4 metres wide. It carries up to 24 passengers, plus four crew.
