CWind has signed a charter contract agreement with Ørsted for a hybrid powered Surface Effect Ship (SES) to service the Borssele 1 and 2 offshore wind farms off the Dutch coast. To be delivered by mid-2020, the vessel is to support the project under an initial three-year firm charter with options available for a further two years.

The design includes the combination of electric and diesel propulsion which with the surface effect hull form and heave compensation technology. CWind claims this will allow it to operate in sea states of up to 2.0m Hs, whilst decreasing fuel burn and CO2.

The Hybrid SES crew transfer vessel was developed in partnership with ESNA, a ship design company based in Kristiansand, Norway. It will be built by Wight Shipyard Company and operate from the Dutch port of Vlissingen during its charter with Ørsted.

Ian Bryan, Managing Director, Group Business Operations said: “We are delighted to announce the agreement with Ørsted, and look forward to delivering the world’s first Hybrid SES for them in 2020. Our development of the vessel has been driven by listening to the market and our customers who want a greener, safer and more efficient Crew Transfer Vessel to support their commercial and green objectives.”

Naval architect and co-founder of ESNA, Trygve H. Espeland, also explains: “The vessel design will accommodate further developments in hybrid propulsion and battery technology, ensuring it has the capability of being developed into a totally carbon-free solution in the future”.

CWind stated that the Hybrid SES propulsion engine will deliver sprint speed and extreme bollard push, from its 1,300 kW installed diesel engines, which can be battery boosted up to 1,500 kW. It claims that this will lead to significant fuel savings through balancing engine and inefficient low engine power running hours, with battery drive modes including wind farm standby and low speed/harbour operations. This leads to engine operating hours being reduced by 50% during wind farm battery standby.
