YORKSHIRE, UK – Danish shipbuilder and operator MHO-Co has contracted Danfoss Editron to deliver the drivetrain systems that will power what are said to be the UK’s first two hybrid crew transfer vessels (CTVs).
The CTVs will serve Ørsted’s Hornsea Two offshore wind farm, which will be about 55 mi (89 km) off the Yorkshire coast in the North Sea. It is expected to enter operation in 2022.
Both vessels will be equipped with a Danfoss Editron serial hybrid system consisting of four propulsion motors. The systems will also include DC-DC converters for the vessels’ batteries. The company said both CTVs, which will be capable of operating in either fully-electric or hybrid mode, will save about 127 metric tons of CO2 compared to traditional diesel-powered vessels.
The 35-m (82-ft) CTVs will both be capable of carrying 24 passengers and will be fitted with a large lounge area and eight cabins.
They will also have the possibility of featuring an access system on the front deck, allowing for the transfer of up to six people and cargo to offshore structures. This will eliminate climbing, increase workability, and reduce the transfer time from vessel to offshore structure.
The vessels are due to be delivered in 2Q 2021.
Erno Tenhunen, Danfoss Editron’s Marine Director, said: “Our EDITRON system can easily place all hybrid propulsion components into a limited space, plus allows flexibility on battery selection, system concepts and machinery room design.”
