Success on the ocean has forever depended on experience and innovation – two key elements in the partnership between Volvo Penta and Danfoss Editron. Together we’re setting a course towards electromobility at sea.
Moving towards a more sustainable future at sea, Volvo Penta and Danfoss Editron are collaborating in a historic partnership to deliver fully integrated solutions and greater efficiency.
Two hybrid crew transfer vessels – MHO Asgard and MHO Apollo – from Volvo Penta and Danfoss Editron deliver increased energy efficiency and save up to 127 metric tons of CO2 over each vessel’s working life, compared to traditional diesel-powered vessels.
When the offshore support- and crew-transfer operator MHO-Co wanted to meet the growing demand for sustainable transportation between shore and wind farms, they chose an advanced hybrid-electric solution from Volvo Penta and Danfoss Editron.
Taking the marine sector to the next level, Volvo Penta and Danfoss Editron create advanced hybrid solutions for maximum uptime, efficiency, and maneuverability.
The unique MHO-Co hybrid system includes the first electric Volvo Penta IPS. Two of the four drivelines are powered by Volvo Penta D13 propulsion engines; and two drives are powered by Danfoss Editron electric machines, which are in turn powered by five Volvo Penta D8 variable speed gensets. A battery pack supports peak-shaving, plus operating in fully electric mode at low speed, and during long stationary periods.
The new hybrid vessels can operate in zero-emission electric mode for up to eight hours. The combination of electric plus fuel propulsion achieves a maximum speed of around 24 knots.
Another benefit of this system is the flexibility, which provides the option to switch between engines. This helps in maintenance scheduling, and improves efficiency and noise levels, for example with the choice of using only one small engine when idling in the wind park.
