Danfoss Power Solutions’ Editron division will power a new hybrid-electric buoy-laying vessel for Armement des Phares et Balises, the French government department responsible for signaling hazards and marking shipping routes along the French coast. The vessel will be used to maintain and replace navigation buoys around the island of Corsica.
In 2019, the Interministerial Committee for the Sea embarked on a series of measures aimed at decarbonizing its maritime industry. One of these measures is the decarbonisation of ship propulsion and on-board energy. The commissioning of the electric buoy-laying vessel by the Armament des Phares et Balises contributes to this sustainability objective since the vessel will allow fuel savings of 25% to 30% compared to conventional diesel-powered vessels.
ECCS Marine will carry out the design and integration of the electrical system of the 24-meter long vessel, while the Editron division will equip it with two electric motors powered by 150 kilowatt-hour batteries, allowing the boat to be propelled entirely electrically at the occasion. Additionally, the energy stored in the batteries can be used to boost the hotel load when more power is needed. This means that the power of the electric motor can be minimized when operating in generator mode, bringing efficiency benefits. To further minimize its environmental footprint, the ship will also use solar panels.
In addition to the Editron engines, the vessel will have two Volvo D16 IMO Tier 3 engines equipped with particulate filters driving two variable-pitch propellers. The ship will also be equipped with a 35-tonne crane and several winches to maneuver the buoys, as well as a dynamic positioning system allowing the Lighthouse and Beacon Armament crews to carry out missions with the greatest possible precision and safety.
Erno Tenhunen, Marine Director of Danfoss’ Editron Division, commented:
“Our Editron system is designed for any type of marine vessel, as its benefits – such as reduced fuel consumption, reduced emissions, design freedom and easy integration – are universal. It is particularly ideal for a work like this, because stringent space and weight requirements are no problem for the market-leading power density of our parallel hybrid drive system.
Peter Enjalbert, Project Engineer at ECCS said:
“The sweeper will regularly enter and leave ports and pass through the protected maritime areas of Corsica, so it was important that greenhouse gas emissions and noise pollution were kept to a minimum, which the Editron division was able to ensure with its propulsion system. . This project has demonstrated that a fully electrified maritime industry is within reach, so we hope this electric vessel will be the first of many for this fleet.
Merré and CIB shipyards are currently building the vessel at their two main production sites in Nort-Sur-Erdre and Brest, France. The ship is expected to be delivered in mid-2023.
