Cross-Baltic ferry operator Scandlines has selected Wärtsilä Marine, after a competitive tender process, to convert its two hybrid double-ender RoPax ferries Deutschland and Schleswig-Holstein to plug-in hybrid vessels. Wärtsilä Marine is a global leader in power, propulsion and lifecycle solutions for the marine industry.
Both Scandlines 15,187gt 1997-built ferries operate on the operators’ Fehmarn Belt link between Puttgarden (Germany) and Rødby (Denmark). The conversion project is costing EUR 31 million, with the German Ministry of Transport providing financial support via a funding programme covering sustainable modernisation of coastal vessels to reduce emissions. Funding is available covering up to 40% of the conversion costs.
The conversion of the two ferries is a key element in Scandlines goal to achieve emission-free operation on the route by 2030. The ferry operators’ overall vision is to realise zero emission operation on all routes by 2040.
The conversion project on the two sister ships involves replacing one diesel generator and existing systems on each vessel with a new shore-charged electrical system, including a high-energy storage system (ESS), rated at 5MWh. This will allow electricity to contribute approximately 80% of the energy needed for each crossing between Puttgarden and Rødby and back. Shore-charging facilities will be available in both ports, with charging of each ferry taking just twelve minutes.
Wärtsilä will engineer and deliver the hybrid convertors, the ESS and the Energy Management System, as well as the switching gears, transformers, the onboard shore charging system, and replacement components in the existing switchboard equipment.
In addition, Wärtsilä will also supervise the equipment installations, carry out the commissioning and provide preventive maintenance support services. All equipment and systems are scheduled for delivery summer 2025, with conversion work starting in the second half of 2025.
It has not yet been decided at which shipyard the conversions will be carried out.
