The 39.5 meter long ship has a capacity of 251 passengers, reaches a speed of over 30 knots and will significantly reduce the impact of ship operations on the environment. The 'Vittorio Morace', built by the Spanish shipyard
The new member of the fleet, named after the founder of the shipping company, is the first of nine ferries that will operate between
The battery-electric part of the drive is used for locally emission-free driving in the harbour area and as a booster. CO2 emissions are reduced by the particularly efficient mtu Series 4000 diesel engines which can also run on the renewable diesel (HVO, hydrotreated vegetable oil). Its use can lower the CO2 footprint by up to 90 per cent. Furthermore, the comparatively low overall weight of both the engines and the hybrid drive system contributes to high vessel propulsion efficiency, thereby reducing fuel consumption and emissions.
No compromises on speed and range, yet environmentally friendly

The 31 ferries in the Liberty Lines fleet operate all year round, transporting more than three and a half million passengers on routes of up to 100 nautical miles. They not only serve as tourist excursion ships but are above all an important lifeline for many residents of the islands who have to commute regularly. The best known are the Aeolian Islands of Panarea, Stromboli, Vulcano, Alicudi, Filicudi, Lipari and Salina, which are UNESCO World Heritage Sites.
Automation and monitoring: mtu NautIQ Blue Vision NG and mtu NautIQ Foresight
All components are coordinated by the mtu NautIQ Blue Vision NG control and monitoring system. The complete propulsion systems of the first two ships will be monitored by the mtu NautIQ Foresight equipment health monitoring system. It collects data on the technical condition and analyses and stores it in order to improve the operational availability of the ship, reduce maintenance costs and lower fuel consumption and thus CO2 emissions.
Technical data mtu Hybrid PropulsionPacks for
Gearboxes: Reintjes WVSA-1542 hybrid-capable with clutchable PTO/PTIs for interfacing with Electric Machines
Electric Machines: 2 x Danfoss Editron EM-PMI375 T1100-2900 permanent magnet E-Machines. Providing in this case about 130 kW each of propulsion power, and when in charging mode up to about 260 kW each. By using variable speed electric motors, it allows the use of simple fixed pitch propellers for the vessel.
Generator Sets: 2 x 100 kWe variable-speed gensets, operating from 1000 - 2400 rpm, with lightweight PM generators
Batteries: 3 x 11 EST Green Orca 1050 Battery Packs (346 kWh total installed)
DC Switchboards (incl. DC power converters, circuit breakers, filters and protection equipment)
