Electric Drive


Crist Shipyards received yet another award for building a vehicle and passenger ferry equipped with an Electra drive. In June, the CEMT 2018 award for outstanding contribution to the success of European maritime industries went to the Gdynia-based company and to StoGda Ship Design & Engineering, the designer of the vessel. They received recognition for their contribution to constructing the first fully equipped vehicle and passenger ferry with an electric drive in the European Union.

In April, Elektra received the “Ship of the Year” award in the Marine Propulsion Awards contest.
P310 Elektra is a double-ended ferry 96 metres in length and 15 metres in width. It is equipped with a set of batteries with a lifetime of ca. 7 years. Charging will take place each time the ferry calls at port and last 5.6 minutes and a longer period 2 times a day. A set of 1040 kWh batteries allows the ferry to operate - under normal conditions - for one year without the need to use any other power source. However, due to difficult weather conditions prevalent in Finland during winter (including icing of reservoirs), the ferry is also equipped with (in addition to the batteries) a supplementary drive comprised of environmentally friendly diesel-electric engines. Furthermore, the vessel was fitted with a set of photovoltaic batteries on the front and back wall of the superstructure. The ferry sails between Nauvo and Parainen carrying 90 vehicles and 372 persons.

Furthermore, in the second half of the current year, Crist commissioned another vehicle and passenger ferry with an electric drive, NB70 Herjólfur, constructed for the Vegagerðin - Icelandic Road Transport Office. The vessel, 70 metres in length and 15 metres in width, was created to operate the route between Landeyjahöfn and Vestmannaeyjar, i.e. islands in the Westman archipelago located 9 km south of Iceland. It can accommodate 390 passengers in the winter period and up to 540 passengers in the summer period.

The Gdańsk-based Remontowa Shipbuilding is also engaged in constructing vessels with electric drives. Last year, it commissioned 2 double-ended ferries with hybrid drives ordered by Transport for London. Ben Woollacott and Dame Vera Lynn are already sailing as part of the public transport in England’s capital. Each one can accommodate 150 people and 45 passenger cars. They operate the Thames crossing connecting the districts of Woolwich and North Woolwich. The new ferries ensure 14% more space than the old ones, and hybrid drives guarantee increased fuel efficiency and reduced emissions.

The shipyard is also engaged in constructing 2 double-ended ferries with hybrid drives for Norled, one of the largest shipowners in Norway. The vessels will be 114.4 metres in length and 17.7 metres in width. They will be able to accommodate 296 passengers and 120 passenger cars. While operating normally, their power requirements will be satisfied by the pre-installed batteries charged when the ferry remains at berth, which usually lasts for ca. 11 minutes. For this reason, the vessels will be equipped with a fast charging system from the grid, which will be integrated with the automatic mooring system. They will operate the Festøya-Solavågen route.
