He took out six LNG engines – with batteries and electric motors

Norled gave Westcon Power and Automation a deal to rebuild an electric drive.

The renewal begins in August 2019 in a shipyard as close as possible to Oslo.

– We have not signed a contract yet. We do not want to travel by road and we want to do as close as possible, says Technical Director Sigwald Brevik in Norway to TU.

In eastern Norway, Horten Verft and Ward Brevik are closest.

"We can look at the other side of the fjord and Sweden," said Breivik.

Router and Norled reported at the end of October that the Ferries Nessodden will become electric in 2019. Now more details are ready.

Hull in the corpse

The rearrangement includes the removal of all LNG-related equipment, including the two 10-year-old Mitsubishi engines.

For the removal of large gas engines, the holes must be cut into the carcass. Each boat also has two smaller diesel generators. They are retained as reserves, but must be ready for biodiesel.

Norled expects that for renovation it will require up to two months of shipyards.

"All three ferries must be completely reconstructed by the end of 2019," said Breivik.

He says it is technically not difficult to switch to battery operation.

– Ferries are large, have enough space for batteries and work at a moderate speed. With seats for 560 passengers, they are very energy efficient already, said Breivik

Ferries were built in 2009 by Shantiers de la Atlantique in France.

The space released in the engine room must be filled with battery packs and electric and control systems from Westcon Power & Automation

"We will integrate our proprietary energy and energy management system" E-submersion "with existing automation systems and power systems of the ship," said Frode Scarra, Sales and Business Development Head of Westcon Power & Automation.

He says that 2 MWh ferries have enough battery capacity to cope with more non-refueling trips. There will be only loading the port 8-9 minutes in Oslo.

Smart charging

The charging power is up to a maximum of 4 MW. According to Shaker, they will hardly use the effect of macking very often. It may be too difficult for batteries and equipment.

"It's a matter of using charging and load levels as nicely as possible, so life expectancy is not worsened and safety is well looked after," said Shkar.

Westcon Power & Automation has not yet selected a battery supplier.

Cavotec has developed a new charging plug for this project. The merger should take place before, and not with towers, which are used for electric ferries in western Norway.

The charging plug is attached to the port and the coupling occurs when the limbs of the ferry and the seafront are locked together.

"It's elegant that as soon as the limb rises from the ramp, the charge is released. Ferga can go straight," says Sophus Gide-Dahl in Kavotz.

More collective agreements

"We have a bigger demand among three to four suppliers that have batteries approved by the Norwegian Maritime Directorate and DNV GL," says Scar.

He states that there is a major activity in electrification, with several ferry projects and a hybrid construction of several offshore vessels.

"So we combined the need for batteries for more projects and we require a total price of 25 MWh," said Chkar to TU.

CO2 reduction

Ferry "King", "Queen" and "Prince" carry about 2.7 million passengers annually between Aker Brig and Nessotteningen.

Although the natural gas climate is better than diesel, electrification of the ferries will help reduce CO2 emissions by 6,000 tonnes per year. Emissions and energy consumption are much larger than in other public transport.

The Zero Environment Organization is pleased that the three Nesodden Ferries become nuclear containers.

"Oslo's time as an ecological capital is good. Norway is the world leader in ships and marine solutions without exhaust fumes, and Oslo can be an exhibition for this in the European Environmental General Year 2019," said Marius Geerset, Zero Technology Manager.
