18,000 kW Hybrid Ferry 15 minutes Battery Charge

Since a few days route between Rostock and the Danish Gedser is on service with new hybrid ferry “Berlin”. Owned and operated by Scandlines has recorded as low fuel consumption and noise service. It uses its diesel engine on the open sea, but in the run-in and run-out in the ports is toggled on exhaust-free battery.

Since May 23, 2016, “Berlin” that’s the name of the unit, travels on the 50 km long route between Rostock and the Danish Gedser. It is the first of two hybrid ferries that are built and deployed. Cost of the eco-ferry approach €140 millions. Exhaust in new ferry does not come out in the first 30 minutes after departure and when entering the port switches. Diesel ship is very quiet, with low emission and consumption.

Scandlines: The system save up to 15% emissions

The German Danish shipping company of Scandlines founded in 1872, has since 2013 hybrid ferries in operation, the first, which was equipped with a hybrid engine, “Prinsesse Benedikte“. three more ferries are traveling on the nearly 20 km long route Puttgarden-Rødby and were rebuilt in 2014.

According to own statements, Scandlines is worldwide the first ferry that used a hybrid propulsion system of such size that stores excess energy in batteries. The system, as Scandlines, was able to save up to 15% of CO2 emissions.

 

The system corresponds to about 600 hybrid cars and makes it possible to run on 8800 ton vessel for about 30 minutes without diesel fuel. Then the open sea is reached and the diesel engine assumes the drive. The motor works most effectively with an occupancy rate of 85-90%, but uses only 40 to 55% at a crossing. The excess energy is stored in batteries and used when needed.

Emission-free hybrid ferry between Puttgarden and Rødby charge battery in 15 minutes.

The new ferry “Berlin” has capacity of 18,000 kW and 22 knots (41 km/h) designed for the Rostock-Gedser route. By a greater capacity on the car decks carry up-to 300 passengers. Transported wihtout cars can handle even 1300 people. The sister ship “Copenhagen” expected to enter the service in the autumn. For a completely emission-free ferry service between Rostock and Gedser wait since 2009 when first sketches and business planes were made, says company spokeswoman Anette Ustrup Svendsen. “The next step is the completely emission-free ferry service on the line Puttgarden-Rødby with 100% battery power.”

For the next few years, Scandlines plans conversion of hybrid ferry plug-in system will be on close observation. On-board batteries could be recharged during the 15-minute stay of the ferry in the port of shore-side charging stations. It was an ambitious undertaking, but explains Anette Ustrup Svendsen, which political support was necessary to do with this project.

In Norway the “amps” as the world’s first electric ferry has started in may 2015 the line service in Sognefjord. She can carry 360 passengers and 120 cars exhaust with CO2-free technology. All drives in this case come from Siemens.
