The ferry’s Aurora and Tycho Brahe, originally built in 1991,were converted to battery power with 4160 kWh batteries on board each vessel. The scope of the project also included battery racks, ABB’s award-winning power distribution system Onboard DC Grid, as well as energy storage control systems. The ferries annually transfer more than to 7.4 million passengers and 1.9 million vehicles between Helsingør, Denmark, and Helsingborg, Sweden.

Yara Birkeland is the world’s ? rst autonomous, battery powered and zero-emission container vessel. Ready for launch in 2020 at the earliest, Yara Birkeland will gradually move from manned operation to fully autonomous opera- tion during its ? rst two years of operation. Yara and technol- ogy company Kongsberg have teamed up to build this game- changing vessel. Replacing 40,000 truck journeys a year, Yara

Birkeland will reduce NOx and CO2 emissions and improve road safety in a densely populated urban area in Norway.

The second project relates to nine vessels known as

Grimaldi Green 5th Generation (GG5G). Grimaldi is one of the world’s largest operators of Roll-on/ Roll-off (Ro-

Ro) and Roll-on/ Roll-off Passenger (Ro-Pax) vessels. The hybrid propulsion system delivered by Kongsberg includes supply and integration of shaft generators, frequency drives, energy management systems together with Leclan- ché battery systems. The GG5Gs will be the ? rst in a new series of hybrid Ro-Ro vessels using fossil fuel during navi- gation, with batteries providing a peak-shaving function and electricity in port.


In response to customer requests, ABB has ? lled the gap between the low and high-power range of Azipod propulsors with the launch of a new series available in 7.5-14.5MW. In addition to ferry and RoPax vessels, this power range will also be applicable for larger offshore con- struction vessels, midsize cruise ships and shuttle tankers.

With this expansion, the Azipod propulsion family now
