Shore Power Supply for Stena-Ferries in Gothenburg and Rotterdam

Clean, renewable electricity from onshore means that Swedish Shipping Company Stena Line’s vessels Stena Germanica and Stena Scandinavica could shut off their diesel generators during their stay at Port of Gothenburg since early 2011 onwards. This pioneering project has gained a lot of interest among shipowners, ports and power utilities all over Europe.
Now, after almost one year of tests, Stena expands their shore power supply activities also in the port of Rotterdam at its Stena Line terminal. Terminal operator Stena Line contracted ABB to provide the technology for its ferries in order to mitigate any negative impact of its operations on the local community and the environment. As part of the plan to cut its fleet’s fuel consumption, Stena Line invested in the complete electrical infrastructure needed to simultaneously power two vessels while berthed in Hoek van Holland.
The two Cavotec Alternative Maritime Power (AMP) systems at the Hoek van Holland Holland terminal are the result of close cooperation between Cavotec, Stena Line, ABB, the Port of Rotterdam Authority and the Dutch Ministry of Infrastructure. The systems enable the Stena ferries to switch off their engines whilst docked and connect to shore side electricity to power lighting, heating and food preparation.
One of the units is a cable dispenser system that enables the two freight ferries, the Stena Transit and Stena Transporter, which service the Killinghome UK route, to plug in to shore side power. The other is installed at the Stena passenger berth where the Stena Britannica and Stena Hollandica service the Harwich UK route.
“One important reason behind this interest is that we at ABB are pioneering a connection technology that converts 50 Hz – the standard AC frequency in Europe – to 60 Hz, which most vessels use as their system frequency, by the use of frequency converters. Furthermore, this is the largest shore-to-ship connection in terms of effect capacity in Europe ever so far,” said Ismir Fazlagic, product responsible for onshore connections at ABB.
The Gothenburg / Rotterdam solution can therefore, also from an international perspective, imply a large-scale breakthrough for environment-friendly shore-to-ship power supply.

Stena ferries are plugging into shore power to reduce fuel consumption and emissions

“The benefits are so obvious. As the diesel generators are shut off, CO2 emissions are reduced to zero when the electricity is generated from renewable sources like water, wind or solar power. During a 10-hour stay in port, the diesel generators of one single ship can produce 60 tons of carbon dioxide. In addition to this, onshore power supply means less noise in the port with surroundings and allows a more efficient maintenance of onboard equipment.
The investment will also improve the air quality considerably in the immediate vicinity of the terminal, according to the Port of Rotterdam Authority.
The installation of the shore-based power, which will be used by a total of four Stena Line vessels, was supported by the Port of Rotterdam Authority, the municipality of Rotterdam and the Ministry of Infrastructure and the Environment.
Around 300 shore-based power connections for inland shipping are located in Rotterdam city centre, including a special connection for river cruise vessels.
So far, there are no immediate plans for more connections for ocean shipping, due to the high costs involved; however, new and renovated quays have been prepared for shore-based power in the future.
