Installation vessels use shore-to-ship power in Esbjerg

Port Esbjerg has announced that for the first time, installation vessels from the offshore wind industry have just connected to its new shore-to-ship power unit. The vessels use power while they are docked,  providing savings on carbon emissions.

Since January, the installation vessels
SEA INSTALLER and SEA CHALLENGER have been able to connect to a newly established shore-to-ship power plant on the Gemini Quay at Port Esbjerg. They used the electricity to power their pumps, monitoring systems, ventilation, and crew welfare facilities – instead of using their own diesel generators – while docked at Port Esbjerg.

“The environmental benefits of having docked vessels connect to onshore power are entirely clear. That’s why we’re so excited to be able to offer this service to also the very large vessels and to see a growing interest among our

customers. We take it as confirmation that we should continue our concerted efforts and major investments in the green transition at the port of Esbjerg,” said Jesper Bank, CCO at Port Esbjerg.

A large vessel using onshore power instead of its generators that are powered by fossil fuel will reduce its carbon emissions when in port. Both CO2, NOx and SOx emissions will reduce. Moreover, the use of onshore power will reduce the noise from the vessels as their generators may be turned off when the vessels are docked.

The two shore-to-ship power units have a capacity of 500 amp each and are able to supply up to 11,000 kWh every 24 hours on the two cable outlets.


Port Esbjerg and Ørsted have entered an agreement on certified green power, so the shore-to-ship power units will benefit from offshore wind energy in Denmark. Following increased demand among customers, the Port of Esbjerg plans to install more shore-to-ship power units.
