General – Shore Power
Heerema Marine Contractors’ largest crane vessels, Sleipnir and Thialf have officially switched from using their engines to using Shore Power.

The successful commissioning of the Shore Power project is the result of a partnership between Eneco, the Port of Rotterdam Authority, and Heerema with the support of the Gemeente Rotterdam.
There is a global demand to reduce our impact on the planet and the partners involved in the Shore Power project are all dedicated to supporting the energy transition.
Shore Power enables vessels to switch off their engines and plug into the electrical grid for their energy supply. The connection built by Heerema, Eneco, and the Port of Rotterdam will supply Sleipnir and Thialf with sustainable energy that will originate from wind turbines located on the headland nearby or from another renewable source should it be required.
Koos-Jan van Brouwershaven, Heerema’s CEO said: “Heerema is committed to sustainability and we demonstrated this dedication by becoming Carbon Neutral in 2020. Each year from now to 2026 we have outlined our targeted emission reductions, and by plugging-in Shore Power we reduce our overall impact by 5%, equivalent to 5,000 diesel cars, which fulfills our first year’s target! We are looking forward to introducing more sustainability measures to continue this journey.”
The Shore Power connection has a 20 MW capacity, which is the energy equivalent of around 15,000 homes.
