To generate as much power as possible, Eneco plans to replace the ten windmills currently being used with nine more powerful turbines. “These generate twice as much power,” says Stefan van Doorn, project developer at Eneco. “The power generated by the windmills goes directly to the ships. In addition, the windmills also have a connection to the grid. The power from the windmills that the ships don’t use goes to the grid. If the wind is not strong enough, the ships can also access this power as back-up,” says Van Doorn.
Reduced noise pollution
A shore-side electricity installation is not only good for the environment, it’s also beneficial for local residents. “The usual generators on board are very large and make a lot of noise,” says Doedée. “They remain below the standard of 55 decibels, but the low-frequency noise is sometimes very high. It’s an engine that runs far in the background which can be experienced as a nuisance by some local residents.” In contrast, according to Van Doorn, the shore power installation is not silent, “but produces much less noise than an engine. Plus, the sound doesn’t carry as far as conventional engines.”
Shore power as a service
Shore power has several advantages for companies, crew, local residents, the environment and therefore for the port as a whole. Doedée: “I started this project about two years ago together with my colleague Erik van Hintum, a former captain. It soon became clear that the project not only offered opportunities for Heerema itself, but that it had a lot of potential to grow. After all, Heerema’s ships are not always moored in the harbor, so other ships would also be able to make use of the installation.”
Making quayside electricity accessible to a larger part of the port is also important to the Port Authority of Rotterdam and the municipality of Rotterdam. “It’s about quayside electricity as a service,” says Jarl Schoemaker, Senior Advisor of Environmental Management at the Port Authority. “If a company builds its own quayside electricity installation and then only uses it itself, it is often not profitable enough. But offering shore-side electricity in a commercial way such that other ships can also use the installation is financially interesting in the long term. It also inspires others to start using sustainable energy.”
Joint company formed
To be able to offer shore-side electricity as a service, Eneco and the Port Authority of Rotterdam set up a joint company. Shore Power BV will not only supply Heerema with shore-side electricity, it will also function as a shore-side electricity hub.
