The first batch of caisson foundations for the world’s first energy island have been basically completed and

will be sent to the site soon.

The energy island planned to be built in the Belgian waters is called Princess Elisabeth Island. It will be built

by DEME and Jan De Nul. Construction will start in September 2023. The construction site will be located at

the offshore engineering base in Vlissingen, the Netherlands.

A total of 23 caissons are about to be completed this time, each of which is 57 meters long, 30 meters wide

and 30 meters high, and weighs about 22,000 tons. The construction period of a single caisson is about

3 months. These caissons will form the outermost ring of the energy island, and the interior will require

2.3 million cubic meters of sand, which will be sourced locally.

As offshore wind power moves farther and farther offshore, the construction costs of transmission lines and

the logistics and transportation costs of operation and maintenance are also getting higher and higher.

Therefore, in 2018, someone proposed the concept of energy island for the first time.

The North Sea in Europe is surrounded by developed countries and has unique geographical advantages.

The construction of artificial energy islands in the North Sea integrates multiple functions such as power

collection, AC and DC power transformation, transnational power transmission hubs, and operation bases,

solving all problems at once.
