Boreas in Amsterdam

Offshore installation vessel Boreas arrives in the port of Amsterdam

03 April 2025

On Monday, March 10, the new offshore installation vessel from Dutch company Van Oord arrived at TMA Logistics in the Port of Amsterdam. To reach its destination, the massive vessel—175 meters long and 63 meters wide—had to navigate through the world’s largest sea lock in IJmuiden, an impressive sight. In Amsterdam, the final outfitting and commissioning work will be completed before the Boreas departs for its first offshore wind project. So far, the Boreas is the widest vessel to have passed through the IJmuiden Sea Lock.

Home base for offshore installation vessels

Thanks to the construction and commissioning of the IJmuiden Sea Lock, we are now able to accommodate new offshore installation vessels of this size. These increasingly large vessels are used to install and maintain offshore wind farms—essential to enabling the energy transition. With its strategic location relative to the North Sea, the Port of Amsterdam is a perfect base of operations. Port of Amsterdam considers it important to facilitate offshore installation vessels and, together with TMA Logistics, has a key partner in place to receive them.

About the Boreas

The Boreas is the largest offshore installation vessel of its kind. The ship measures 175 meters in length and 63 meters in width, and is equipped with a crane capable of lifting over 3,000 tons. With a boom height of 155 meters, the Boreas is specially designed to transport and install the latest generation of wind turbines and foundations. Four enormous legs, each 126 meters long, allow the vessel to jack itself up and operate in waters up to 70 meters deep. Thanks to these features, the Boreas is ideally suited for the installation of offshore wind turbines of up to 20 MW.

Sustainable maritime innovation

The Boreas is the first vessel of its kind capable of running on methanol, reducing its environmental footprint by more than 78%. In addition, advanced emission control technologies minimize NOx emissions, and a 6,000 kWh battery pack further reduces fuel consumption and emissions.
