Construction of the Bothnia Wind Deep Quay 3

We are building a 173-metre-long Deep Pier 3 in the port of Raahe, as well as a new port field about 40 metres wide as part of the Bothnia Wind complex

A new 173-metre-long Deep Pier 3 and an approximately 40-metre-wide port field will be built in the Port of Raahe as part of the Bothnia Wind complex. In the future, the quay structure we have implemented is intended to serve jack-up vessels for offshore wind power projects, which will strengthen the position of the Port of Raahe as a key hub in the Finnish offshore wind industry.

The contract includes sliding castings, installations, dredging of demanding pier elements, as well as molding preparations for the edge beams. During the autumn and winter, we focus on molding, reinforcing and concreting works. The pier is implemented as a reinforced concrete corner support wall pier anchored to the background ground, where plate-like seam elements are installed between the load-bearing corner support wall elements.

The electrification work of the quay area, including the construction of the electrical room, is carried out in accordance with the electrical plans. In addition, the contract includes the water supply of the quay background, regional plans, as well as the profiling and paving of the previously built assembly area on the basis of separate plans. Our experience from previous projects has helped to ensure a smooth and high-quality implementation of this project as well. The project has also done deep sealing of the background field and filling.

Strong collaboration is the key to success

Customer cooperation has been open and constructive. We have been flexible in supporting the initial contract negotiations of the project and have kept to both the schedule and the budget. The customer has especially praised the planning and implementation of dredging and filling works, and communication has been smooth throughout the project.

Safety has been of paramount importance to us in the project. The work has been able to be carried out in a busy harbour environment safely and without disturbances to other traffic. The construction of the pier will significantly strengthen the technical capabilities of the port and promote Finland's transition towards cleaner energy production. We are committed to harnessing our expertise to improve the operating conditions of offshore wind power in Finland.

The project started in the spring of 2025 and will be completed in the autumn of 2026.
