Van Oord has been awarded two international offshore wind contracts with a combined value of more than EUR 500 million. The contracts are for the Baltic Power project in the Polish section of the Baltic Sea and the Greater Changhua 2b and 4 project in Taiwan.
The Baltic Power offshore wind farm is being developed by a joint venture between ORLEN (Poland) and Northland Power (Canada). The wind farm will be located in the Polish Exclusive Economic Zone of the Baltic Sea, 23 kilometres from shore. The wind farm will feature 76 wind turbines with a total capacity of 1.14 GW and will ultimately supply renewable energy to more than 1.5 million households in Poland. Baltic Power will be Poland’s first offshore wind farm and an important step in the country’s transition to renewable energy.
Van Oord will transport and install 78 foundations, 76 WTG foundations (each one consisting of a monopile and a transition piece), and an additional two foundations for offshore substations. To install the monopile foundations, Van Oord will deploy its heavy-lift installation vessel Svanen. The Svanen is specifically designed to cope with conditions in the Baltic Sea, including the challenging soil composition, and has proven its suitability on a large number of projects there, including Baltic 2, Arkona, Danish Kriegers Flak and Baltic Eagle.
The 76 transition pieces will be installed by a third-party DP installation vessel. The transport and installation of the foundations is scheduled to start in 2024 and is expected to be completed in summer 2025.
Greater Changhua 2b and 4
Like the Baltic Sea, Taiwan also has an ideal environment for developing offshore wind energy due to its geographical location and weather conditions. Van Oord recently signed on to the Greater Changhua 2b and 4 project. These wind farms are being constructed by Ørsted, 50 kilometres off the west coast of Taiwan. With a total capacity of 920 MW, they will supply renewable energy to approximately 1 million Taiwanese households per year.
Van Oord will be responsible for the transport and installation of three export cables, with a total length of approximately 175 kilometres. To transport and install the cables, Van Oord will deploy its dedicated cable-laying vessel Nexus. Van Oord’s own trencher Dig-It will bury the cables to the required depth. To pre-excavate cable joint pits down to the necessary burial depth, Van Oord will deploy its LNG-powered hopper dredger Vox Apolonia. The works are scheduled to start in 2024 and expected to be finished in 2025.
The Greater Changhua wind farms are familiar territory for Van Oord. Earlier this year, the company successfully completed the cable installation works at Greater Changhua 1 and 2a. Van Oord was responsible for the transport, installation and burial of the inter-array and export cables. All images: Van Oord
