Van Oord has successfully installed all 111 monopiles for the Baltica II wind farm in the Baltic Sea off Poland.
The 111 installed monopiles include 107 for wind turbines and four for offshore substations. Van Oord said the project was delivered safely and on schedule.
Baltica II is a 1.5GW offshore wind farm jointly developed by PGE and Ørsted. Van Oord said that once operational, it will generate enough renewable electricity to power around 2.5 million Polish households.
Van Oord served as the main contractor for the transport and installation of the Baltica II foundations and scour protection.
Before the work began, the Baltica II project team conducted a detailed analysis of different delivery options and potential scenarios that could affect the installation process.
Van Oord said the preparations drew on Ørsted’s experience in delivering offshore wind projects across multiple markets. This enabled the Baltica II project team to develop solutions designed to minimise key risks related to factors including the installation sequence, the availability of components and installation vessels, logistics, and the coordination of offshore activities.
The Baltica II monopiles are up to 100 metres long, between 9.5 and 10.5 metres in diameter, and weigh approximately 1,900 tonnes each.
Van Oord deployed the installation vessels Svanen and Aeolus for the project.
