Euroports has presented advanced plans for Koverhar, a large-scale offshore wind industrial hub in Finland, designed to support the growing demand for supply chain capacity in the Baltic Sea.
The plan for the Finnish offshore wind hub was unveiled last year, when Euroports signed a Letter of Intent (LoI) with the partners behind the Noatun offshore wind project to establish Koverhar Harbour in the Port of Hanko as a logistics hub for the construction of the Noatun North offshore wind farm, with an option to use the hub for Noatun South as well.
The company recently presented a detailed proposition for the offshore wind port at the Wind Offshore Helsinki conference.
Koverhar is being positioned as a marshalling and long-term industrial platform aimed at enabling a shift from project-by-project logistics to a more standardised and repeatable offshore wind supply chain.
According to the company, the site will offer around 90 hectares of immediately available terminal space, with the potential to expand to approximately 500 hectares of industrial reserve. The infrastructure will include heavy-duty quays with a load-bearing capacity of at least 20 tonnes per square metre and deep-water berths, allowing the facility to handle multiple offshore wind projects simultaneously.
The concept is designed to support both gravity-based foundations (GBS) and monopile supply chains. For GBS, Koverhar will integrate on-site fabrication, including concrete production, casting, curing, and storage, directly connected to the quays. Units of around 40 metres in diameter and weighing between 10,000 and 12,000 tonnes can be transferred without intermediate transport.
For monopiles, the hub will provide capabilities for storage, handling, pre-assembly, and sequencing, tailored to large-scale project requirements.
The layout has been developed to streamline industrial flows, with direct transfer of components via self-propelled modular transporters (SPMTs) from fabrication or storage areas to the quay. The facility will also support flexible load-out configurations, including both side and back loading, depending on installation strategies.
According to Euroports, the integrated setup is intended to reduce congestion, minimise double handling, and improve execution reliability. The company also highlighted the role of Koverhar as a de-risking solution for offshore wind developers, offering a ready-to-operate platform, shared infrastructure to reduce upfront capital expenditure, and improved schedule certainty through early access to port capacity.
