08 Avr Euroports unveils Koverhar: a large-scale industrial hub for offshore wind in the Baltic

During the WindEurope Offshore Helsinki conference last week, Euroports presented the development of the port of Koverhar, located in the Port of Hanko area, Finland, as the next-generation industrial hub for Finland, Sweden and across the Baltic Sea.

The port of Koverhar is designed to address a key structural gap in the market: the lack of integrated, industrial-scale port infrastructure capable of supporting both fabrication and marshalling activities.

From marshalling port to industrial platform

Located in the Port of Hanko area in southern Finland, Koverhar is not being developed as a traditional marshalling port. The concept goes further — an integrated industrial platform capable of supporting fabrication, storage, sequencing, and direct load-out within a single location.

This shift matters. Conventional project logistics depend on multiple sites, multiple handoffs, and sequential scheduling that creates exposure to delays at every interface. Koverhar is designed to remove those interfaces by consolidating the supply chain into a single, controlled environment.

The result: a more standardized, repeatable, and reliable model — built to support not just one project, but successive projects across the region.

Infrastructure built for scale

The physical specifications at Koverhar reflect the demands of large-format offshore wind construction:

  • ~90 hectares of immediately available terminal space, with up to ~500 hectares of industrial reserve
  • Heavy-duty quays (≥20 t/m²) capable of supporting large foundation structures
  • Parallel capacity to accommodate multiple concurrent projects
  • The layout has been designed to enable direct component transfer via SPMTs (self-propelled modular transporters) from fabrication or storage areas to the quay, with flexible load-out configurations — side or back — depending on installation strategies.

Multi-technology capability: GBS and monopiles

Koverhar is designed to support both gravity-based foundations (GBS) and monopile supply chains.

  • For Gravity-based structures (GBS), the concept integrates on-site fabrication, including concrete production, casting, curing, and storage, directly connected to the quays. Typical units (~40m diameter, 10–12 kt) can be transferred without intermediate transport.
  • For monopiles, Koverhar supports storage, handling, pre-assembly, and sequencing operations at the scale required by large-scale project campaigns. The infrastructure is sized for current and near-future turbine generations

De-risking the supply chain

One of the most persistent challenges in offshore wind project development is the misalignment between industrial planning and port readiness. Projects that advance through permitting and procurement can stall when port availability cannot be confirmed — or when infrastructure investments required by the port become a separate negotiation.

Koverhar addresses this directly:

  • Ready-to-operate infrastructure, independent from future port development risks
  • Shared platform model, reducing upfront CAPEX for individual projects
  • Secured port access, enabling schedule commitments earlier in the project lifecycle

By providing certainty on port capacity from the outset, Koverhar allows developers, contractors, and manufacturers to plan industrial operations with greater confidence.

A strategic position in the baltic

Euroports already operates terminals across Finland — including Hanko, Pietarsaari, and Kemi — with established capabilities in offshore and onshore wind logistics. Koverhar extends that footprint with a purpose-built industrial hub positioned to serve the Finnish, Swedish, and broader Baltic markets.
