    AF Gruppen is a full-service provider of offshore wind foundations and has extensive experience delivering to the offshore wind market. With AF Miljøbase Vats, our dedicated port facility, we are strategically positioned for both fabrication and offshore installation.

    Fabrication of Foundations

    AF Gruppen has extensive experience in concrete work across buildings, industrial structures, bridges, quays, culverts, and foundations, as well as marine constructions. With over 900 skilled concrete workers, we possess broad expertise and hands-on experience in concrete construction. This enables us to offer tailored concrete foundation solutions for both floating and fixed-bottom offshore wind.

    AF Environmental Base

    AF Miljøbase Vats is a modern industrial site purpose-built for offshore installations and marine structures. Here, AF Gruppen offers fabrication of all types of fixed and floating offshore wind foundations in concrete.

    With a 182-meter-long deep-water quay, 23-meter depth at the quay, and quickly increasing sea depth, Vats is suitable for construction and wet storage of all types of offshore wind foundations, including the spar concept.

    The deep and wide fjord ensures unrestricted vessel access to the base, and with multiple loading and barge quays, the site is ideal for handling large components. AF Gruppen serves as the port authority.
