SeaRenergy acquires hemmerschütz Solutions GmbH and strengthens its position as a one-stop shop for the offshore wind industry
SeaRenergy Offshore Holding GmbH, a leading provider of specialized services for the offshore wind industry, has acquired 100 percent of the shares in hemmerschütz Solutions GmbH, effective 28 November 2025. With this acquisition, SeaRenergy further strengthens its service portfolio and sharpens its profile as an integrated one-stop shop for offshore wind projects.
With the hemmerschütz Solutions team, SeaRenergy welcomes highly experienced industry professionals with strong practical expertise in offshore maintenance and repair. This enables the company to complement its established offerings in engineering, marine services, QHSE and offshore experts with the direct execution of repair and maintenance measures with qualified inhouse resources.
The transaction not only strengthens the competitiveness and credibility of SeaRenergy’s offerings but also increases the company’s relevance throughout all project phases. By insourcing key services such as corrosion protection, welding, concrete repairs and services on rotor, tower and foundation, this acquisition strategically strengthens SeaRenergy’s ability to deliver a more integrated service offering, combining BoP, O&M and corrosion protection services for all stakeholders of the industry along the entire lifecycle of a project.
In addition, the expanded portfolio enhances SeaRenergy’s resilience against project cycle fluctuations, as demand for repair and maintenance services in offshore wind farms remains consistently high, even during periods of reduced new-build activity and underscores our commitment to the strategic expansion of our business areas in line with our Vision 2030.
“With the integration of hemmerschütz Solutions, we significantly increase our depth of value creation and further strengthen our role as a long-term partner to our clients.”, says Dr. Benjamin Vordemfelde, CEO of SeaRenergy. “Moreover, we are broadening and future-proofing our business while creating new project and development opportunities for SeaRenergy and hemmerschütz Solutions,” Dr. Benjamin Vordemfelde adds. “At the same time, we are increasing SeaRenergy’s attractiveness as an employer in a growing and highly dynamic market.”
As part of SeaRenergy, hemmerschütz Solutions gains access to new markets, larger offshore wind projects and long-term customer relationships, while continuing to contribute its core strengths in corrosion protection, welding technology and rotor blade services.
“Becoming part of SeaRenergy allows us to further develop our business while building on our hands-on expertise,” says Mark Thomaschütz, Managing Director of hemmerschütz Solutions. “Our services will remain clearly identifiable, while being embedded in integrated solutions jointly planned and delivered with SeaRenergy. This provides our team with a strong organizational foundation and the opportunity to work on even more complex offshore wind projects.”
The integration of the new subsidiary into SeaRenergy will take place over the coming weeks.
