OIS‑Conbit is led by a local management team based in Rostock, with long‑standing experience in the region and deep understanding of the offshore wind market in Northern Germany. Being close to clients, assets, and projects is central to how we operate. Local leadership ensures fast decision‑making, practical solutions, and strong relationships with regional stakeholders. This proximity supports continuity for existing clients and provides a stable foundation for future growth.

The management team from former OIS and ISC remains in place within OIS‑Conbit, ensuring that knowledge, experience, and established ways of working are retained. This continuity is essential to safeguarding the strengths that have been built over many years, particularly in electrical and hydraulic services for offshore wind. Clients and supply chain partners continue to work with familiar faces who understand their assets, expectations, and operating environment.
Heiko Seefeldt continues in his role as Geschäftsführer of OIS‑Conbit, a position he already fulfilled within OIS. Heiko brings valuable experience, deep technical understanding, and strong relationships with clients and supply chain partners. His leadership is characterised by openness, reliability, and a pragmatic offshore mindset. With a strong presence in Rostock, Heiko plays a key role in day‑to‑day operations and long‑term development of the company.
Heiko Seefeldt is supported by Daan van den Wildenberg, who is seconded from Conbit headquarters in the Netherlands. Daan works closely with the OIS and ISC teams on a daily basis, liaising between organisations and supporting alignment of processes, governance, and long‑term objectives. By shadowing Heiko, Daan helps ensure continuity while supporting the integration and future development of OIS‑Conbit.
The integration of OIS‑Conbit is further supported by Dave Montforts, a senior leader and former Managing Director of Conbit. His experience adds strategic oversight and guidance during the integration phase. Commercially, Bram van Oirschot supports the local commercial team, strengthening market positioning and driving commercial efforts in close cooperation with the Rostock‑based organisation.
Together, this management structure combines local strength with international experience. It ensures stability, continuity, and a clear long‑term direction, enabling OIS‑Conbit to create sustainable value for offshore wind clients now and in the future.
