Founded in 2014 by Sebastian Onken, with a background at leading cable manufacturers, OOC has grown from a one-man engineering firm into a trusted partner for the offshore wind industry. As a highly specialized engineering company, we combine technical excellence with a level of customer service rarely found in larger organizations—an approach that has earned us contracts with leading renewable energy developers across Europe.

Headquartered in Nordenham, Germany, our facilities, conference rooms, offices, a dedicated jointing training center, and in-house storage. With 12.000 m² of open space for container storage, we are fully equipped to support complex projects.
