In 2009 the two main partners decided to team up and establish their own company after having worked together on numerous offshore projects since 2004. Prior to DOC both have successfully realized national and international projects such as OWF Burbo Bank (DONG), Interconnector NORNED (TenneT/Statnet) OWF Alpha Ventus (DOTI) and OWF Rødsand II (E.ON Sweden) for various installation and manufacturing companies.

At the same time a core team of employees with longstanding experience from the offshore wind sector was put together. They were immediately signed-up by well-established partners from the offshore wind industry. Simultaneously, DOC provided strategic support to various clients for establishing offshore business units.
Since its foundation DOC was able to develop the core team considerably, adding further competence by securing experienced experts for the various offshore works. Also, from the beginning DOC has been focusing on the training and development of young engineers for securing future demands and in-house competence. Health and safety for our employees comes first - no matter if on- or offshore. This is ensured by comprehensive trainings, first-class equipment and the compliance with workplace regulations. The entire team shall be committed to a sensitive handling of hazardous situations and shall contribute to avoiding such situations by conscientious and appropriate behavior.
