DEWI-OCC Offshore and Certification Centre GmbH (DEWI-OCC) was founded in 2003 as a subsidiary of the German Wind Energy Institute (DEWI) with the city and the district of Cuxhaven as partners and is since then international successful.

Maritime competence and a special know-how in the field of wind energy represent the basis for the technical and scientific support of the growing offshore industry. For the wide variety of services offered by DEWI-OCC the interdisciplinary team of experienced and qualified engineers is prepared to meet all demands.

DEWI-OCC is a generally accepted certification body for on- and offshore wind turbines and their components, accredited by the DAP (Deutsches Akkreditierungssystem Prüfwesen). In the field of wind energy DEW-OCC carries out certifications as well as expertises for investors (due diligence) and for government authorities, type approvals, examinations, periodic inspections, risk- and damage analyses.

In Cuxhaven (North Germany) DEWI-OCC operates a test site for offshore prototypes. This location is predestined due to marine climate conditions and therefore allows the inshore testing of newly developed technologies.

DEWI-OCC supports the necessary knowledge- and technology transfer within scope of the designated wind farms at the European coast line. To consolidate international relations, DEWI-OCC participates in several research projects, is actively involved in the development of standards and sets high value on permanent education of the staff.
