Explore the full potential of offshore wind projects with one trusted partner

TÜV SÜD and Tractebel DOC Offshore GmbH are partnering to work towards a common goal: a carbon-neutral future. With our international, independent and multidisciplinary expertise, we provide integrated and customised inspection, certification and advisory services, alongside innovative solutions for your offshore wind projects. 

The challenges of leading Successful Offshore wind projects


Offshore wind energy is a crucial pillar of the energy transition. However, companies that want to benefit from the enormous potential of offshore wind energy require specialist skills to construct and operate projects in a maritime environment. The planning process, including geotechnical and geophysical surveys, as well as environmental studies, presents unique challenges and places high demands on the project team. In addition, each permitting process for offshore wind farms is individual, complex and challenging for different engineering disciplines.

Experience and expertise are undeniably essential to realising offshore wind projects successfully. In particular, the early involvement of testing, inspection and certification (TIC) and offshore experts can optimise project development, project planning, interfaces and logistical processes, as well as avoid additional costs, delays and failing approval processes during project execution.
