We reveal any issues that might be hidden beneath the water surface
The largest part of a wind turbine's foundation is hidden beneath the water surface or even buried in the seabed. Up to 95 percent of a wind farm's cables are not accessible for visual inspections. Yet both are crucial to a reliable operation of the wind farm, which is often for twenty-five years or longer. Deutsche Windtechnik has the operational equipment and experience needed to collect inspection data, and has furthermore the technical expertise to turn the collected data into conclusions and recommendations. The balance of system expertise is the key for our quality, and operational efficiency is the key for our commercial approach.

Integrity assessments comprise several steps:
Operational efficiency and cost optimisation are achieved using two methods:
Subsea services include inspection, integrity assessment and repair tasks.
Subsea visual inspections by ROV or similar cost-efficient technologies, both outside and inside the foundation, cover the inspection of:
Subsea maintenance and repair work includes:
An overview of our experience can be found in the reference overview.
Scour and seabed surveys include inspection, integrity assessment and repair tasks.
Scour and seabed surveys are carried out with proprietary multibeam echosounder equipment (MBES), which is installed on CTV (Crew Transfer Vessel)mobilised for survey applications. This CTV can be made available for simultaneous execution of other tasks, e.g. for logistical optimisation.
The applications include:
The surveys can be combined with subsea visual inspections to access further information, e.g. of cable free spans.
Repair activities can include:
