DGUV V3 Inspections at Meerwind Süd and Ost

A complex offshore asset

Located roughly 23 kilometres north of Helgoland, Meerwind Sud and Ost is one of Germany’s early large scale offshore wind farms. The project consists of 80 Siemens turbines with a combined capacity of 288 MW, spread across a wide offshore area and connected via an offshore transformer platform. [bg-verkehr.de]

Even under normal conditions, managing the integrity of this many assets is no small task. Offshore, however, everything becomes more demanding. Saltwater exposure, constant humidity, mechanical vibration and restricted access windows all accelerate wear and increase the importance of robust inspection regimes.

From a regulatory perspective, the operator needed to ensure full compliance with DGUV V3 requirements for electrical installations. At the same time, they wanted more than just compliance. They wanted insight into the actual condition of their assets.

Mobilisation from Helgoland

Mobilisation for the inspection campaign was carried out from Helgoland, which served as the logistical base for offshore operations. From there, personnel, tools and inspection equipment were transferred to the turbines using vessel transport aligned with daily weather windows. The proximity of Helgoland to the wind farm allowed for efficient transit times and flexible planning, enabling the teams to maximise productive hours offshore while maintaining strict safety and access procedures.

Cooperation with WindMW

The successful execution of the campaign relied on close cooperation with WindMW as the asset operator. Coordination on planning, turbine availability and offshore logistics ensured that inspection activities were seamlessly integrated into ongoing operations. Regular communication and alignment allowed for rapid decision-making when conditions changed, while the shared focus on safety and quality ensured that the inspections were completed efficiently without compromising operational performance.
