It manages 2,193 wind turbine generators with a combined capacity of 3,199 MW and is ranked among the top two providers of main component exchange (MCE) services in the European offshore wind market. Its customer base spans offshore wind farm operators, project developers, and OEMs across the German and broader European North Sea market.

The company's service portfolio covers the full offshore wind asset lifecycle: scheduled and unscheduled maintenance, troubleshooting, up-tower repairs, retrofit campaigns, oil exchange, main component overhauling (MCO) at dedicated Emden workshops, main component exchange (MCE) using proprietary jack-up vessels, offshore substation (OSS) services, 24/7 monitoring, QHSE management, transport and logistics, consulting, and the WM-Akademie training platform offering GWO/DGUV/FISAT courses. Core technical infrastructure includes dedicated jack-up vessels (via Atheleon/Harren & Partner), a 450-ton heavy-lift crane on Emden's quay with direct North Sea access, specialized component storage facilities, a 24/7 monitoring center, and high-resolution 3D scanning for OSS condition assessment. The company maintains multibrand capability across Areva M5000, Siemens 3.6-120, Senvion 5M/6M, Bard 5.0, and Vestas/NEG Micon turbines and is certified to ISO 9001:2015, ISO 14001:2015, ISO 27001, and ISO 45001.
