Umweltuntersuchung Nördlich Borkum GmbH (UMBO)

Hamburg-based company, registered in 2013 and announced in 2014 as a joint venture of DONG Energy (now Ørsted), E.ON and Strabag, set up to carry out joint environmental monitoring for offshore wind farms in the 'Nördlich Borkum' cluster, an area of about 4,300 km² north of the East Frisian Islands in the German North Sea. It commissioned the cluster-wide monitoring of resting and migratory birds and marine mammals required under the BSH's StUK4 standard, with results reported for the cluster as a whole, and shared its data with the BSH and other developers in the area. Ørsted Germany is now its shareholder.
