Credit London Array © courtesy of London Array OEG Offshore entered the wind power and renewables market in 2010, with a substantial contract award for the landmark London Array Offshore Wind Farm, in the Thames Estuary. A decade on, the company offers a combined portfolio of products and services to the clean energy sector including bespoke module builds, sale and rental of DNV certified containers and offshore aviation services. The £2.2 million order placed by Siemens Transmission and Distribution Ltd., for the London Array Offshore Wind Farm included the design and custom build of eighteen prefabricated modular Local Equipment Rooms (LER) to house specialist electrical distribution equipment along with workshop and emergency accommodation facilities. Siemens selected a modular approach as it allowed a fast and efficient platform build to meet the tight timescales for the project.
