Development Overview

The Triton Knoll Wind Farm is a 857 megawatt offshore wind farm currently under construction, 33km off the coast of Grimsby, Lincolnshire. Following our involvement with the Gwynt Y Môr Wind Farm Control Building at the Port of Mostyn, Flintshire, and the Operations and Maintenance Base at Harwich International Port, we were approached by Innogy to design a similar facility at the Royal Dock in Grimsby.

Triton Knoll is a state-of-the-art offshore wind farm and is the largest Innogy currently have under construction. Once fully operational, it will be capable of generating enough renewable energy for the equivalent of over 800,000 typical UK households. The Operations and Maintenance facility has been designed to accommodate the 70 staff who will manage the long term operations of the offshore wind farm.

The new facility is split into two buildings to work around the constraints of a number of underground services. A 550m² single storey office building provides a Control Room, open plan offices, meeting rooms, change facilities, canteen and IT services, and sits alongside a 600m² double height warehouse building containing storage facilities, workshop area and hazmat store.

Ainsley Gommon provided Concept and Detailed design proposals supported by an NBS specification and room data sheets which allowed the scheme to be tendered on a Design and Build Contract. Main Contractor Tolent were appointed in June 2019 and construction works were completed twelve months later.
