What the buyer says
Trinity House (TH) holds the operation and maintenance responsibility for over 60 lighthouses around England, Wales, the Channel Islands and Gibraltar. These critical aids-to-navigation (AtoNs) include several Rock Tower lighthouses that require regular modernisation and ongoing maintenance. Accordingly, Trinity House would like to investigate the feasibility of utilising jack-up and floating assets to avoid repeated journeys to these remote locations by helicopter to mobilise personnel, equipment and tools. To support this investigation, it is important to have accurate bathymetric and topographic surveys of the surrounding area.
Procedure: Below threshold - open competition. Published 25 Aug 2026.
