    Brief

    Trinity House operates and maintains over 60 lighthouses across England, Wales, the Channel Islands, and Gibraltar. Several remote rock tower lighthouses require regular modernization and maintenance. To reduce costly helicopter mobilizations for personnel, equipment, and tools, Trinity House is investigating the use of jack-up vessels and floating assets for access. This opportunity seeks accurate bathymetric (seabed depth and features) and topographic (surface terrain) surveys of the areas surrounding Bishop Rock and Longships Lighthouses. Survey data will inform the feasibility of alternative vessel-based access methods to improve operational efficiency and reduce costs. Qualified suppliers should have experience in marine surveying, hydrographic data collection, and working in challenging offshore environments.
