    Brief

    Trinity House operates and maintains over 60 lighthouses across England, Wales, the Channel Islands, and Gibraltar. The organisation is seeking to improve accessibility to remote rock tower lighthouses (Smalls, Eddystone, and Les Hanois) by investigating the use of jack-up vessels and floating assets as alternatives to helicopter mobilisation for personnel, equipment, and tools. To support this feasibility study, Trinity House requires accurate bathymetric (seafloor depth and terrain) and topographic (land surface) surveys of the areas surrounding these three lighthouse locations. These surveys will provide essential data for assessing the viability of vessel-based access solutions. Key requirements: - Surveys must be completed by 31 March 2027 - Suppliers may submit bids for individual locations or multiple locations - Trinity House reserves the right to appoint one or multiple suppliers - Suppliers should provide separate cost quotes for each lighthouse location (Smalls, Eddystone, Les Hanois) This is an opportunity for surveying contractors with experience in hydrographic and topographic survey work in coastal and offshore environments.
