Notice Information

Notice Title

ITT - CSM Demonstration Survey UID 218

Notice Description

The UK CSM Demonstration Survey is a major seabed survey that will take place in April-May 2026. It is a novel collaboration between public sector organisations to integrate respective survey activities under the umbrella of the UK Centre for Seabed Mapping (UK CSM). This tender is to commission suitably experienced marine archaeological geophysicists/surveyors to participate in the CSM Demonstration Survey on behalf of Historic England. The survey will be carried out aboard RV Cefas Endeavour. Survey operations will be carried out 24 hours; HE-commissioned geophysicists/surveyors will operate a single 12-hour shift. Accommodation and subsistence will be provided aboard. Options are being maintained for different survey areas to allow for weather. The survey vessel will mobilise at Lowestoft and demobilise at Falmouth. Crew change will occur at Lowestoft or Falmouth. Other than the crew change, the vessel is not expected to return to port during each leg of the survey. Historic England's requirement is for one geophysicist/surveyor to participate in each leg of the survey. Tenderers can bid for either one or for both survey legs. Historic England's preference is to commission one contractor to cover both legs but reserves the right to commission one contractor for each leg.
