Grounding and Total Loss of Dive Support Vessel Jean Elaine — Saint Peter's Pool

A Certificate That Wasn't Valid

On the afternoon of 22 July 2024, the 68-year-old wooden dive support vessel Jean Elaine grounded in Saint Peter's Pool, Deer Sound, Orkney. It developed a severe port list, took on water, and was abandoned. All eight people on board — crew and a Heriot-Watt University dive team surveying seagrass for Project Seagrass — were uninjured. The vessel itself did not survive.

Jean Elaine was operating without a valid commercial certificate. It had been suspended in April 2024 after a survey found sprung and rotten hull planking — a structural finding, not a maintenance note. The skipper's RYA Yachtmaster Offshore certificate had also expired seven days before the accident. Heriot-Watt University had chartered Jean Elaine for 17 trips over 10 years and had never once formally verified either the vessel's certificate or the skipper's qualifications — relying instead on verbal assurance.

The Plan That Changed

The accident happened after an unplanned change to the diving programme. When the primary seagrass site proved unsuitable, the dive team decided to investigate Saint Peter's Pool instead — a location outside the approved project plan. No risk assessment was carried out for the change. The skipper, who had never navigated into the Pool before, followed the dive team's inflatable boat in using a Navionics app on a tablet — not an approved chart system, no waypoints plotted, no tidal calculations recorded.

Local Knowledge Only Covers the Routes You Know

The skipper had over 30 years' experience in Orkney waters and had never prepared a written passage plan — local knowledge had always been enough, on the routes he knew. Saint Peter's Pool wasn't one of them. As the tide fell, Jean Elaine couldn't refloat. It took on water and lost power. The poor condition of its hull planking almost certainly accelerated the flooding once it listed onto the seabed. The RNLI recovered everyone safely; Jean Elaine did not return.

Recommended Actions

No MAIB recommendations were made — the actions had already been taken by the time the report was published. Heriot-Watt University revised its certification verification procedures; Project Seagrass implemented similar checks; the MCA issued a Notice of Concern to the university; and the MAIB Chief Inspector wrote directly to Universities UK to share the lessons across the sector. The practical actions every organisation chartering a vessel should take from this case:

1. Build a positive verification step into every charter: require sight of the vessel's current certificate and the skipper's qualifications before any voyage — a document check, not a verbal assurance
2. Plan every passage in writing, including waypoints, hazardous areas and tidal predictions for the actual departure and return times
3. Treat any change of plan at sea as a new risk to be assessed before it's acted on — not a minor adjustment to the existing plan
4. Establish a clear communication protocol between the skipper and any embarked scientific or commercial team, so the skipper always knows what's actually being asked of the vessel
