Divers Afloat on Surface After Dive
A recent incident involved two divers remaining on the surface of the water, undetected by topside support and left afloat for 55 minutes, which was 1 hour and 35 minutes after the divers had deployed.
A second dive team had been deployed before this first team of divers was back on deck.
Several primary deficiencies were identified:
- Divers did not carry whistles
- Safety Divers did not patrol back deck of vessel
- Safety Divers did not alert captain and crew when divers were overdue
- Divers’ plan was not communicated clearly to safety divers/ topside support
Secondary deficiencies identified:
- Divers did not use navigational aids to ensure a safe return to the mooring
- Divers chose to take extra gear (cameras) despite conditions
- Dives conducted in marginal conditions (strong current)
- Complete pre-dive conditions and briefing were not conducted
The divers were safely sighted within one minute of alarm being raised and were safely back aboard within 20 minutes of alarm.
- Remain diligent in conducting thorough pre-dive briefings and gear checks.
- Conduct safety assessment of site prior to each dive.
- Ensure all divers have safety gear appropriate for conditions and mission (including whistles, safety sausages, etc.) and that divers are not carrying extra gear in potentially challenging conditions.
- Ensure all personnel involved clearly understand expectations, roles and communication chain.
