2019 JS Diving Safety Conference

This year’s JS Diving Safety Conference was attended by approximately 50 people and took place at HMS RALEIGH in Torpoint.

After the initial welcome brief and introduction, we were treated to a presentation by Ginge Crook, JSSADC Chief Instructor, on the work done to understand the wreck of HMS Coronation. This was followed by the new National Diving Officer, Dai Atkins, bringing us up to speed with BSAC developments.

Following a short break, it was Fran Hockley standing in at short notice to cover Tom Hughes’ slot which he was unable to fill due to illness. Fran’s presentation was on the excellent recreational and technical diving to be found in Croatia which is only a short flight from the UK.

The last of the morning sessions was filled by Jim Watson, BSAC Safety Manager, who delivered the annual summary of diving incidents. As there was no DO’s conference in 2018 this was new to the majority of people present.

After lunch, we welcomed Nick Reed from the Isle of Purbeck Sub Aqua Club (IPSAC) who delivered a fascinating presentation on Project Valentine 75. This is the research that the club have carried out to survey the 7 Valentine DD tanks that sank near Swanage in 1944 whilst rehearsing for the D-Day landings.

The last presentation was given by the newly re-titled Superintendent of Defence Diving (SODD), Cdr Don Crosbie, who provided an update on changes to his organisation. He also explained how there were likely to be further changes to the Diving Regulations which it was hoped would address some the current shortcomings. Probably of most interest were the plans to support off-duty diving whilst allowing military personnel to use service provided equipment. Further details on this to follow later in the year!

As the conference drew to a close there was the usual Q&A session for members of the JSSADPAC which took place in a good humoured and constructive fashion. The very last item was a wrap up from Cdr Sean Winkle and a presentation to SODD who will shortly depart on posting.

Next year’s conference will be on 18 March 2020 so please save the date!




Immersionary Pulmonary Oedema (IPO) – INM Guidance

Knowledge of Immersionary Pulmonary Oedema has been increasing in recent years. The Institute of Naval Medicine (INM) has published the following information that all divers should be aware of:

  • IPO is a life-threatening condition that can develop during a dive and all divers should be aware of the potential for this to affect them
  • In IPO fluid accumulates in the lung tissues leading to shortness of breath, coughing up of sputum, and/or chest pain
  • The risk is increased in people with high blood pressure, over-hydrating before a dive, diving in cold water, exertion and breathing against a negative pressure when diving.
  • First aid measures include removal from the water, call the DDMO/Coastguard/Ambulance, sit the casualty upright, place them on 100% oxygen, take them to a warm place if possible or re-warm on site, do not give any fluids and prepare for evacuation to hospital.
  • If the symptoms occur during the dive, the casualty should be closely accompanied to the surface
  • Consider IPO in anyone who reports equipment difficulties after a dive or switches to bail out due to perceived equipment difficulties
  • Do not dive again until medically assessed.
