RN/RM Divers Required for Scapa Flow Exped

Ex RUSTY MERGANSER is a Naval Service sub aqua diving expedition to Scapa Flow that will take place 6-15 Oct 2017 and will be run by staff from JSSADC. The former RN Loyal class fleet tender and now liveaboard diving boat, MV Valhalla, will provide the base for the duration of the expedition.

Scapa Flow is world famous for the quality of its wreck diving. This was created by the scuttling of the German High Seas fleet in 1919 and the sinking of a further 43 ships by the Admiralty during both world wars in an attempt to block the entrances. Undoubtedly it is the best wreck diving site in Europe.

Ex RUSTY MERGANSER will aim to dive all the major WW1 wrecks in Scapa Flow including the battleships Konig, Kronprinz Willhelm and Markgraf.

Due to drop outs there are places for two Royal Navy/Royal Marines divers.   The minimum qualification is experienced Sports Diver although Dive Leaders will be preferred due to the challenging diving.  Thepersonal contribution is a maximum of £450 although it is hoped to be less.

Testing of Breathing Gas

Many people will have seen the recent unfortunate incident where a number of school children have been hospitalised after a diving lesson and the subsequent urgent message from the HSE regarding breathing gas from Aqualogistics in Stockport.

The Diving Standards Team wish all service divers to be reminded about the importance of testing breathing gas in accordance with the standards in JSP319 and BRd2806(5).  Specifically the following should be complied with:

  • All breathing gas requires an annual laboratory test at a UKAS accredited lab to BS EN12021:2014.
  • Three monthly tests are also required to comply with  HSE DVIS No.9 (Rev. 1)
  • Non-service compressors need a before use test using the Factair F2235
  • Expeds and Branches should also remain vigilant and if any compressor maintenance is observed or divers report feeling ‘unwell’ then CNBA should be re-tested to confirm the quality of the gas before the start of any dive evolution

Recent expeds have also highlighted the following items in their PXRs which may help with transporting and using the Factair F2235:

  • Transport the FACTAIR F2235 as hand luggage and NOT hold luggage.
  • Print off a copy of the FACTAIR F2235 operating instructions from the FACTAIR website in case you are challenged on what the kit does
  • If you are transporting the FACTAIR F2235 through a ‘FRAGILE’ country and you feel the equipment might be challenged have the ‘purpose of the FACTAIR’ translated into the local language to ease security clearance.
  • When ‘testing’ CNBA in countries with high humidity remember to run the compressor for longer or have the owners change the filters if you are struggling to meet the ‘water content’ of the BS EN12021:2014.
  • Order enough DRAGER sampling tubes which are ‘in-date’ and keep them in a refrigerator if in hot climates.
  • The purpose of the 5 minute ‘run through’ at 2 bar prior to the test is to ensure all moisture has been removed.
  • You have more tolerance on ‘water vapour’ at a lower cylinder pressure (<200 bar 50mg/m3 or >200 bar 35mg/m3)

More information on gas testing is contained in BRd 2806(5) and Annex K has details of the Factair F2235

 




Cancellation of Asi 2017 Diving Season

Due to limitations with the Air Line of Communication (ALOC) to Ascension Island all diving expeditions have been cancelled until for 2017. RAFSAA are working hard with Ascension Island Base to ensure that they will resume in 2018.

Units are advised to continue to bid for slots through the normal process and more information will be forthcoming in due course.

 




Change of JSSADC Email Addresses

To reflect changes within the structure of the Royal Navy’s personnel area, all JSSADC email addresses have changed with effect 26 Jun.  The major change occurs near the beginning of the address and all email addresses have changed as follows:

  • Delete “NAVY PERS” and replace with “NAVY NPS” – thus NAVY PERS-JSSADC OIC has changed to NAVY NPS-JSSADC OIC.  This also applies to emails from the internet thus NAVYPERS[email protected] is now NAVYNPS[email protected]

We have also used the opportunity to abbreviate/amend the email addresses for the Equipment Manager (Des) and Course Clerk (Suzanne).  Their new email addresses are as follows:

It goes without saying that this change will result a dramatic improvement in our ability to deliver courses and training 🙂
