To have a Hyperbaric Reception Facility or not?
At the 2009 IMCA Conference in Rio:
considering all aspects of the Planned evacuation was:
us a eren p ace o eep e o es .
IMO requires a 72 hour survival capability for ALL personnel so do we
design HLB systems to support just 72 hours
Is this appropriate for diving? eg decompression from 150msw is 150hours approx
7/30/2019 Hyperbaric Lifeboat

To have a Hyperbaric Reception Facility or not?
72 hours - as a
MINIMUM in
be far worse thanthese
ven decompression from typical working depths of say 150msw is 150 hourspprox
is therefore acknowledged that in most saturation diving we will require
ccess to a Hyperbaric Reception Facility

1. Hyperbaric Reception and Recovery facilities
2. HLB recover trans ort interfacin and matin
3. The impact of the new generation of larger HLBs
4. Medical Support relating to HLBs

Reception
The previous belief by the industry is that we have HLB reception plans
in place and that it is quite a straightforward job
Following a detailed review of equipment and,could successfully recover and decompress divers
Why do we have these doubts?
7/30/2019 Hyperbaric Lifeboat
16/47
HyperbaricLifeboat(HLB)Recovery
Recovery of the HLB from the sea is probably only possible with a
specialised vessel such as the Havila Trol l
Only Norway has these vessels
7/30/2019 Hyperbaric Lifeboat
17/47
HyperbaricLifeboat(HLB)Recovery
It is highly unlikely that the HLB wil l be lifted from
the sea by crane onto the deck of another vessel.
Problems wil l be sea state, snatch loadings,
attachment of lif ting equipment etc
What are the options?
rapidly deployable recovery system an economicalTroll
This system could be stored either on a suitable
vessel on site, or at a base depending upon
