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


8/47

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


9/47

This talk will look at 4 aspects of Hyperbaric Lifeboat

epoymen

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

HyperbaricLifeboat(HLB)

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?


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


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

.

You operate all over the world and transfer
