The following section
should
apply to cold weather locations.
Bourbon Offshore’s policy for the protection of personnel flying to and from
Bo
u
r
b
on Vessels
requires the
following actions:
1.
If necessary, all personnel will be provided with Thermal Insulating Garments (TIG) in addition to
transit suits. If a TIG has been issued, its use is compulsory at all times.
2.
Transit suits (Multifab ‘Style 459’ or similar) will be supplied to all personnel. These are coverall
style survival suits with latex bellows neck seal, separate neoprene balaclava hood, and cross-body
zip. Throughout the flight, passengers
should
keep their fully zipped-up but need not don hoods
before take-off and landing.
An important parameter with a significant effect on the thermal efficiency of a helicopter suit is the rate of
water intake. Entry of water into the suit causes a significant loss of body heat as the organism tries to
warming cold water up to normal blood temperature. The main criteria for selecting the chosen suit model is
that it features a permanent neck seal that prevent water.
The thermal efficiency of a helicopter suit also depends on the type of clothing worn under it. The TIG lining
considerably improves thermal efficiency and increases the chance and time of survival of passengers in
the water in a ditching or crash landing but only if warm clothing is worn under the TIG.
In this respect the importance of layering
should
be underlined. Several layers of warm clothing provide
greater protection against the cold than one or two thick layers. To illustrate this principle, the individuals
who took part in the immersion endurance tests carried out at RGIT wore cotton vests, cotton shirts and
jumpers, cotton trousers, socks and training shoes. Bourbon Offshore strongly recommends layering.
