The ACA further argues that IFEP comes

into its own on larger vessels, such as

CVF, where the available space allows
a less compromising distribution of
equipments to maximise survivability,
achieve optimum weight distribution and
the opportunity to site the prime movers
in areas not necessarily deep in the ship.
This is particularly true of the positioning
of the GTAs on starboard sponsons well
above the waterline.
At the top level, the power requirement
for CVF is 109MWe in conditions from
-20°C to +38°C ambient air temperature, or
105MWe in conditions up to 45°C ambient

Nominations are invited for the 2008 RINA - Lloyds Register Educational Trust Ship Safety Awards.
Entries close 31st January 2009
The RINA- Lloyds Register Educational Trust Ship Safety Awards
recognise recent innovations or developments which have led to an improvement of safety at sea, or which
have the potential to do so.
Entries may be submitted directly by individuals or teams from universities and industry from any country, and
may cover design, construction, research, equipment or operations. Entries are judged on originality, quality of
design, feasibility of production and contribution to ship safety.
Members who are aware of recent work by a university, company or organisation which has or could lead to
an improvement in safety at sea are invited to nominate them for one of the Awards, giving brief details of the
achievement. The nominated university, company or organisation will then be invited to submit an entry.
There are separate categories for universities and industry. An Award of £1500 is made in each of the categories
and will be presented at the 2009 RINA Annual Dinner.
