INSTALLATION DETAILS
The following notable design features, energy-saving
measures, and latest sustainable technology systems
were installed.
Engines and heat recovery systems
Tier III compliant engines (CAT) were installed, thus
ensuring that engines’ NOx emission is limited in
accordance with international standards. Water to water
heat exchangers on the engine block and air to water
heat exchangers on the exhaust pipes ensure maximum
heat recovery — heat which will normally be rejected
to atmosphere.

Effluent plant pipes and pumps.
The new ice smelter installed.
But not only did the planning have to include
getting all the equipment and tools to the base, but
also bringing back the old system. Nothing could be
left behind.
This was quite a tough job, as only 25 people could
make the journey to the base and, between them, they
had to complete all the upgrades — electrical, HVAC,
wet services, and so on. As they could only stay for the
summer, the crew worked long days to get everything
done on time.

The heat recovery systems increased the typical engine/
system efficiency from ±35% to ±80%. The hot water
thus generated is circulated to fresh air fan coil units in
order to heat the base and is also used to heat domestic
hot water via heat exchangers. Vertically configured,
close coupled centrifugal pumps with integral speed
drives were installed to ensure optimum performance,
ease of maintenance, and better utilisation of the limited
plant room space.
Effluent system
The effluent collection system installed in the mid-1990s
was of the standard cistern and urinal type, with gravity
draining from the second-floor ablution facilities to
