New hi-tech protective covers for deck machinery are now
being utilised on Anzac class vessels in the Australian Navy.
The covers are already saving the United States Navy millions
of dollars per year in reduced maintenance costs and are now
available to commercial vessels looking to cut down on corrosion
Huge savings are possible in terms of reduced maintenance
time, extended periods between major equipment overhauls and
a reduction in replacement costs.
Australian Pump Industries, Australasian distributors for
Shield Technologies, are supplying custom-made protective
covers for exposed equipment on vessels such as windlasses,
electronic control boxes, RHIBs and search lights.
The product was developed by the US Navy as part of its
"Small Business Innovation" research project to find an effective
way to protect exposed assets from corrosion. The result was the
development of a unique cover material that prevents the
condensation that results in "greenhouse" effects of humidity
and temperature fluctuations under the cover.
The new covers, sold under the Envelop trademark, are
fabricated into a custom fit that, when placed over the equipment,
will absorb surface moisture and condensation. This keeps the
metal surface dry and prevents deterioration and corrosion.
The absorbed moisture evaporates out through the cover, but
water cannot penetrate the cover from the outside! These hi-tech
covers also create a corrosion free environment with a new
"vapour corrosion inhibitor (VCI)" which forms a layer on the
metal surface, preventing oxidisation.
"These unique new Envelop covers have proved popular with
Navy crews, virtually eliminating corrosion and reducing the
time spent on maintenance," said Aussie Pumps John Hales.

In a true spirit of international
co-operation, Japanese-engineered F100
Yamaha outboards have been fitted to
power New Zealand-built Stabicraft
boats for use by the Australian Customs
and Border Protection Service.
The contract called for the supply of
nine identical boats to protect Australian
shores from illegal importation of drugs
and illegal immigrants.
On a day-to-day basis, they will be
used for routine inshore patrols, and
border management in and around bays,
marinas and harbours. The boats will
be initially stationed around both major
city locations (Melbourne, Newcastle
Brisbane) as well as more remote (Weipa,
Cairns, Townsville) bays, rivers and
estuaries with limited offshore use. Since
the boats are supplied on heavy-duty
trailers, they can be re-located as and
when required to respond to changed
circumstances or threats.
Power for this essential work is
provided by the Yamaha F100 model, a
75kW four-stroke outboard noted for its
excellent power to weight ratio, low fuel
consumption and quiet operation.
"We selected Yamaha because
Stabicraft is a Yamaha dealer in New
Zealand and quite a number of our dealers
are also Yamaha dealers," Leeon Johnston
of Stabicraft said.
"The Customs work is all about
reliability and back up service. With
Yamaha's extensive dealer network, we are
confident that Customs will be well
The F100 model in twin installation
was determined by the Stabicraft designers
as being the optimum power option.
"We're delighted to be supporting
Stabicraft and Australian Customs with
our outboard engines," said Brett
Hampson, National Sales and Marketing
Manager for Yamaha outboards.
"This is demanding and important
work. Operating in isolated areas demands
efficient operation, absolute reliability and
economical use of fuel. The F100 fits the
bill on all counts."
Each of the Stabicraft 659 Supercab boats
is fitted with twin Yamaha F100 engines.
The Yamaha-powered boats will
be required to withstand the hard work
and regular use to which Australian
Customs will subject them. The Stabicraft
is widely recognised as a safe and
dependable craft that is more than
capable in a commercial environment.
According to Yamaha's Brett Hampson,
there is an ever-increasing demand for
engines that satisfy not only on-water
performance criteria, but also appropriate
"Employers in both government and in
the private sector are today mindful of
equipping their employees with outboard
engines that are quiet and low in
emission," Brett Hampson said.
"The Yamaha F100 fits the bill
perfectly as it is a very quiet engine and
being four-stroke, also has minimal
emissions. For a crew to be on-board an
Australian Customs Stabicraft boat for
hours on end, we have to be mindful of
the work environment in terms of noise
