Home' Baird Maritime : August 2011 Contents New Zealand's Q-West Boat Builders has
just launched a 17-metre catamaran,
destined for a life of rubbish collection
in Sydney Harbour for New South Wales
Maritime's Environmental Services team.
It was commissioned early in May in
Wanganui and was delivered to Sydney in
The Environmental Services team cleans
the waters and foreshores of Sydney
Harbour and navigable waters of the
Parramatta and Lane Cove Rivers. This area
consists of 5,020 hectares and a combined
foreshore length of 270 kilometres.
The vessel was designed by One2three
Naval Architects, building on experience
with past vessels operated by NSW
Maritime to create a unique craft.
'ES-8' is powered by two Caterpillar C12
six-cylinder engines, each producing
339kW at 2,100rpm, and is capable of
travelling at 15 knots with a full load.
The vessel has a pivoting bow ramp that
is stowed across the foredeck. It can be
hydraulically lowered to below deck level
to allow crewmembers to access Sydney
Harbour beaches for cleaning.
The main deck has a moon pool
configured to take a rubbish collection
cage. The cage can collect up to two tonnes
of rubbish before being emptied into an
alloy scow also located on the main deck
forward of the moon pool. The scow is
designed to collect six tonnes of rubbish.
There is a three-tonne hydraulically
powered onboard crane on the main deck,
which is fitted with a hook making it
capable of lifting the loaded cage for
discharging the debris into the scow. It also
gives the boat the capacity to retrieve large
hazards such as trees, mooring piles and
wharf structure components that may have
fallen into the harbour.
A rubbish capturing water thrust jet
spray system is located forward between the
two hulls and is designed to cause a surface
flow of water pushing the debris aft down
the tunnel and into the rubbish cage. This is
especially useful for hard to get at places.
The foredeck has a fire monitor system
powered by the vessel's hydraulic system.
The fire monitor is used to wash rubbish off
and away from wall and piers to facilitate
collection via the waterjet spray.
The vessel will also be used for
supporting water traffic management at
major aquatic events, and is capable of
being deployed in oil spill response and fire
fighting scenarios, as it can deploy oil
booms from its large working deck and
support fire-fighting operations on shore.
