Delivered in November 2010 to the
engineering and construction company
McConnell Dowell for operations at Port
Hedland, this work boat and barge is an
example of a design realised by Alucraft
to facilitate coastal construction work.
The Alucraft 11.9-metre "barge" was
born some years ago following requests
from companies involved in civil works
building long jetties to be used for the
export of minerals and other commodities.
The problem these companies face is
moving the necessary workers around the
"work site" or jetty to perform their various
jobs, as well as bringing the workers
backwards and forwards from the camp to
the start of the jetty or to large steel barges.
Effectively, this makes Alucraft's smaller
barge both a commuter or sea taxi for
workers, as well as a work boat in which to
move some lighter equipment.
The vessel is 11.9 metres in length to
allow companies to use skippers with
She has a length at waterline of 10.7
metres and a beam of 3.3 metres
(excluding the fender) and a shallow
draught of just 0.4 metres. The "barge"
displaces 6.1 tonnes lightship and 9.5
tonnes fully loaded.
This particular barge is powered by twin
Doosan L066TI engines, each rated at
134kW at 2,200rpm, driving twin Castoldi
282 waterjets. She has a maximum speed of
27 knots and a bollard pull of 1.5 tonnes, a
fuel capacity of 600 litres and a range of
150 nautical miles.
She has a crew of two and can carry 12
passengers when built to Class 2D or 30
when classed 1E.
A few variations on the design are
available from Alucraft.
First, a flat bottom twin outboard
version for a stable platform in smooth
waters, and for ease of storing on dry land.
Second, a moderate V bottom for
choppier conditions, using a twin diesel/jet
configuration for added manoeuvrability
-- especially for situations where petrol
is not permitted on site and where diesel
is requested instead. A third version has
the same moderate V hull with outboards
to perform a similar job where petrol may
be allowed. This moderate V version can
also be adapted for landing craft use,
moorings servicing duties, rubbish disposal
and other work where a simple strong
barge is needed.
Alucraft also has a number of ocean and
river-going crew-type boats currently
operating in Australia as well as Indonesia
and Papua New Guinea, which perform
either the fast transfer of workers, or some
simple taxiing and light cargo work as the
vessel reviewed here.
