This vessel is an 80m, 4500 dead weight tonne ore transfer barge,
designed for Western Metals Limited. The vessel is operated by Carpentaria
Marine, on behalf of the owners, and has been in service since early
1997 transporting zinc and lead ores from the shallow water port of
Derby, to bulk carriers anchored in deep water in the adjacent King
Sound. |
 |
This dredger project involved the design and construction of two 40.75m
Bucketwheel dredgers. Dredging components were fabricated in Australia
by Neumann Equipment P/L. |
 |
This vessel is a 41.55 x 10.97m dumb barge, converted for use as a
floating container storage and transfer platform. The Gippsland can
take up to 18 twenty foot containers from the supply vessel, the Riverside
Cloud, and transfer these to a landing barge to be taken ashore. This
enables quicker delivery time by the supply vessel as it is not waiting
for smaller vessels to ferry cargo ashore. The Gippsland is equipped
with a 60 tonne crawler crane, for handling containers, and has a
genset to enable reefer containers to be kept on board. |
 |
The North Wind project involved the conversion of a split hopper barge
into a fixed hopper barge with an Hitachi EX300 hydraulic excavator
used to unload cargo. The North Wind is 52.4m x 10.7m, and carries
silica from North Stradbroke Island to Brisbane with a maximum cargo
capacity of 1225 tonnes. |

survey. |
