BRONAGH J - MOMA BARGE
Triton were contracted by a joint venture between
Bateman BV (Johannesburg Office) and Multiplex (Australian) to design,
what is described as a "Self Loading, Self Unloading, Self Propelled,
Manned Material Handling Barge" for the transport of Titanium
based raw products between a custom built 350m long conveyor jetty,
and an awaiting handi size bulk carrier, some 7 to 10 Nm off Moma
The Joint Venture is also developing the dune mine
and supplying the pond dredgers. The barge being but one part of their
The transhipment barge is classed ABS, and was built

The Material Handling Plant was designed by BMH (Sweden)
and integrated into the Triton designed barge.
The barge is equipped with self rendering, self tensioning
winches for holding alongside the jetty during loading and alongside
the ship during discharge. She is also equipped with 4 x 500 Kw 360deg
azimuth rudder propeller type HRP thrusters, controlled by a single
joystick control system.
Although the area is known for its calm weather,
most of the year, it is also a tropical cyclone zone, thus the barge
is equipped with a three point cyclone mooring system, to wait out
such a storm, whilst anchored away from the jetty.
All aspects of the barge design were performed by
Triton, including motion studies, mooring studies, powering calculations,
stability, finite element analysis and structural detailing. The electrical
and hydraulic design, being performed in consultation with Raubicon
and Basic, respectively.
