KENMARE WCP-B PLANT - E-PC
Triton were initially contracted by Aker Solutions,
then later by E-PC to design all of the floating structures, the strongback
structures, all the internal support stools, for the various high
load components for example the Surge Bin, various Sumps, Pipe Towers,
Pump Stools, Pipe Bases, etc, on the KENMARE WCP-B Plant.
The 21 pontoons. along with all of these additional
support structures were fabricated by SA Shipyards in Durban, to be
transported on barges to Moma, where they are being assembled, along
with the actual plant above.
During the design phase, E-PC would supply us with
applicable loads which we would apply either to local FE Models of
the affected support structures, or to the global FE model, nicknamed
"The Beast". The global finite element model, was an immensly
large all encompassing Finite Element model, that included all of
the structure of all 21 pontoons, all the strongbacks, all the support
plynths, all pump and deck equipment supports, in full 3D shell elements.
It also included an imported beam element model of the actual plant
structure (supplied by E-PC), so as to model the combined stiffness
of the floating structures, as tied into the plant above. Hence all
stresses within the support structure could be assessed, but equally
importantly all deflections would be transmitted into the plant. As
all marine people know, anything that floats, deflects, and these
deflections needed to be quantified to be considered in the plant
structures being supported.
Together with the complete structural design and
structural analysis of these aspects of the plant, Triton were also
contracted to perform all the buoyancy and stability calculations
associated with such a floating structure. Further to this we also
performed the mooring force calculations for sizing the winches and
sheave towers etc.
By the end of the project, the Triton delivery pack
consisted of some 146 construction drawings.
RBM - EXTENSION TO PLANT A - NEW PLANT E - HATCH
Triton were responsible for the buoyancy and stability
calculations for the extension project to Plant A, and all buoyancy,
freeboard and stability calculations during the actual design phase
of Plant E.
Triton were also contracted to perform the mooring
force calculations, for the sizing of mooring winches, emergency mooring,
for various client specified wind conditions.
We have also subsequently been contracted directly
by RBM to perform various weight, buoyancy and freeboard calculations
at various times, on RBM's request for various reasons.
MANDENA PLANT - HATCH
Again Triton were reponsible for the buoyancy, freeboard
and stability calculations, as well as the mooring studies for the
Madena Plant.
NAMDEB PLANT - ANGLO AMERICA
Triton were contracted to perform the structural
design for single pontoon, which was designed to be built in modules
and panels in Johannesburg and assembled onsite at Oranjemund. In
parallel with the structural design, would be the associated Buoyancy,
Freeboard and Stability calculations, using plant weights as supplied
by Anglo.
