IT Corporation, in co-operation with the
US Navy hired TMT to assist in salvage operations
of a beached vessel at Midway Island. The
vessel was lying close to shore and had become
filled with sand contaminated by the ship’s
cargo and fuel system. The Navy was interested
in working with a commercial contractor employing
new and innovative technology. TMT was selected
and provided a custom design for the Tornado
3 dredge, employing a 4 inch Eddy Pump, manually
operated underwater by Navy divers. Using
a 25-foot suction hose, the 4-inch Eddy Pump
successfully removed the contaminated sand
and pumped it to an on-shore storage facility
for treatment and disposal.
Conclusions:
TMT has the experience and capability to
provide cost effective custom solutions to
material handling and transport problems.
TMT’s modular equipment design
makes transport a straightforward operation.
The Tornado 3 was shipped from San Diego
to Midway Island with no problems.
Materials were removed with little turbidity
and divers were able to hold and operate
the equipment underwater with good visibility.
The use of a 25-foot suction hose connected
to the intake of the 4-inch Eddy Pump demonstrated
the capacity to operate the Eddy Pump with
no cavitation, despite severe pump suction
(NPSH) conditions.
Sand and other trash items were pumped
with little down time and high capacity.
