Waller Marine, Inc. supports the marine salvage industry
with consulting services offering sometimes-unique
technical solutions to the salvage of vessels and drilling
rigs.
Support of the salvage industry and vessel owners also
includes the preparation of computer-based models of
barges and ships for load monitoring and to provide quick
response capability to owners and salvers to determine
vessel condition and solutions when a collision or sinking
event occurs.
Often Waller Marine is asked to perform a marine salvage operation itself, such as the recent repair and salvage in 2007 of the oil barge, DBL 152, which WMI undertook with it's own personnel as described below.
DBL 152 Project
Waller Marine recently completed the marine salvage operation
of the 160,000 bbl tank barge DBL 152 at a location in
the Port of Chickasaw, Alabama. The 20,000-dwt barge,
having dimensions of 442 feet in length, 76 feet beam
and 44 feet to the Trunk Deck, capsized in the Gulf of
Mexico as a result of the hull striking a submerged object
when fully loaded with bunker fuel.
Verde metals of Brownsville, Texas eventually purchased
the barge for salvage and possible reuse. After having
the oil removed and still in the overturned position, Waller
repaired the damaged tank tops and bottom shell plating
created by the accident and subsequent oil removal to
ABS survey, and proceeded to plan the up-righting of the
barge.
Salvage operations were based upon a complex
sequence of lifting the hull on air and simultaneous
ballasting and the positioning and attachment of
high holding-power anchors and powerful winches.
The barge was successfully rotated to a position
where the hull took a 90 degree angle to the water
and then dramatically rotated to the upright in the
confined slip in the Port of Chickasaw, Mobile,
Alabama.
