Waller Marine, Inc. announced the successful installation of its recently constructed floating power generation barges into a prepared
basin at Tacoa, Venezuela. The two 171 MW barges, each supporting a GE 7FA dual fuel industrial gas turbine, will quickly be
The basin will be closed from the ocean this week for the installation of two large structural caissons, each having dimensions of
115' long by 16' wide by 26 ' high and 450 tons, which will be positioned at the entrance of the basin to house the power barges.

"When we started this project, we always knew this would be a major undertaking and represent one of our most significant
challenges," stated David Waller, president of Waller Marine, Inc. "The successful completion of this project will allow an additional
1500 MW average capacity to meet power demands in Caracas."

For phase II of the project, Waller is also preparing two 180,000-barrel fuel storage barges, one fitted with a large reverse osmosis
plant, which will moor offshore Tacoa to supply diesel fuel and demineralized water to the floating power plant. It is proposed that
the diesel fuel systems will be substituted with gas in the near future by a floating LNG storage and regasification facility designed
and constructed by Waller Marine.

Waller Marine is forging new energy efficient initiatives to several countries with its gas to wire technologies that involve relatively
small scale floating natural gas liquefaction, regasification and storage systems, as well as, small capacity articulated tug barge
transport vessels with LNG fueled propulsion systems. These initiatives have opened up significant opportunities for countries and
areas of population to produce lower cost electrical power with simultaneous reduction in the emissions of greenhouse gases.

Waller Marine Finalizes Installation of Largest Floating Power Generation Barges in Venezuela (4.18.11)

Two 171 MW Floating Power Plants for Venezuela (10.10.10)
Waller Marine, Inc. of Houston, Texas has launched what will become the world's largest floating power generation facility when
installed at a designated site in Venezuela. The two power barges, which Waller had constructed at the Signal International Shipyard
in Orange, Texas, were transferred from their land based construction locations to the water in August 2010. The generation facility,
initially comprising two Floating Power Plants each installed with a single GE 7FA gas turbine generator, were then made ready for
ocean transport to Tacoa, Venezuela for installation in a prepared basin that will be protected from the sea. The completed plant will
generate much needed power to Caracas and surrounding areas.

This event culminates a Fast Track engineering, procurement and construction program undertaken by Waller to design, construct
and deliver the two power barges, each having an output of 171 MW (ISO), within a 180 day period. Constructed to approval and
survey of the marine classification society, The American Bureau of Shipping, each barge will represent the largest of it's kind in the
world. This first phase of the facility will surpass the capacity of the Waller-designed 220 MW combined cycle floating power plant
installed in India in 2001; currently the world's largest.

Waller is now in the early stages of engineering the
second phase of the construction program, a 260
MW steam cycle barge that will be fitted with heat
recovery steam generators and a 260 MW steam
turbine generator that will increase the total floating
generating facility capacity to 600 MW.

Additionally, Waller has engineered and constructed
a 360,000 barrel capacity floating fuel storage barge
equipped with an 800 gpm reverse osmosis plant to
provide fuel and demineralized water to the facility.

Waller Marine recently completed the 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
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

DBL 152 Project

The Cianbro Project is an innovation in the latest concept to
develop larger supply vessels for deep-water drilling rigs.  New
requirements demand that these ships have the capability to carry
a varied mix of supplies according to demand, and therefore be
classed to suit this multiple duty.

An important feature is the higher delivery speed provided by
multiple main engines.  This makes the distance to deep-water
rigs a smaller time problem.

The main deck of the ship forms the packaged cargo carrier and
the liquid is carried in the hull tanks, all of which are totally
isolated from the main hull.  This arrangement allows the ship
flexiblity in it's duty to be able to supply varying needs to the
different deep-water rigs.
