Current Projects
Cianbro 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.

DBL 152 Project

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 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

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 connected to the grid and soon supply much needed power to Caracas.

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.

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.

Two 171 MW Floating Power Plants for Venezuela (10.10.10)

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.

"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 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.
