Waller Marine Inc. LNG ATB gets ABS Approval in Principle
Classification society ABS has granted approval in Principle (AIP) to a new liquefied natural gas (LNG) and regasification articulated
tug barge concept introduced by Waller Marine Inc, Houston.

The vessel has the ability to load LNG from existing LNG terminals, liquefaction facilities or traditional LNG carriers and transport
the LNG to existing tanks, traditional LNG carriers, trucks or marine vessels using LNG as a fuel. The barge also is equipped for
regasification of LNG directly to a pipeline or to a power plant. An additional feature will be the use of natural gas as a fuel in the
dual fuel engines of the tug to drive the tug-barge unit.

The benefit of the LNG Articulated Tug and Barge Regas Vessel (ATB RV) is that it allows LNG to be moved and delivered more
efficiently on a small-scale basis in locations where large LNG infrastructure would be cumbersome, costly and time consuming.

The barge will be fitted with independent Type "C" LNG tanks. To make most efficient use of the hull volume and maximize the
cargo-carrying capacity of the barge, bi-lobe tanks of maximum width are centered along the barge centerline. The cargo
containment system is split into four longitudinally located independent tanks, with each tank supported by a simple structure that
isolates the tanks from hull loads. According to Waller Marine, these tanks will be constructed of either 9 percent nickel steel or
Stainless Steel AISI 304L to contain the cargo at a minimum temperature of -163 degrees C.

ABS worked with Waller from the inception of the project and has been the primary certification body in carrying out reviews,
including conducting a program review.

"ABS has been a great resource in developing the LNG ATB RV product", says Vice President-Gas Solutions Bill Hutchins, Waller
Marine. "By conducting multiple meetings-including a HAZID (hazard identification)-ABS has helped us to ensure safety and
regulatory aspects have been appropriately addressed."

"ABS has worked closely with Waller Marine through the development of the LNG ATB RV," says Roy Bleberg,
Director-Engineering, ABS Americas. "We are pleased to be part of a project with the potential to improve the environmental impact
of hydrocarbon emissions."

Since AIP was granted, Waller Marine has moved into the detail design phase with a goal of creating multiple variations for clients
around the world.
Waller Marine Inc. uses AVEVA PDMS to Design Venezuelan Power Barges
Mark McKee, Marketing Specialist, AVEVA Americas
AVEVA World Magazine, 2011, Issue 2

Houston's Waller Marine, Inc. (WMI) faced a tough challenge:  Design, build and deliver two 171 MW floating power barges to a
customer in Venezuela... in just 180 days.

Such a project required not only focus, speed and know-how, but a tool that would enable WMI to maximize its 36 years of naval
architectural expertise on a very tight deadline with no margin for error. The firm turned to AVEVA in early 2010, purchased four
PDMS licenses and rolled up its collective sleeves with little time to spare.
From idea to reality
The result? The Margarita I and the Josefa Rufina I floating power plants set sail for Venezuela on schedule in August 2010 from
Ingleside, TX. Only six short months earlier, both were mere ideas. How did WMI complete the fast-track project in such a tight

"The project schedule would have been impossible to achieve without tireless dedication and a shared vision of success by all involved."
said Stephen J. McKillop, WMI's Vice President of Engineering.

"We chose to team our in-house engineering staff to work hand-in-hand with a highly motivated and talented shipyard whereby the
barge hull, equipment foundations and piping systems were being engineered, constructed and installed almost simultaneously,"
McKillop explained, adding it was a strategy which could have been a recipe for mistakes, reworks and delays, were it not for the real
time communication and strict scheduling of the various activities.

McKillop said the final piece of the construction puzzle was to install the power plant and electrical switchyard. "(It) was completed by
highly qualified turbine and electrical technicians specifically contracted by WMI for their dedication and 'can do' attitude," he said.
"PDMS was a vital tool in allowing accurate installation and fit-up in our balance of plant-to-turbine piping interfaces."
of a football field and each weighs 6,700 short tons apiece. Their
stack towers soar 100 feet above the decks. Boasting identical GE
7FA simple-cycle, dual-fuel turbine generators, the barges can each
generate 171.4 MW of electricity for transfer to the Venezuelan
grid. The turbines can run on natural gas or number 2 fuel oil.

The barges will be moored in a shallow, man-made basin protected
from the Caribbean Sea, near the Planta Termoelectrica de Taco -
an overtaxed 1940s-era power plant on the coast northwest of
Caracas that cannot operate at anywhere near 100 percent capacity
due to age.

Venezuela's nearby hydroelectric plants have been unable to take up
the slack with additional power due to a shortage of rainfall in the
region, which has led to lower than normal reservoir levels needed
to power the hydro turbines. As a result, Caracas and the
surrounding areas have been experiencing frequent power

A year ago, the Guri Hydroelectric power station, which provides almost 70% of Venezuela's electricity, fell to critically low levels, due to
a prolonged drought, excess demand on the dam in 2009 and the absence of thermal generation....
May 5 - Two Power Barges installed to increase generation
capacity by 342 MW
Operations of power barges, Margarita and Rufina, are expected
to begin in July. The two floating power plants will increase the
generation capacity by 342 megawatts (MW). The plants located
near Caracas are used to meet power demand in the Venezuelan

The barges have already been installed near the Picure and Tacoa
power plants. Each has a generating capacity of 171 MW, fo a
total of 342 MW.

Minister of Electricity, Ali Rodriquez, visited the Picure power
plant and opened Units 1 and 2 which have a generating capacity
of 44 MW each. The other two units are expected to be installed
in a month.

Waller Marine to Develop New LNG Terminal Facility
Houston, TX - November 12, 2012
Holdings, LLC and Waller LNG Services, LLC (the Company), has initiated
activities on its first natural gas liquefaction (LNG) facility to be constructed
on a 175 acre site the Company has acquired at the entrance point of the
Calcasieu Ship Channel in Cameron Parish in Southwest Louisiana. Using
small-scale Liquefaction technology, the Company plans to install nominal
500,000 gallon per day LNG trains in phases as the market and demand for
marine LNG fuels inevitably expands. The first trains are planned for the
Waller Point LNG terminal in Cameron Parish, and additional trains are
planned for a second terminal which it is developing through its subsidiary
Waller Energy Partners, LLC, at a site to be secured on the Mississippi River
in the first quarter of 2013. These will be the first two of the initial seven
small scale LNG terminals the Company plans to install at strategic locations
on each US coast.
With the looming regulatory requirement for vessel's to comply with new ECA emission control regulations when operating in the
territorial waters of the United States, the Company's focus is to supply LNG to the marine fuels market. To enable the supply  and
distribution of LNG to and from small scale LNG terminals and for bunkering LNG as a marine fuel, Waller has been the first to
conceive and design a series of small LNG vessels ranging from its 2,000 to 10,000 cubic meter capacity river transport and bunker
barges and its 10,000 to 30,000 cubic meter coastwise ATB LNG vessels. Waller's innovative concepts are patent pending before the
USPTO, and Waller has recently acquired Approval in Principal from the American Bureau of Shipping (ABS).
Marine firm will build small LNG plant in Louisiana to serve ships
Latest Oil and Gas News:  March 4, 2013
(The Advocate; Baton Rouge, LA; March 1) - Houston-based Waller Marine will build a small-scale LNG facility at the Port of Greater
small compared with the billion-dollar export projects announced in Louisiana in recent years. Waller plans to spend $200 million initially,
though that amount could double as it adds capacity, company officials told the port commission Feb. 28.

The facility will employ 45 people initially and could double that when fully built out, said Taylor Norton, Waller's chief general counsel.
Waller, a naval architecture and marine engineering firm, will work with existing port tenant Kanorado Corp. to turn Kanorado's 11-acre
facility into a 25-acre joint effort, with both realizing it would be mutually beneficial if they teamed up at the site. Kanorado's terminal
moves sand, rocks and other aggregate.

David Waller, who founded Waller Marine, told commissioners that beginning in 2015 ships will have to use cleaner-burning, low-sulfur
diesel fuel to comply with emissions standards. He said the fuel isn't as economical as making ships capable of running on super-cooled
liquefied natural gas. Norton said Waller Marine wants to have the LNG facility operational within the next year and a half.
