| Specialized Vessels |
The Company has produced special purpose vessel designs for various
industries, including floating offshore terminal for product and crude oil
loading, floating facilities for Ocean Thermal Energy Conversion (OTEC),
floating facilities supporting bauxite plants and compressed natural gas
ships for ocean transportation.
| Cable Lay Barge |
Waller Marine contracted to design and construct a dynamically positioned Multi-Purpose Cable Lay Barge. This EPC contract requires
Waller Marine to provide the turnkey supply of the barge and all specialized cable storage and lay equipment delivered to Nigeria. The
vessel will be designed to lay electric cable, fiber optic cable and umbilicals in the rivers and coastal estuaries of Nigeria and in
offshore waters up to 300 meters water depth.
The ocean going barge is designed specifically for cable lay service. With dimensions of 275 ft x 75 ft x 16 ft, the vessel will be classed by Lloyd's Register, meet all IMO requirements and be flagged in the Republic of Panama.

A deck mounted 100-tone crane and a 40-ton dynamic "A" frame fitted with a cable lay and burying sled for up to eight feet depth below the sea bed round
out the barges cable lay capability.
Accommodations are provided for 37 crew and company personnel in single and double cabins complete with recreation, exercise rooms, laboratories, hospital and modern galley and mess. The facilities are fitted with a helicopter deck and capability of resupply from water borne supply vessels.

The barge will be constructed to Lloyd's Class DP AA dynamic positioning capability, using six diesel-hydraulic thruster units manufactured
by Thrustmaster of Texas, with controls installed by Kongsberg DP Systems. Positioning and station keeping is augmented by a four part
mooring system.

| World's First Floating Methanol Plant Could Play Role in Alleviating U.S. Energy Shortage |
HOUSTON, July 29, 2003/PRNewswire/
PetroWorld, along with three international partners, on July 16 announced that they are developing the world's first floating large-scale, fuel-grade methanol plant designed to extract natural gas from reserves in remote areas and convert it on board into liquid methanol at a rate of 12,000-15,000 tons of output per day. A primary market for the product is certain gas turbine power plants in the U.S., where methanol would be an advantageous alternative fuel. The $700 million plant will be deployed off Africa's west coast about three years from the date that project details and financing are finalized.
The partnership hopes to develop and deploy additional plants in appropriate maritime locations around the world that have "stranded gas". *Unlike oil, liquid methanol can be produced and sold at a less volatile price, which is good news for U.S. power companies currently at the mercy of fluctuating oil and gas prices.

The partnership hopes to develop and deploy additional plants in appropriate maritime locations around the world that have "stranded gas". *Unlike oil, liquid methanol can be produced and sold at a less volatile price, which is good news for U.S. power companies currently at the mercy of fluctuating oil and gas prices.
The world's proven natural gas reserves are in excess of 5,000 trillion cubic feet, which is enough to satisfy one-third of total world oil
demand for 35 years. However, half of these gas reserves are "stranded", meaning they are located off the shores of countries where is
uneconomical to build liquid natural gas(LNG) facilities on shore, not to mention the cost of transportation in specially refrigerated tankers
(since no pipeline system exists). The floating methanol plant is ideal... it eliminates any on-shore investments and liquid methanol can be
transported in ordinary tankers. The principal challenge was developing a cost efficient methanol plant that would fit on a vessel, which
was accomplished by Starchem Technologies, Foster Wheeler Power Systems and Waller Marine.
About the Partners
The world's first floating methanol plant is being jointly developed by PetroWorld Limited (a 50-50 joint venture between PetroSA, the Petroleum Oil and Gas Corporation of South Africa Ltd., and Transworld Exploration Ltd., part of the Transworld Group of Companies), Perryville, New Jersey-based Foster Wheeler Power Systems Inc., Houston-based Starchem Technologies International Ltd. and Houston-based Waller Marine, Inc.

Offshore Gas to Liquids Facility - Methanol
The integration of a new methanol process technology with a marine
vessel permits the conversion of large quantities of remote or stranded
gas to a liquid for transport to markets for use as fuel for power
generation or feedstock for the petrochemical industry in the conversion
of methanol to olefins (MTO).
The methanol plantship comprises a double hull structure of 1,000 ft in
length by 200 ft beam, with storage capacity of 250,000 tons of methanol
product. The process plant is supported on the process deck, similarly to
a traditional FPSO. Moored by an extended turret, gas is supplied through
a riser and swivel at rates up to 400 mmscf/d.

The barge is designed with high motion suppression features, constant draft and has the ability to change it's vertical center of gravity by
moving ballast in order to modify it's natural frequency for motion reduction. Designed for worldwide operations, the facility can accept
wellhead and dry gas, producing either fuel or AA grade methanol for shipment. Product is stored in sufficient quantities to load out 200,000
dwt tankers for transport to either the power generation or MTO chemical markets.
