Over the past 10 years, the world has witnessed a steady increase in the demand for natural gas. It has now become the fuel of choice. All energy analysts predict global demand to double in 15 to 20 years. In North America and areas of Southeast Asia, the value of natural gas has more than doubled due to a steady decline of supply. With half of the world's reserves considered stranded, an alternative method to economically transport gas by ship will be highly valued. Compressed Natural Gas (CNG) transportation is viewed by many industry and industry-related companies as that viable transportation option. Within this emerging industry, many consider the Trans Ocean Gas method as the optimal solution for CNG transportation.

CNG can economically transport stranded gas reserves to existing markets or create new natural gas markets not applicable to LNG. In contrast to LNG, compressed gas requires no processing to offload. So it can economically deliver natural gas fuel for electrical power generation startups. There are hundreds of places in the world where CNG would be ideal for new market creation.

Trans Ocean Gas Inc. (TOG) proposes the most unique method of CNG transportation using composite pressure vessels. The fiber reinforced plastic (FRP) pressure vessel gas containment system overcomes all the deficiencies of proposed steel-based systems. FRP pressure vessels have been proven safe and reliable through critical applications in the national defense, aerospace, and natural gas vehicle (NGV) industries. They are light-weight, highly reliable, have very safe failure modes, are corrosion resistant, and have excellent lowtemperature characteristics. The TOG method utilizes FRP technology, modified in size to store a large quantity of gas on a ship.

TOG has already obtained an approval in principle for the gas containment system from the American Bureau of Shipping. With its strategic partners, General Dynamics ATP and BMT Fleet Technology, TOG will now perform detailed design of a complete CNG carrier for approval in principle of the entire ship. It will then perform design verification testing on prototype pressure vessels. With a successful testing program, Trans Ocean Gas will be ready to commercialize its technology.

Fiber Reinforced Plastic pressure vessels are safe, very reliable, light-weight, corrosion resistant, and have excellent low-temperature characteristics. They are therefore the optimal solution for CNG transportation.

FRP pressure vessels are manufactured using the plastic liner as a mandrel on a computer controlled winding machine. As the mandrel is spun, a continuous filament of carbon, aramid, or glass fiber is drawn through an epoxy bath then wound onto the liner in a helical formation. It is the filament windings that provide the strength in an FRP pressure vessel When cured, the filament windings are held in place by the epoxy matrix.

The main criteria in the NGV industry are ultra light weight and safety. Therefore, carbon fiber is the filament fiber primarily used to manufacture pressure vessels for that industry. Carbon fiber has a very high strength to weight ratio. It is about 12.7 times stronger than high-strength steel.
