The technical clout and competitive influence exerted by the creation of the partnership venture

Compressed Energy Technology (CETech) has enhanced prospects for the realization of a new breed of gas car- rier, designed and engineered specifical- ly for the envisioned trade in CNG.

Newly-established CETech's brief is the commercialization of new systems for the transport of CNG, and its aim is to be a leading player in the development and licensing of compressed gas shipping technology. Shipment in compressed rather than liquefied form offers poten- tial cost and operational benefits in spe- cific applications.

The main potential for the concept is seen within a transport range of

It opens the way to exploitation of resources where field size and location means that transportation is not com- mercially viable if based on LNG or conventional pipeline solutions. "Associated gas from oil fields can now be commercially exploited instead of being flared off on the field or injected back into the reservoir," observed

CETech. The main potential for the con- cept is seen within a transport range of 300-2,000 nautical miles, and where production volumes are in the order of 0.5 to 3-billion cubic meters per year.

CETech is the result of more than two years' collaboration with the research department of Norwegian classifica- tion society Det Norske Veritas, which has also played an active part in verifi- cation and quality assurance of the tech- nology. The company's CNG concept has secured approval in principle from

DNV, and patents have been applied for on a number of technological systems.

The proposed CNG vessel series would offer a cargo tank volume of 30,000- 100,000 cubic meters, requiring contain- ment at pressures of some 200-250 bar.

Various interests worldwide are pro- moting CNG projects, which could result in orders being placed for dedicat- ed newbuilds. One contender for future contracts is Hyundai Heavy Industries of South Korea, which has been working with EnerSea Transport since 2002 on the development of vessel designs based on the Houston company's Votrans tech- nology.
