World’s first CNG ship approved for construction

Sea NG Corporation (www.coselle.com) announced that the American Bureau of Shipping ("ABS") has approved for construction its Coselle compressed natural gas ("CNG") ship. This is the first ship and cargo system in the world for the transport of CNG to be so approved by ABS or any other international marine classification society.

Coselle CNG ships will be deployed to carry moderate volumes of natural gas (30 to 500 mmscf) over medium distances (200 to 2,000 km), a segment of the marine gas transportation market that has not been economically served by pipelines or liquefied natural gas.

The Coselle is a unique, patented system, invented in Canada, for storing high-pressure gas in a coil of small diameter pipe.  Numerous Coselles are contained within the specially-designed ship.  This storage system hassignificant safety and cost advantages over conventional large diameter pressure cylinders.  The Coselle CNG System has been in development for a decade by a team of experienced gas and marine engineers.

Typically, ten miles of small diameter, high-strength X70 pipe is coiled into a reel-like structure, called a carousel. This carousel provides support and protection for the transportation and stacking of Coselles. The name “Coselle” originates from a contraction of the words “coil” and “carousel” and is a unique industry term developed a decade ago.

The size of a Coselle may range from 15 to 20 metres in diameter and 2.5 to 4.5 metres in height, and it may weigh about 550 tonnes. A single Coselle carries about 3.0 million standard cubic feet (mmscf) of natural gas, depending on Coselle dimensions, and gas temperature, pressure and composition.

A major advantage of the Coselle CNG System is that it requires minimal on-shore facilities.  Gas can be loaded and discharged at simple port-side pipeline facilities, which greatly reduces environmental, land-use and financial concerns.  Gas can also be trans-shipped at offshore buoys if a port is not accessible.

Is there such a ship in operation commercially? Where and what is the track record?

Years of working on the Coselle CNG ship has finally paid off. Congratulations to the team of experts who really did a great job on the specially-designed ship. With the present number of companies in the marine and offshore industrial supplies field, more specialized ships are sure to be constructed. This is definitely good news!

Off-shore accommodations need to have that guarantee that they can withstand extreme weather conditions since workers or residents stay there for months, even years. Spending time at sea can be dangerous at times and so your vessel should be made with quality. Various kinds of potential danger is imminent especially if your ship is carrying oil or natural gas and ensuring that none of these will occur should be prioritized.
