CGL transportation solutions

Transportation of CGL is via purpose-built vessels of varying capacities to suit the demands of the customers and facility constraints at the export and receiving terminals. Designs have been developed for an Articulated Tug/Barge (AT/B) unit with a capacity of 440 MMSCF, and for Compressed Gas Liquid Carriers (CGLCs) with capacities of 1.0, 1.5, and 2.0 BSCF.

The American Bureau of Shipping (ABS) has worked closely with SeaOne for more than a decade in the development of the CGL containment system that will be used in the vessels. The same containment system will be used to store CGL in the export and receiving terminals.

All vessels engaged in the transportation of CGL will be classed by the American Bureau of Shipping, and will be built to meet or exceed the safety and environmental standards of ABS, flag and port states, and the International Maritime Organization (IMO). The ships will meet all applicable requirements of the International Gas Carrier (IGC) Code.

The hullforms for the CGLCs have been extensively refined using Computational Fluid Dynamics (CFD), confirmed by model tests, to minimize resistance.

Low emissions from CGLC propulsion and power generating systems is guaranteed by using propane for fuel. The systems will feature state-of-the art hybrid power components, including renewable energy storage to achieve further reductions in fuel consumption, emissions, and maintenance costs.
