CGL™ transportation solutions
Ocean-going Compressed Gas Liquid™ Carriers (CGLCs) and Articulated Tug Barges (AT/Bs) are designed to transport the CGL cargo. SeaOne has designed, engineered, and third-party verified these vessels.
0.44 BCF AT/B 853 feet long and 127 feet wide with a draft of approximately 26 feet. Able to dock at shallower draft ports.
1.0 BCF CGLC 1,000 feet long and 150 feet wide with a draft of approximately 36 feet. Able to dock at shallower draft ports.
2.0 BCF CGLC 1,200 feet long and 160.75 feet wide with a draft of approximtately 50 feet in fresh water. Able to traverse the Panama Canal locks.
CGL Storage System The cargo hold is refrigerated to minus 40ºF and is nitrogen purged. The CGL storage system is 100% filled with the CGL cargo. Due to the mild operating temperature and pressure, the CGL storage system can be constructed using primarily low-temp 42" carbon steel pipe. The same type of containment system in the CGLCs will be used to store CGL in the export and receiving terminals.
CGLC Facts
- 100% full cargo containment means no sloshing, no free surface area, no boil-off issues, and no heel
- FEED studies completed on several CGLC sizes
- Vessel technical reviews completed and approved by the American Bureau of Shipping (Class), Marshall Islands (Flag State), United States Coast Guard, and the International Maritime Organization
- 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 CGL storage system has also received Approval in Principle status from Lloyd’s Register
- The ships will meet all applicable requirements of the International Gas Carrier (IGC) Code
- The hullform of the 2.0 BCF CGLC has been subjected to Computational Fluid Dynamics (CFD) testing and confirmed by model tests
- Low emissions guaranteed from CGLC propulsion and power generating systems by using propane for fuel. The systems will also feature state-of-the art hybrid power components, including renewable energy storage to achieve further reductions in fuel consumption, emissions, and maintenance costs
- Designs have also been reviewed by the Mississippi State Pilots of Gulfport, MS and the Aransas-Corpus Christi Pilots
- SeaOne expects to enter into a CGLC Unit Time Charterparty Agreement for each CGLC
