The AES Ocean LNG terminal will be located on the south side of Ocean Cay, The Bahamas.
The facility will comprise a liquefied natural gas (LNG) removal plant and storage facilities, a desalination plant, an undersea natural gas supply pipeline, liquefied petroleum gas (LPG) terminal, LPG storage, an LPG removal plant, ragasification, sendout system and ancillary structures, and an ancillary electricity generation unit.
A berthing facility will receive LNG from tanker ships and then store it in two 160,000-m3 LNG tanks. There will be secondary containment berths constructed on the southwest of Ocean Cay for future terminal expansions.
The LPG terminal will consist of a berthing facility and a storage unit with a 40,000-m3 tank located within a secondary containment berm. The tank will receive LPG from the LPG removal operation for storage before it is shipped from the island.
The LPG removal plant will receive LNG and remove propane, butane and other gases. It will then pipe these products to the LPG tank for storage. Following the removal of the LPG, the LNG will then be sent to the regasification and sendout system.
The regasification, sendout system and ancillary structures include an auxiliary equipment building, an administration building, a warehouse, and a compressor building. The ancillary electricity generation houses three 15-MW natural gas-fired turbine generators and will generate electric power for the project facilities load.
A desalination plant will also be constructed for potable water and process the terminal’s water supply. The unit will be a two-stage reverse osmosis unit with a 50,000 GPD capacity.
The final component of the facility will be a 26-inch undersea natural gas pipeline, Ocean Cay Pipeline, which will extend from Ocean Cay to the Exclusive Economic Zone boundary between The Bahamas and the United States. The pipeline will interconnect with a new 26-inch undersea natural gas pipeline extending to delivery points in Florida. The newly constructed pipeline will transport 22.7 million cubic meters of gas per day.
The LNG terminal will come onstream in 2012 and is expected to send approximately 842 million cubic feet a day of gas to Florida.
