The Jacksonville LNG project is a one million tonne per annum (Mtpa) liquefied natural gas (LNG) export facility planned to be developed in Jacksonville, Florida, US.
The project is being developed by Eagle LNG, a wholly-owned subsidiary of Ferus Natural Gas Fuels. It is estimated to require an investment of approximately $500m.
Jacksonville LNG facility will be capable of processing 1.5 million gallons of LNG a day and store up to 12 million gallons of LNG.
The final environmental impact statement (FEIS) from the United States Federal Energy Regulatory Commission (FERC) for the project was issued in April 2019. Construction of the project is scheduled to be commenced in the second half of 2019, while commissioning is planned for 2021.
Jacksonville LNG project location
The Jacksonville LNG project will cover approximately 70.7 acres of land and 11.1 acres of submerged lands on the north bank of the St. Johns River in Jacksonville, Duval County, Florida.
Jacksonville LNG terminal details
The LNG terminal will include three LNG trains, each with a capacity to produce 550,000 gallons of LNG a day (0.33Mtpa). Each train will be equipped with an acid gas removal unit (AGRU), dehydration and mercaptans removal unit, mercury removal unit, and a gas liquefaction unit.
The terminal will have one full-containment, double-walled LNG storage tank with a capacity to store 45,000m³ of LNG produced by the trains. The LNG will be pumped from the storage tank to the marine transfer facilities, where it will be loaded onto LNG carriers using cryogenic piping.
The terminal will be equipped with marine facilities including an access trestle and loading platform. It will also feature two loading arms capable of handling LNG vessels with capacities of up to 45,000m³. Between 40 to 100 LNG marine vessels are anticipated to be loaded at the LNG terminal a year.
The terminal will also feature dual bay LNG truck loading facilities capable of loading between 260 and 520 LNG trucks a year.
Infrastructure and construction details
The marine facilities of the terminal will be dredged using hydraulic cutterhead suction and mechanical dredging techniques. An estimated 179,000 cubic yards of dredged material is expected to be removed for the facilities.
Electricity supply for the Jacksonville LNG project will be sourced from a 138kV transmission line operated by the Jacksonville Electric Authority (JEA). Two new 200ft-long, 138kV transmission lines will be constructed to connect the JEA transmission line to the switchgear located within the site.
The supporting infrastructure of the terminal will include a boil-off gas (BOG) compression system, on-site refrigerant storage, ground flare, and a cold vent system. Other facilities for the project include administration, control, and workshop buildings.
Feed gas supply
Natural gas will be provided by People Gas through its existing 24in diameter gas transmission pipeline situated next to the project site boundary.
A new 120ft-long and 16in diameter interconnect pipeline will be constructed to link the project facilities with the existing gas pipeline.
Amec Foster Wheeler conducted the geotechnical exploration for the Eagle LNG processing terminal, while Siebein Associates and Trinity Consultants prepared the noise impact analysis report of the project.
Fugro was awarded the contract to conduct the geotechnical investigations for the EIS of the project.
Other contractors involved in the project are Cardno ENTRIX, a US-based environmental and social development company, and Genesis | Halff, a US-based civil engineering company.
