The Elba liquefaction project primarily involves the addition of liquefaction facilities to Southern LNG Company’s (SLNG) existing Elba Island LNG Terminal, located at Elba Island in the Savannah River, Chatham County, Georgia, US.
The project received approval from the US Federal Energy Regulatory Commission (FERC) in June 2016.
The proposed project is being jointly implemented with the EEC Modification Project, which involves the installation of two compression stations along Elba Express Company’s (EEC) existing 200km Elba Express Pipeline to supply natural gas to the terminal.
Elba Liquefaction Company (ELC), a joint venture of SLNG and Shell US Gas & Power is implementing the project.
SLNG is a unit of Kinder Morgan and El Paso Pipeline Partners (EPB), while Shell US Gas & Power is a subsidiary of Royal Dutch Shell. Elba Express Pipeline owner EEC is also a unit of Kinder Morgan.
The total investment for the project is estimated to reach approximately $2bn.
The terminal received the US Department of Energy’s (DOE) approval to export up to four million tonnes per annum (Mtpa) or 500 million cubic feet a day (Mmcfd) of LNG to Free Trade Agreement (FTA) countries.
Meanwhile, the DOE’s approval to export up to 4Mtpa (500Mmcfd) of LNG to non-FTA countries was granted in December 2016.
Elba liquefaction and EEC modification project details
The Cameron Liquefaction Project involves the construction and addition of natural gas liquefaction and export facilities to the existing LNG regasification facility at Cameron LNG.
The liquefaction capacity earmarked for the project is approximately 2.5Mtpa or 350Mmcfd of LNG.
The project is being carried out in two phases. Phase one will involve the installation of six liquefaction units with a combined output capacity of 210Mmcfd and the implementation of the EEC modification project, while phase two will add two to four additional liquefaction units with a combined output capacity of 140Mmcfd.
Installation of a flare system while also take place through the project, as will modifications to the terminal piping, modification and construction of a number of buildings, truck transport of natural gas liquids, and modifications to electrical distribution facilities.
The EEC modification project will also be carried out in two phases. Phase one involves the installation of a new 16,000hp compressor at Hartwell Compressor Station in Hart County, Georgia, while phase two will involve the installation of a 11,000hp compressor station, and 1,000ft of interconnecting pipeline in Jefferson County, Georgia. The preliminary engineering design for the project was completed in January 2014.
Phase one construction of the liquefaction project began in November 2016 and initial liquefaction units are expected to come online in mid-2018, while phase two is expected to come online in early 2019.
Treated gas from the liquefaction units will be stored in the existing storage tanks and then loaded onto LNG vessels berthed at the existing marine facility for export.
Liquefaction technology for the Elba project
The project will implement Shell’s small-scale movable modular liquefaction system (MMLS). Each MMLS features two parallel refrigeration trains for reliability. The technology also allows for fabrication of equipment from manufacturing sites and easy installation at the project site.
Key players involved
The front-end engineering design (FEED) study for the project is being performed by CB&I. CH-IV International assisted CB&I to file the resource reports.
The biological field surveys for the project, including a wetland delineation report, were performed by CH2M Hill Engineers, while cultural resource field surveys were conducted by R Christopher Goodwin & Associates.
In April 2016, IHI E&C received a contract for the engineering, procurement and construction (EPC) of the liquefaction project.
In June 2016, HDR was preferred as the owner’s engineer for the Elba LNG export project.
