October 01, 2018 [Hydrocarbons Technology] - The Calcasieu Pass liquefied natural gas export facility in Cameron Parish, Louisiana, US, is being developed by Venture Global Calcasieu Pass, a subsidiary of Venture Global LNG.
The project also includes the construction of a 42in-diameter, 23.4-mile (37.66km) pipeline named TransCameron, which will connect the facility to interconnection points around Grand Cheniere Station.
The export facility will store approximately 516 billion cubic feet (bcf) of natural gas a year, which is equivalent to ten million tonnes per annum (Mtpa). The peak capacity is estimated to be 620bcf a year (equivalent to 12Mtpa).
FERC issued its Notice of Availability of the draft environmental impact statement for the proposed facility and TransCameron pipeline in June 2018. Final investment decision on the project is expected to be made in early-2019, with operations are scheduled to commence in 2022.
The project is estimated to create approximately 1,500 construction jobs and 130 operational jobs.
Calcasieu Pass LNG Export Facility Details
The Calcasieu Pass LNG export facility is being developed to the south of Lake Charles on the Calcasieu Ship Channel near the Gulf of Mexico. The location lies in close proximity to abundant gas supplies and transport facilities. The facility will extend over 930 acres and have deepwater access.
The export terminal will incorporate modular LNG liquefaction technology comprising two trains of natural gas liquefaction. The liquefaction system will include 18 mid-scale modular trains driven by electric motors to achieve optimum efficiency and reliability.
The LNG facility will comprise nine pre-cooled single mixed refrigerant blocks, each with a nameplate liquefaction capacity of 1.2Mtpa. The blocks will include refrigerant storage vessels and distribution piping between the refrigerant storage site and liquefaction blocks.
Infrastructure Facilities at the Terminal
LNG is proposed to be stored in two 200,000m³ full-containment LNG storage tanks. The LNG will be loaded onto carriers docking at one of two LNG berthing docks in a common recessed berthing area. The marine terminal will accommodate carriers up to 185,000m³ in capacity.
Calcasieu Pass will also feature a 720MW natural gas-fired combined-cycle gas turbine electric generation facility.
TransCameron Pipeline Details
The TransCameron pipeline system will be located entirely within Cameron Parish, Louisiana, and will comprise a meter station and three main line valves (MLVs).
A pig launcher will be constructed at the meter station, while one pig receiver will be constructed at the gas gate station on the terminal site.
LNG Offtake from Calcasieu Pass
Venture Global LNG entered an agreement with Polish Oil & Gas Company (PGNiG) for the purchase of 2Mtpa of LNG for a period of 20 years, in June 2018. The cargo will be delivered to the Plaquemines LNG facility, starting from 2023.
Venture Global Calcasieu Pass has entered an agreement with BP (BP LN) for the sale of 2Mtpa of LNG on a free on-board (FOB) basis. The sale is made under a sales and purchase agreement (SPA), which is valid for 20 years.
The company has also entered separate 20-year SPAs with Galp, Shell NA LNG (Shell), and Repsol for the supply of 1Mtpa of LNG from the facility.
Contractors involved with Calcasieu Pass LNG export facility
CB&I was awarded the $200m engineering, procurement and construction contract for two LNG storage tanks at Calcasieu Pass.
GE Oil & Gas is the supplier of LNG process system for the export facility.
Providence Engineering and Duplantis Design Group are responsible for the permitting and design of 130 acres of marsh required for the terminal and pipeline system.
