Project Report
Port Arthur LNG project underway
Port Arthur LNG Phase 1, already under construction, will help meet global demand for LNG. The liquefaction project will provide a reliable supply of LNG to energy markets around the world.

The Port Arthur LNG Phase 1 project is fully permitted and designed to include two natural gas liquefaction trains, two LNG storage tanks and associated facilities with a nameplate capacity of approximately 13 million tonnes per annum( Mtpa), nameplate capacity. Total capital expenditures for the Port Arthur Phase 1 project are estimated at USD13 billion. The long-term contractable capacity of approximately 13 million tonnes per annum( Mtpa) is fully subscribed under binding longterm agreements with strong counterparties— ConocoPhillips, RWE Supply and Trading, PKN ORLEN S. A., INEOS and ENGIE S. A., all of which became effective upon reaching final investment decision( FID). Additionally, a 3.5-mile portion of Highway 87 between the Intracoastal Waterway and Keith Lake Pass, which extends to the community of Sabine Pass, was relocated to accommodate the project and built to Texas Department of Transportation standards. Bechtel has been selected to be the engineering, procurement, construction and commissioning( EPC) contractor. Construction commenced on Phase 1 of Port Arthur LNG at the end of March 2023.
Phase 1 is designed to include:
• Two natural gas liquefaction trains capable of producing, under nameplate capacity, up to approximately 13 Mtpa
• Two LNG storage tanks
• Marine facilities, including a marine berth for LNG vessel berthing and loading of LNG
• Natural gas liquids and refrigerant storage
• Feed gas pre-treatment
• Truck loading and unloading areas
Strategic location
• The project is located along the Sabine- Neches ship channel, a strategic location near abundant natural gas resources with direct access to the Gulf of Mexico.
• Access to robust, North American interstate gas pipeline system
• Large contiguous site with large laydown areas
• Channel is maintained for deep draft vessels( Q-Max)
Part of this project will be supplied by AMPO POYAM VALVES with more than 15,000 LNG valves during 2023, 2024 and 2025, including highly engineered cryogenic and non-cryogenic ball valves as well as cryogenic and non-cryogenic gate, globe and check valves.
Cryogenic and non-cryogenic ball valves in LNG
Cryogenic ball valves are specially designed to handle extremely low temperatures, especially those found in LNG processes. As the name suggests, these valves are built to withstand the challenges of cryogenic fluids, such as LNG, which can be as cold as-162 degrees Celsius. The materials used in cryogenic ball valves are often chosen for their strength and reliability at these low temperatures. Additionally, cryogenic valves feature unique design elements such as extended stem lengths and specialised sealing systems to ensure leak-tight performance and prevent valve failure in harsh conditions.
