The Gulf Coast LNG Export Terminal Expansion is a high-complexity megaproject designed to support rapidly increasing global demand for liquefied natural gas. Once complete, the expansion will increase export capacity by 40%, strengthen U.S. energy independence, and improve international trade reliability.
Civil & Earthworks
- 1.7 million cubic yards excavated
- Ground improvement using deep-soil mixing
- Flood-resilient platform construction
- Coastal erosion control infrastructure
LNG Storage & Cryogenic Engineering
The heart of the expansion is the construction of two 220,000 m³ cryogenic storage tanks.
Key Features
- 9% nickel steel inner tanks
- Reinforced concrete outer shells
- Advanced thermal insulation
- Automated leak-detection systems
Marine Loading Facilities
To accommodate increased export traffic:
- Two new loading berths
- Reinforced mooring dolphins
- High-capacity loading arms
- Digital ship-tracking systems
Marine crews coordinate closely with port authorities to ensure environmental compliance.
Pipeline & Mechanical Systems
The expansion includes:
- 14 miles of cryogenic-grade pipeline
- Compression stations
- Gas treatment facilities
- Control rooms with real-time monitoring
Safety & Environmental Commitment
- Active air-quality sensors
- Spill-prevention berms
- Wetland restoration zones
- Hurricane-rated structures
The project maintains zero environmental violations.
Workforce & Equipment
- Peak workforce: 1,150 personnel
- Safety rating: 99% compliance
- Equipment fleet: Cranes, pipe layers, excavators, marine barges
This LNG expansion is poised to become one of the most important energy-export infrastructure upgrades in North America.
