Baker Hughes will supply gas compression and power generation equipment, along with project development support, for ST LNG LLC’s proposed 8.4-MTPA liquefied natural gas (LNG) export terminal. The offshore facility will be located 10.4 nautical miles (19.2 km) off the coast of Matagorda, Texas.
For the first phase of development, Baker Hughes will deliver two LM6000PF gas turbine-driven centrifugal compressor trains and three NovaLT16 gas turbine generator packages. This equipment will provide the production capacity needed to support Phase 1 output of 2.1 MTPA, part of a planned four‑phase development strategy. Each phase will consist of identical components and equipment configurations.
Each development phase will include three primary fixed platforms housing LNG production infrastructure: a liquefaction platform containing all liquefaction equipment; a gas treatment platform hosting gas treatment systems and thermal oxidizers; and an accommodation and utilities platform providing living quarters and essential utility systems.
The project scope also includes construction of a 3.1-mile (5‑km) lateral pipeline connecting the facility to an existing offshore pipeline network. Under the base‑case design scenario, the terminal is expected to require approximately 1.2 bcf/d (35.6 x 106 m3/d) of natural gas feedstock to produce and export the full 8.4 MTPA of LNG.
In total, the project would involve construction of approximately 16 offshore platforms across four phases. Each phase will be capable of treating roughly 330 MMscf/d (9.5 x 106 m3/d) of pipeline‑quality natural gas to LNG specifications.
Natural gas supply for the facility is planned through a short lateral pipeline connecting the project’s supply header to Transco’s offshore pipeline system, approximately 10 miles (16 km) offshore near Brazos Block 450. At this location, Transco operates parallel 36‑inch (91-cm) and 30‑inch (76 cm) pipelines that were originally designed to move offshore gas onshore. These pipelines can be flow‑reversed to transport gas from onshore supply sources to the offshore LNG facility and are currently operating at approximately 50% utilization.
ST LNG LLC intends to interconnect with one of these offshore headers to receive feed gas via the Transco system, with sourcing from both the Katy and Tres Palacios gas supply hubs.
