What Third Coast Infrastructure does
Third Coast Infrastructure is a privately-held, Houston-based midstream energy infrastructure company that provides gathering, processing, transportation, and floating production system (FPS) services to upstream oil and gas producers operating in the deepwater Gulf of Mexico. The company owns and operates an integrated system spanning approximately 1,900 miles of natural gas, crude oil, and NGL pipelines; five gas gathering systems; three oil gathering systems; two NGL pipelines; a gas processing plant; and four floating production systems (Delta House, King's Quay, Salamanca, and a 26.5% interest in Perdido) with combined processing capacity of 340 MBbl/d of crude oil and 580 MMcf/d of natural gas across a catchment area exceeding 40,000 square miles in the Eastern Gulf of Mexico. The company is an affiliate of ArcLight Capital Partners, with a 50% minority interest in its offshore subsidiary Lighthouse Super Holdings sold in 2021 to a global infrastructure investor; JP Morgan Chase is also referenced as a backer.
Third Coast generates revenue primarily through fee-based midstream services — gathering, processing, and transportation — under long-term contracts with deepwater producers including Murphy Exploration & Production, Shell Offshore, Occidental Petroleum, and Ridgewood Energy. The go-to-market model is direct enterprise sales to upstream operators, supported by a 24/7 asset monitoring control center, a customer portal (MyQuorum), and a 24-hour emergency hotline. The company has executed multiple Term Loan B facilities totaling over $1 billion between 2024 and 2025, with proceeds used to refinance existing debt, fund FPS acquisitions (Salamanca, Perdido), and distribute dividends to shareholders. In October 2025 the company signed a lease for approximately 20,800 square feet in Houston's Norton Rose Fulbright Tower for a 2026 headquarters relocation, signaling continued organizational scaling.

Third Coast Infrastructure competitors and assessment
Company assessmentDirect peers
- Enbridge Inc. Enbridge operates significant offshore Gulf of Mexico pipeline and platform interests and a broader U.S. midstream portfolio. The most direct peer to Third Coast given parallel offshore pipeline and gathering operations in the same basin.
- Crestwood Equity Partners: Crestwood operates gas gathering, processing, and NGL infrastructure across U.S. basins including GOM exposure. Comparable to Third Coast's combination of gathering, processing, and pipeline assets, with overlapping customer set of upstream producers.
Broad incumbents
- Kinder Morgan: One of the largest U.S. midstream operators with significant natural gas transmission, crude, and NGL pipelines. Overlaps with Third Coast's FERC-regulated gas transmission and crude oil pipeline segments but at a much larger, diversified scale.
- Enterprise Products Partners: Major diversified midstream MLP with extensive natural gas processing, NGL, and offshore platform exposure including Gulf of Mexico operations. Comparable to Third Coast on gas processing and NGL pipeline economics, though vastly larger and more diversified.
- Energy Transfer: Large diversified midstream operator with natural gas, NGL, and crude pipelines across multiple U.S. basins. Overlaps with Third Coast on pipeline and gathering services, particularly NGL and natural gas, though with different geographic mix.
- Williams Companies: Large-scale natural gas-focused midstream operator with extensive gathering, processing, and FERC-regulated transmission. Closely comparable to Third Coast's gas gathering and processing franchise, though Williams is onshore-focused and substantially larger.
- Targa Resources: Leading U.S. NGL and natural gas processor/gatherer with significant Gulf Coast and offshore presence. Comparable to Third Coast on NGL pipeline operations and gas processing economics.
- Plains All American Pipeline: Major U.S. crude oil midstream operator with extensive pipeline and gathering systems, including offshore Gulf of Mexico exposure. Directly comparable to Third Coast's crude oil gathering and transportation business.
Emerging players
- Western Midstream Partners: Mid-cap natural gas and crude midstream operator backed by Occidental Petroleum. Comparable to Third Coast in that it services deepwater-linked producer customers, though focused predominantly in the Permian/Delaware basin.
- Helix Energy Solutions Group: Provider of offshore energy production services including well intervention and decommissioning in the Gulf of Mexico. Adjacent comparator to Third Coast's FPS service model given overlapping Gulf of Mexico customer base and offshore operating expertise.
