Buffalo Marine Service

What Buffalo Marine Service does

Buffalo Marine Service, Inc. is a privately held, family-owned marine transportation and bunkering company founded in 1935 and headquartered at 8201 E. Erath in Houston, Texas. The company operates inland towing vessels and tank barges along the Gulf Coast inland waterway corridor from Corpus Christi, Texas to Mobile, Alabama, serving commercial maritime, energy, and petrochemical customers. Its fleet consists of four named towing vessels (M/V San Roberto, M/V CJ Studdert, M/V Nancy Marian, and M/V Lt. Dick Dowling) and 33 tank barges organized into the Buffalo series (250-807, Star) and Shamrock series (301, 500-502, 900-905), with the Shamrock 900 series specifically noted as asphalt-capable. Barges range in capacity from 8,401 to 28,858 barrels and are equipped with Positive Displacement and Coriolis flow meters in 3-inch through 8-inch sizes for precise cargo measurement.

The company's core technology stack centers on its USCG-compliant fleet, modern communication systems, and a 24/7 shoreside command center that maintains continuous contact with all vessels for real-time fleet coordination. Professional crews of wheelmen, tankermen, and deckhands operate on a 14/7 (two weeks on, one week off) schedule. Buffalo Marine is led by CEO Patrick Studdert and President Tim Studdert, with additional senior leadership including CFO Tara Battle, General Counsel & VP Tom Marian (named 2026 Maritime Leader of the Year by the Greater Houston Port Bureau), VP of HSE Patrick Little, and a full shoreside support organization.

Buffalo Marine generates revenue through contract-based B2B marine services, including tank barge transport, cargo loading and discharging, and bunker services for vessels operating in the Gulf Coast region. Pricing is quote-based and not publicly disclosed, structured around multi-year service agreements tied to specific voyage parameters and customer requirements. The company maintains a minimal digital marketing presence (company website and Facebook) and relies primarily on direct enterprise sales relationships, long-tenured customer relationships, and industry reputation built over nearly 90 years of continuous operation.
