Master Boat Builders and Sterling Shipyard to build four tugboats for Gulf LNG tugs of Brownsville
Gulf LNG Tugs of Brownsville, LLC (Gulf LNG Tugs) today announced the signing of two construction contracts with Master Boat Builders, Inc. (Master Boat) and Sterling Shipyard, LLC (Sterling) for each shipyard to construct two tugs to serve the Rio Grande LNG export facility (RGLNG), which has commenced construction in Brownsville, Texas.
In consultation with RGLNG, Gulf LNG Tugs selected Master Boat and Sterling after a rigorous bid process.
Each shipyard will construct two Z-Tech 30-80 tugboats designed by naval architect Robert Allan Ltd. These 30-80s represent a proven workhorse in Gulf Coast ports, where affiliates of Gulf LNG Tugs already operate 10 of the same hull design. The tugboats will meet U.S. Coast Guard Sub-M regulations and will be classed through the American Bureau of Shipping (ABS). The main propulsion engines are Caterpillar 3516 E, complying with EPA Tier-4 emission standards, and the tugs will receive ABS low emission vessel notation. Main engines are connected to Schottel SRP 510 FP-Z drives fitted with 2.8-meter propellers. The tugs are fitted with a Markey DEPSF-48-100 HP Electric Class III hawser winch, providing full bollard pull performance Render-Recover feature.
The new tugboats will have an overall length of 98.5 feet, beam of 42.7 feet, and a bollard pull of 80 metric tonnes. Additionally, each tug will be equipped with firefighting capabilities to meet the ABS Fire Fighting Class 1 (FiFi 1) classification.

It is owned by Bay-Houston Towing Co., in Houston, Texas; Moran Towing Corporation, in New Canaan, Connecticut; and Suderman & Young Towing Company, in Houston, Texas.
