Sterling Shipyard Delivers Z-Tech® Tug for Gulf LNG Operations
Sterling Shipyard, LLC has successfully delivered the Laguna Gulf, a powerful new tractor tugboat that strengthens its long-term partnership with Gulf LNG Tugs of Brownsville, LLC. The delivery represents an important milestone for both organizations as demand continues to grow for advanced harbor tugboats capable of supporting liquefied natural gas (LNG) terminals and major ports across the U.S. Gulf Coast. The vessel is designed to provide reliable ship-assist, towing, escort, and emergency response services while meeting the evolving operational and environmental requirements of modern LNG facilities.
The Laguna Gulf is the 13th completed vessel in the highly regarded Z-Tech® 30-80 tractor tugboat series, a design developed by internationally recognized naval architecture firm Robert Allan Ltd. The Z-Tech series has gained a strong reputation worldwide for delivering exceptional maneuverability, high bollard pull, operational efficiency, and enhanced safety, making it one of the preferred tug designs for demanding port and terminal operations.
The vessel has been built specifically for Gulf LNG Tugs of Brownsville, LLC, a joint venture that combines the expertise of three well-established towing companies: Bay-Houston Management, LLC, Moran Towing Corporation, and Suderman & Young Towing Company. Together, these organizations bring more than 400 years of combined experience in ship-assist, harbor towing, and marine transportation services. Their longstanding expertise has made them trusted service providers for some of North America’s busiest maritime facilities.
The Gulf LNG partnership has secured contracts to provide tug services for five LNG terminals located along the U.S. Gulf Coast, a region that continues to expand its role as one of the world’s leading LNG export hubs. As additional LNG production and export capacity comes online, demand for specialized tugboats capable of safely handling large LNG carriers is expected to increase significantly.
Sterling Shipyard views the delivery of the Laguna Gulf as the beginning of an even larger production program. According to company leadership, the vessel represents the first in a substantial orderbook that includes tugboats for multiple LNG projects as well as several additional harbor tugboats.
Harry Murdock, Chief Executive Officer of Sterling Shipyard, described the delivery as a significant achievement for the company and an important step in its continued growth.
He explained that the Laguna Gulf is the first vessel in a production schedule that includes projects supporting three LNG developments in addition to nine other harbor tugboats. Altogether, Sterling Shipyard has 13 vessels currently under contract for delivery through 2029, providing the company with a strong multi-year production pipeline.
The expanding orderbook demonstrates increasing industry confidence in Sterling Shipyard’s ability to deliver high-quality vessels that meet the demanding operational requirements of modern ports, energy infrastructure, and marine transportation customers.
Murdock also emphasized the company’s commitment to supporting customers with dependable and environmentally responsible vessels.
Sterling Shipyard aims to build tugboats that combine high performance with low-emission technologies while maintaining the durability and reliability required for continuous port operations. These vessels are intended to serve LNG terminals and commercial ports throughout North America, where safety, efficiency, and operational uptime are critical.
The Laguna Gulf has been engineered to deliver exceptional performance in challenging harbor environments. Measuring approximately 99 feet in overall length with a 43-foot beam, the tug provides excellent stability and maneuverability while remaining compact enough to operate efficiently around terminals, docks, and restricted waterways.
Powering the vessel is a propulsion system producing approximately 7,000 horsepower, enabling the tug to generate a bollard pull exceeding 80 metric tons. This level of pulling power allows the vessel to safely maneuver some of the world’s largest LNG carriers and commercial ships during docking, undocking, escort, and emergency operations.
High bollard pull has become increasingly important as global shipping fleets continue to grow in size. Modern LNG carriers require precise handling throughout terminal approaches, and powerful escort tugboats play an essential role in ensuring safe navigation within confined harbor waters.
The Z-Tech® 30-80 design offers several operational advantages beyond raw pulling power. Its tractor tug configuration provides exceptional agility, allowing operators to quickly change direction and maintain precise vessel positioning during complex ship-assist operations.
These maneuvering characteristics help improve safety while reducing the time required to move vessels into and out of terminals. Enhanced responsiveness is especially valuable at LNG facilities, where strict operational procedures require reliable vessel control under a wide range of weather and tidal conditions.
Safety has been incorporated throughout the vessel’s design. One of the most notable features is its integrated firefighting capability, which has been built to satisfy the stringent American Bureau of Shipping (ABS) Fire Fighting Vessel 1 (FFV1) classification.
This certification confirms that the tug possesses advanced onboard firefighting systems capable of assisting during marine emergencies involving vessels or terminal infrastructure. Such capabilities provide an additional layer of protection for LNG operations, where emergency preparedness remains a top priority.
Firefighting tugboats serve multiple purposes beyond emergency response. They can support incident containment, provide cooling water to affected facilities, and assist first responders during complex maritime situations. These capabilities have become increasingly valuable as ports continue expanding cargo handling operations and LNG infrastructure.
Environmental performance also plays a growing role in modern tugboat construction. Harbor operators, port authorities, and energy companies are placing greater emphasis on reducing emissions while maintaining operational capability.
Sterling Shipyard has positioned its latest tugboats to address these evolving requirements by delivering vessels designed for efficient operations with lower emissions than previous generations. Such improvements help customers meet sustainability objectives without sacrificing towing performance or reliability.
The delivery of the Laguna Gulf also highlights continued investment in the U.S. shipbuilding industry. Domestic shipyards remain essential to supporting the nation’s maritime transportation infrastructure, energy sector, and commercial shipping network.
Building vessels within the United States strengthens local manufacturing capabilities, supports skilled maritime jobs, and helps ensure that operators receive ongoing technical support throughout a vessel’s service life.
Sterling Shipyard has steadily expanded its reputation as a builder of specialized workboats capable of serving a diverse range of industries, including LNG, commercial ports, offshore energy, and marine transportation. By focusing on quality construction and proven vessel designs, the company continues to secure repeat business from experienced marine operators.
Meanwhile, Gulf LNG Tugs of Brownsville benefits from the combined operational knowledge of its three partner companies. Their extensive experience managing harbor towing operations enables the partnership to deploy vessels efficiently while maintaining high standards for safety, crew training, and operational excellence.
As LNG exports continue expanding along the Gulf Coast, specialized marine support services will remain a critical component of terminal operations. Every LNG carrier entering or departing a terminal depends on highly capable tugboats to safely navigate restricted waterways and docking facilities.
The addition of the Laguna Gulf increases the partnership’s operational capacity while ensuring customers have access to one of the latest generations of high-performance escort tugboats available today.
Looking ahead, Sterling Shipyard’s production schedule through 2029 reflects sustained demand for advanced harbor tugboats supporting North America’s growing maritime and energy industries. Continued investments in LNG infrastructure, port modernization, and commercial shipping are expected to create additional opportunities for specialized vessel construction.
With the successful delivery of the Laguna Gulf, Sterling Shipyard has reinforced its position as a trusted builder of technologically advanced tugboats while further strengthening its relationship with Gulf LNG Tugs of Brownsville. The vessel represents not only another completed project but also the beginning of a broader multi-year fleet expansion designed to enhance the safety, efficiency, and reliability of LNG terminal and harbor operations across the U.S. Gulf Coast.
