Background
As one of the busiest ports in the United States, the Port of Long Beach serves as a major gateway for trans-Pacific trade and logistics. Beneath this vital maritime hub runs a complex network of critical utilities including fuel, water, and communications lines that must remain secure and operational around the clock. To expand capacity and improve redundancy, new pipelines were required under the active port and adjacent naval base—an area where conventional open-cut construction methods were impossible. These pipelines were installed by a separate contractor using long horizontal directional drills, many extending more than 3,000 feet beneath the port and ocean floor.
Solution
After the new HDD-installed steel pipes were in place, United Pipeline Systems was contracted to install Tite Liner® inside these critical lines. This phase marked United’s third major project at this location. United’s scope included installing Tite Liner® in both direct-to-service lines such as oil and other product pipelines, and carrier pipes that would house additional utilities. The newly constructed pipes varied in diameter and purpose, supporting essential functions such as fuel transfer, water injection, oil gathering, and fiber-optic communications. By lining these long HDD bores with Tite Liner®, United provided a high-performance internal corrosion- and abrasion-resistant barrier designed to dramatically extend pipeline service life.
Results
United’s Tite Liner® installation delivered a durable, long-term protection system for the port’s new underground infrastructure. The liner creates a continuous, tight-fit barrier inside the steel pipe, preserving structural integrity while safeguarding the critical product and carrier lines within.
With this latest phase successfully completed, the Port of Long Beach now benefits from enhanced reliability, increased capacity, and significantly improved long-term durability across its essential utility network, without additional excavation or disruption to port operations.
