Strike Pioneers First-of-Its-Kind Pipe-in-Pipe Installation on Gulf Coast with Enbridge
(P&GJ) — Strike, a leading provider of pipeline, facilities, and energy infrastructure solutions, recently completed a groundbreaking project along the Gulf Coast that set a new standard for complex pipeline installation.
In what is believed to be the first project of its kind, Strike performed the engineering, procurement, and installation of approximately 13,000 linear feet of 16-inch pipeline inside an existing 20-inch pipeline, converting the larger pipe into a casing.
The project included a 9,950-foot segment under Nueces Bay, as well as a 3,550-foot segment beneath the Corpus Christi Inner Harbor Channel. The two cased sections were connected via a 750-foot section of in situ replacement. This unique pipe-in-pipe solution allowed the team to minimize impacted areas and greatly reduce the schedule demands of permitting and executing a new HDD crossing.
“When the client first approached our team with the challenge, our engineering and construction teams immediately went into problem-solving mode. The preparation and teamwork demonstrated by both Enbridge and Strike illustrated how much can be accomplished when you operate with full transparency,” said Tanner Patterson, Senior Vice President of Regional Operations at Strike.
“This unique project wasn’t without its challenges, such as ensuring the new pipe and bumpers could be safely and effectively installed over such a long distance, given the existing HDD profile. Working alongside our client and leveraging our network of vendors, the team overcame these issues and ultimately completed the project on schedule. Our internal engineering and construction teams worked alongside the client throughout a challenging permitting and design process. Additionally, we aided in developing a unique solution to address long-term viability through the design and implementation of a cathodic protection system. Most importantly, the project was completed without any safety incidents.”
“Substantial technical due diligence was completed by our highly specialized teams and determined the pipe-in-pipe solution was right for our circumstances,” added Chris Boozer, Director, USGC Engineering and Projects at Enbridge. “This solution allowed Enbridge to minimize impact to our customers and will serve as a successful benchmark for our industry. This project’s success is directly attributed to the hard-working and dedicated project teams from Enbridge and Strike.”
Strike’s Gulf Coast and Engineering teams earned high praise for their prompt action, collaboration, precision, and unwavering commitment to safety, delivering a solution that redefines what’s possible in pipeline construction beneath critical waterways.
