WSP | PARSONS BRINCKERHOFF HELPS ACHIEVE FAST-TRACK COMPLETION OF UNDERGROUND STORAGE CAVERNS IN TEXAS

Phase 1 of the Phillips 66 Clemens Cavern Terminal in southern Texas for storage of natural gas liquids (NGLs) has been completed. WSP | Parsons Brinckerhoff provided engineering, procurement and construction management (EPCM) services.

 

HOUSTON, TX – Phase 1 of the Phillips 66 Clemens Cavern Terminal in southern Texas for storage of natural gas liquids (NGLs) has been completed. WSP | Parsons Brinckerhoff provided engineering, procurement and construction management (EPCM) services.

The Phase 1 elements form a substantial portion of the overall facility, and their completion brings Phillips 66 closer to its goal of expanding the production and export of LPGs. The project involved drilling of five storage cavern wells and six brine disposal wells, design and construction of a 12,000-horsepower leaching plant and associated infrastructure, initial solution mining of the first three caverns, and construction of a 1.2-million-barrel brine pond.

WSP | Parsons Brinckerhoff executed Phase 1 on a highly accelerated schedule. The leaching plant was designed and built in five and one-half months, which is less than half the time normally required. Six months later, the caverns had been solution mined, tested and delivered, allowing Phillips 66 to begin the process of storing NGLs. WSP | Parsons Brinckerhoff also provided quality assurance/quality control services during construction.

“We are the leader in the design and construction of storage caverns and associated surface facilities,” said Roger Blair, president of the Industrial and Energy sector for WSP | Parsons Brinckerhoff in the U.S. “The Clemens Terminal project, which has successfully moved ahead in spite of bad weather and a very aggressive schedule, shows why we’re the firm of choice for many clients.”

WSP | Parsons Brinckerhoff will continue to support Phillips 66 during Phase 2, which will involve completing the leaching of all caverns to final size by the end of 2016, as well as the construction of a second, three-million-barrel brine pond. The caverns will eventually be used for storage of propane, butane and Y-Grade (raw mix).
