Gulf Companies (GIE) acquires WSP USA’s Underground Storage Business

Gulf Companies (Gulf Interstate Engineering) announced the acquisition of WSP USA’s Underground Storage Business (UGS), a move that strengthens Gulf’s position in underground energy storage and subsurface infrastructure.

UGS is widely recognised as a leader in underground storage, with a team of about 120 experts and more than 50 years of experience. They have played a key role in the design and delivery of over 300 cavern projects across the US, including salt and hard-rock caverns used to store natural gas, NGLs, petroleum products, and emerging energy resources. Their deep technical knowledge spans cavern design, drilling, operations, and long-term maintenance. Bringing WSP USA’s UGS into Gulf Companies expands Gulf’s capabilities and supports its long-term growth in core energy markets.

By combining Gulf’s strength in surface facilities with UGS’s unmatched underground expertise, Gulf Companies is better positioned to take on larger, more complex projects and deliver integrated solutions across the energy value chain. “Our teams are a natural fit,” said Kent Wilfur, President & CEO of Gulf Companies. “Together, we’re building something truly special for the future of energy infrastructure.” The UGS team will continue leading in underground storage while growing into new markets as part of Gulf Companies.
