BP and energy servicer Worley have formed an alliance to improve capital efficiency for BP’s global site projects, cementing a decade-long venture for the companies, according to a June 10 press release.

The collaboration, BP’s operating business’ first alliance, plans to save an initial estimated $40 million over two years across BP’s sites where Worley holds a service contract.

Locations include the Gulf of Mexico, Oman, Mauritania and Senegal oil and gas producing regions, the U.S.’ Cherry Point and Whiting refineries and the Rotterdam, Gelsenkirchen and Lingen European refineries.

Earlier this year, Worley signed a five-year global framework agreement to provide engineering, procurement and construction (EPC) management services for BP’s global refinery assets and new energy initiatives. Worley holds EPC contracts across BP’s legacy upstream businesses.
