US supermajor Chevron has handed Australia’s Worley an engineering and procurement services contract for the tie-back of the Ballymore oil and gas field, in the US Gulf of Mexico.

Worley confirmed Monday it had been handed the contract to provide brownfield modification services at one of Chevron’s deep-water production facilities in the Gulf of Mexico.

The contract will see Worley provide engineering and design services for the integration and subsea tieback of Ballymore, with the Australian company supporting both the subsea and topsides designs, while adding it will also provide procurement services for topsides.
