Worley awarded services contract for Phillips 66 renewable fuels project

Worley has been awarded a front-end engineering services contract by Phillips 66 Company (Phillips 66) to convert its San Francisco refinery in Rodeo, California, USA into a renewable fuels-manufacturing facility.

The project will reconfigure the refinery and produce up to 2.5 billion litres (650 million gallons) per year of renewable transportation fuels from used cooking oils, fats, greases and vegetable oils. Once built, the renewable fuels facility is expected to be one of the world’s largest facilities of its kind.

Under the contract, Worley will provide front-end engineering design services for the facility, which will be executed by Worley’s North America West team with support from Worley’s Global Integrated Delivery team.

“As a global company headquartered in Australia, this project aligns with our strategic focus on sustainability and delivering a more sustainable world. We are pleased that Phillips 66 has engaged Worley in this important renewable fuels project and look forward to supporting Phillips 66’s energy transition goals, while also supporting Worley’s strategic focus on future fuels,” said Chris Ashton, Chief Executive Officer of Worley.

Authorised for release by Nuala O’Leary, Group Company Secretary.
