WorleyParsons provides a comprehensive range of refinery services through all project phases and has been doing it for over 60 years. Our experience in grassroots, revamp and expansion projects, both locally and globally, allows us to provide our customers with optimal project delivery solutions for their refineries.

The Industry
Maintaining and optimizing existing assets is becoming an increasingly higher priority for refiners as they are affected by new developments for upgrading units and by the introduction of unconventional feedstocks. 

WorleyParsons helps our customers succeed in this dynamic and competitive business environment by supplying innovative, cost-effective and safe project solutions. We’re a leader in delivering these solutions in a way that meets the latest government mandates for clean fuels and exceeds the expectations of our customers around the world.

Over the last 20 years we have been modernizing refineries--enabling customers to maintain plant efficiency, throughput and margins while effectively managing the increasing amounts of sulphur production from generally heavy, sour feedstocks. In all project phases, we focus on the optimization of common critical issues such as budget, schedule, quality, operating reliability and technical integrity.

The technical integrity delivered with our refining projects stems from our technological neutrality. WorleyParsons’ specialist front-end business line, Select, is comprised of concept strategy specialists that develop business models and financial analysis prior to FEED. This conceptual review includes the evaluation of technologies, which ensures that the final recommended solution maximizes investment return and underlying confidence.  

Our ability to deliver refining projects locally with global capabilities and resources is driven by our high-value project delivery centers in California and London. Through our proven workshare processes, customers around the world have access to the cumulative knowledge gained from over 60 years of refining EPCM experience, and from our delivery of over 2,100 refining and petrochemicals projects worldwide.
