WorleyParsons will be the preferred global provider of technical, project and operational support services to our customers, using the distinctive WorleyParsons’ culture to create value for them and prosperity for our people.

The history of WorleyParsons is woven around the vision and energy of its founder and current Chief Executive Officer John Grill, when, in 1971, he founded a small Australian engineering consultancy called Wholohan Grill and Partners. 

Wholohan Grill and Partners grew steadily throughout the 1970’s and ‘80’s and in 1986 acquired the Australian and Asian interests of Worley, an American based engineering firm with a strong reputation in the offshore gas and oil arena.

The company changed its name to Worley and from this point began expanding steadily, securing long term contracts in Brunei, Malaysia, Thailand and Singapore, and creating local joint ventures, most of which are still active today. The partnering model Worley used was based on mutual respect and the understanding that local partners provided the essential knowledge to develop their regional markets. These principles still prevail today in the ongoing growth of the firm and are very much the culture of the organization.
Throughout the 1990’s Worley expanded both its industry sector and geographical footprint. 

In 2004 Worley acquired Parsons E&C, a global leader in downstream hydrocarbons with a widely recognized reputation for its high quality project services to the Power, Oil and Gas, Refining, Petrochemicals and Chemicals sectors globally. Parsons E&C has its own impressive history stemming back to 1944 when Ralph M. Parsons started what is now the Parsons Corporation in Los Angeles. In 2002, Parsons Corporation separated Parsons E&C from the other business units. In recognition of the strong and successful heritage of both firms, Worley merged operations with Parsons E&C and commenced trading as WorleyParsons.

Today, the global enterprise has 120 offices and 28,800 personnel. WorleyParsons’ commitment to entrepreneurial spirit and partnership, started by John Grill at Wholohan Grill and Partners over 30 years ago, still drives the company towards its vision to be the preferred global provider of technical, project and operational services to our customers, using our distinctive culture to create value for our customers and prosperity for our people
