Worley Limited is an Australian engineering and professional services company which provides consulting and project delivery expertise to the resources and energy sectors, and complex process industries.

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.

At the start of the new millennium, Worley was well poised to continue its industry sector and geographic expansion with 30 offices and 3,000 personnel globally.

That provided a significant expansion of the organisation's ability to support its customers in the areas of water and environmental services.

[9] WorleyParsons also developed its business in Africa,[10] with the establishment of offices in Egypt and Libya, joint venture in Nigeria as DeltaAfrik with Delta Tek Engineering and by the 2008 acquisition of a 50% share in Pangaea – a Pretoria-based project services company, which was renamed PangaeaWorleyParsons.

[11] The acquisitions of SEA Engineering[12] in 2007, and INTEC (now known as INTECSEA) in April 2008,[13] both international offshore deep-water hydrocarbons engineering and project services companies, strategically positioned the company to provide large-scale integrated deep-water facilities, subsea and marine systems projects.

[16] Operating in Australia and China, Evans & Peck provide services across the transport, power and energy, resources, water and social infrastructure sectors.

In 2014, WorleyParsons acquired MTG, Ltd., an American management consulting firm in the oil and gas, petrochemicals and chemicals industries with operations in North America, the United Kingdom and Australia.
