Worley Secures Engineering Services Contract for Petro Rabigh Complex in Saudi Arabia

Worley has secured a new role on one of the region's most significant refining and petrochemicals sites, with Petro Rabigh selecting the Australian-headquartered services company to support its future project portfolio at the integrated Rabigh complex in Saudi Arabia.

The announcement was made by Worley on October 28, 2026, and confirms that the newly awarded agreement covers engineering and project management services for refining and petrochemicals projects yet to be developed at the site.

Worley extends Petro Rabigh partnership

The award extends a commercial relationship that Worley says stretches back to 2017, when the company first began supporting Petro Rabigh.

According to the announcement, Worley has worked alongside the Saudi Arabian producer for years and now looks forward to continuing its contribution to the development of what it describes as one of the region's leading refining and petrochemical complexes.

Mohammed Alwazzan, Senior Vice President at Worley, commented on the selection, saying, "We are pleased to continue supporting Petro Rabigh as it advances its future project portfolio. This award combines Worley's local delivery capability in the Kingdom with the specialist expertise of our global network, enabling us to provide integrated engineering and project management services that support the safe, efficient, and sustainable development of refining and petrochemical infrastructure."

What the contract covers across the project lifecycle

Under the terms of the agreement, Worley's remit extends across the full development and delivery cycle of projects within Petro Rabigh's portfolio. The company will deliver engineering, project management, procurement support, and related consultancy services.

Specifically, the scope includes developing design basis scopes, conducting technical evaluations, and preparing cost estimates. Worley will also support front-end engineering design, commonly known as FEED, through the preparation of bid packages.

As individual projects move from concept toward construction, the company will provide detailed engineering and execution-phase support, working with Petro Rabigh as its developments progress through study, design, and delivery.

Worley stated that it will provide these integrated engineering and project management services by drawing on capabilities from within Saudi Arabia as well as its global network, matching resources to project requirements as they arise through each phase of development.

Potential new facilities and infrastructure in scope

The services under the agreement are directed at the evaluation and development of potential new facilities and infrastructure across the Rabigh complex. The range of assets identified in the announcement includes process units, utilities, sulfur recovery facilities, and associated infrastructure.

According to Worley, the work will help Petro Rabigh advance its future projects, which are aimed at enhancing the long-term value and performance of the company's refining and petrochemicals operations.

No project values, capacities, or timelines were disclosed in the announcement.

Context within Worley's chemicals and fuels business

The announcement was published by Worley under its chemicals and fuels news stream. That stream also highlights the company's Full Project Delivery offering, alongside Worley Consulting solutions, positioning the Petro Rabigh award within the broader suite of services the company markets to refining and petrochemicals clients.

Worley's involvement in the Kingdom extends beyond project delivery. In related news carried alongside the announcement, Worley Saudi Arabia has earned Great Place to Work Certification.

The company says this recognition reflects the positive workplace culture shaped by its people across the Kingdom, underscoring the local presence that the company cites as a differentiator in its delivery model for Saudi clients.

A complex serving refining and petrochemicals side by side

Petro Rabigh operates an integrated refining and petrochemicals complex at Rabigh on Saudi Arabia's Red Sea coast, and the newly announced agreement is structured to serve both sides of that operation.

The dual focus is reflected in the scope described by Worley, which spans potential refining-adjacent process units as well as petrochemicals facilities, supported by utilities and sulfur recovery infrastructure. The selection of an existing partner for this next phase of development suggests a continuation of how Petro Rabigh has approached project support in recent years.

Worley combines local expertise with global capabilities

Worley's statement emphasised continuity rather than a new beginning, noting that it has been involved at the complex since 2017 and intends to keep contributing as the operator's future portfolio takes shape. For Worley, the award reinforces its strategy of pairing in-Kingdom delivery capability with specialist expertise drawn from its worldwide network.

Alwazzan's comments framed the arrangement explicitly in those terms, pointing to the combination of local resources and global knowledge as the basis for supporting what he described as the safe, efficient and sustainable development of refining and petrochemical infrastructure.

Supporting the Petro Rabigh project development

For Petro Rabigh, the agreement provides access to engineering, procurement support, and project management capacity as it evaluates and develops potential new facilities at the complex.

The company has not publicly detailed which specific projects will proceed, but the scope of Worley's services, from design basis development and technical evaluations through FEED bid package preparation and detailed engineering, indicates support that begins well before final investment decisions and continues into execution.

Neither party disclosed the commercial value of the agreement or the duration of the engagement in the October 28, 2026 announcement.

Further details on the specific facilities to be evaluated under the contract have also not been released, beyond the categories of process units, utilities, sulfur recovery facilities, and associated infrastructure named by Worley.
