Client: Petroleum Development Oman

Project value: US$1.25 billion

Location: Harweel Cluster, southern Oman

The Rabab Harweel Integrated Project (RHIP) is the largest development in Petroleum Development Oman’s (PDO) portfolio. Petrofac is providing engineering, procurement, construction management and commissioning support services worth US$1.25 billion.

Unlike most other oil and gas projects in the Middle East, RHIP is not being delivered on a lump-sum turnkey basis. Instead, Petrofac is providing its services on a reimbursable basis with incentives. This means Petrofac’s profit is linked to the achievement of specific milestones and a potential gain share on procurement.


Located in the Harweel Cluster of fields, deep in the desert in the south of the Sultanate, the RHIP facility will include sour gas processing facilities and associated gathering and injection systems and export pipelines. It will handle the production of oil and gas from the Harweel oil reservoirs via miscible gas injection and the production of gas with condensate from the Rabab reservoir through partial recycling of sour gas.

When complete, the facility will deliver:

  • 6 MM SCMD of sweet gas
  • 60,000 BPD of oil
  • 16 MM SCMD of high pressure sour injection


The project has a total workforce of around 4,500. This includes around 600 Petrofac employees working on the project.

In-country value

Delivering in-country value is key to our success for the RHIP development and our commitment to supporting the sustainable future of Oman.

We have exceeded all of our targets for Omanisation, with 27 Oman nationals employed in the Muscat office and 12 onsite. More than a third of the project’s total procurement value was sourced within Oman.

At the time of award, RHIP was the first project to be undertaken in Oman by Petrofac on a reimbursable and incentivised basis. In addition to safe project execution, we have, over the course of the contract, focused on returning significant value to PDO through leveraging our extensive procurement and supply chain capabilities.  We have also directly transferred the experience gained on RHIP in support of our second in-country EPCm project, Yibal Khuff.

Project update: June 2017

Engineering is now complete and procurement 93% complete. We have also achieved several other significant project milestones, including:

  • 3 million man-hours spent on engineering, procurement and construction without an LTI
  • 2 million man-hours spent on fabrication without an LTI
  • Fabrication of 29,000 metric tonnes of structural steel
  • More than 90% complete on the fabrication of 800,000 dia inch of piping
  • Delivery and precise installation of 67 pre-assembled rack (PAR) modules, representing more than 9,600 metric tonnes of fabrication and 2.3 km of linear pipe rack

The delivery of the PAR modules marked a key achievement for the project team. Because of the remote site location, and the high sour content of the gas, we set out to minimise the construction man-hours on site. To do this, we decided to pre-assemble the pipe racks offsite and transport them in their finished form. This was a first in Oman and was a significant part of the project strategy.

The logistics surrounding the transportation of the modules was complex. They were transported 600km by sea and 560 km by road. Despite the 9-metre wide payloads, and a total of 75,000 km driven, there was not a single safety incident. Once onsite, everything fitted together with millimetre precision and with no re-work required. This involved a huge collaborative effort between PDO, Petrofac, the fabricators, logistics experts, the Royal Omani Police and the construction contractor.
