The PRP2 (Pipeline Replacement Project 2) was the highest valued contract ever awarded by ONGC, India’s leading upstream oil and gas company.

Leighton’s scope of work consists of full engineering, procurement, fabrication and installation of 178 km of rigid pipelines, 54 km flexible pipelines and 78 nos of platform topside modifications spread over three seasons.

PROJECT SCOPE
Leighton has over 35 years experience as Asia’s largest project developer and construction contractor operating in countries such as Malaysia, Indonesia, Singapore, Brunei and Sri Lanka. Its offshore industry represents a key area of growth for the Group.

The company operates a fleet of state-of-the-art marine equipment suited for the full range of offshore and subsea construction works in water depths up to 150m, and is the region’s pre-eminent SPM installation contractor.

In the first season for the PRP2, Leighton completed 51 km of rigid pipelines, 18 km of flexible pipelines and 18 nos of platform modifications between October 2008 and May 2009.

Due to the large volume of work, Leighton mobilized marine spread as early as September 2009 to assure timely completion of the second season. The scope of work covered some 81 km of rigid pipelines, 17 km of flexible pipelines and 40 nos of platform modifications, including 11 modifications at large offshore production complexes.

KEY MILESTONES
During the season two campaign, Leighton amassed a number of outstanding achievements. Leighton’s modern purpose-built barge, Eclipse, successfully laid 235 joints (2800 m) of rigid pipe in one 24 hour period, topping the record for pipe laid in a single day by any contractor in ONGC fields in India. Leighton Eclipse went on to set field records for riser installation by stack-on method within and riser removal.

Leighton also registered records for laying 2700 m of flexible pipeline in a single day and for the highest number of platform modifications completed in a single season by any contractor.

At peak, Leighton had a total of 34 vessels and around 1200 men offshore during Season 2. The project also achieved over 4.4 million man-hours without LTI and received a number of awards for its safety performance.

Senthil Kumar, PRP2’s Senior Project Manager, described the success of the project to date, “It has been an exceptional team effort that included extensive in-depth planning, preparation and coordination.

“The team has now kicked off the preparations for season three and we expect even better results this year,” he said.

CEO of Leighton India’s Oil and Gas division, Jignesh Dersari added: “This project is a testament to the capability and capacity of Leighton to successfully deliver even the most challenging projects.

“Our India business continues to grow and we continue to build a strong client base through successful project delivery.”
