McDermott International , Inc. reported Tuesday that it has completed the first of two offshore campaigns for Reliance Industries Ltd.’s KG-D6 R-Cluster subsea field development, which is located in the Krishna Godvari Basin offshore India.

According to McDermott, the first campaign included:

  • Performing a piggy-back pipelay in S-lay mode (18-inch plus a four-inch) in approximately 4,265 feet (1,300 meters) water depth
  • Installing six-inch lines, pipeline end terminations (PLETs) and manifolds to water depths of approximately 6,300 feet (1,920 meters)
  • Installed India’s longest dual riser

“The safe completion of season one activities, in the challenging offshore environments off the East Coast of India and mitigated disruptions from two cyclones, demonstrates McDermott’s expertise in engineering and execution of complex subsea projects in ultra-deepwater depths,” Ian Prescott, McDermott’s senior vice president for Asia Pacific, said in a written statement emailed to Rigzone. “We will build on our success to help ensure the second campaign is accomplished safely with the highest quality.”

McDermott stated the first offshore campaign occurred at a time when the company is expanding its India operations, with more than 1,500 personnel in offices in Gurgaon, Chennai, Pune and Mumbai. The second offshore campaign in McDermott’s KG-D6 R-Cluster contract with Reliance – ranging in value from US$250 million to US$500 million – calls for:

  • Installing manifolds, manifold piles, pipelines, PLETs, jumpers and umbilicals in ultra-deepwater depths
  • Making major brownfield modifications to Reliance’s control and riser platform

In its written statement, McDermott noted that the second campaign is set to conclude during the second quarter of 2020. The company added that it expects to complete the satellite cluster development under a separate stand-alone contract in the first quarter of 2021.
