McDermott International said it was able to mitigate impact of two cyclones en route to completing the first of two offshore campaigns for Reliance Industries Ltd. KG-D6 R-Cluster subsea field development, in the Krishna Godavari Basin, located off the East Coast of India.
The recently completed campaign included McDermott’s piggy-back pipelay in S-lay mode (18-inch plus a 4-inch) offshore in India in approximately 1,300 meters water depth and the installation of 6-inch lines, pipeline end terminations (PLETs) and manifolds to water depths of approximately 1,920 meters, McDermott said. The company used its derrick lay vessel, DLV 2000 to perform its first S-lay piggy-back pipelay, and other vessels were also used to complete subsea installation activities. In addition, McDermott also 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,” said Ian Prescott, Senior Vice President for Asia Pacific. “We will build on our success to help ensure the second campaign is accomplished safely with the highest quality.”
The second offshore campaign includes the installation of manifolds, manifold piles, pipelines, PLETs, jumpers and umbilicals in ultra-deepwater depths, together with major brownfield modifications to Reliance’s’ control and riser platform. The contract with Reliance on KG-D6 R-Cluster, which McDermott said is worth between $250 million and $500 million, is scheduled for completion in the second quarter of 2020. The satellite cluster development was awarded as a separate stand-alone contract in July 2018, and is scheduled for completion in the first quarter of 2021.
McDermott said it continues to expand its operations in India, with more than 1,500 personnel across offices in Gurgaon, Chennai, Pune and Mumbai. The Chennai and Gurgaon offices support a range of front-end engineering design (FEED) to engineering, procurement, construction and installation global projects (EPCI).
