McDermott Executes First KG-D6 R-Cluster Campaign

McDermott has completed the first of two offshore campaigns for Reliance KG-D6 R-Cluster subsea field development, in the Krishna Godavari Basin, located off the East Coast of India.

The campaign included McDermott’s piggy-back pipelay in S-lay mode (18-inch plus a 4-inch) offshore India in approximately 1,300 meters water depth and the installation of 6-inch lines, PLETs and manifolds to water depths of approximately 1,920 meters.

McDermott used its derrick lay vessel, DLV 2000 to perform its first S-lay piggy-back pipelay. 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 brownfield modifications to Reliance’s control and riser platform.

The contract with Reliance on KG-D6 R-Cluster is scheduled for completion in the second quarter of 2020.

Satellite cluster development, which was awarded as a separate stand-alone contract in July 2018, is scheduled for completion in the first quarter of 2021.
