The scope included piggy-back pipelay in S-lay mode (18-in. plus 4-in. lines) in around 4,265 ft (1,300 m) water depth, using the derrick lay vessel, DLV 2000; and installation with other vessels of 6-in. lines, pipeline end terminations (PLETs) and manifolds in water depths of close to 6,300 ft (1,920 m).
In addition, the company installed what it claims is India’s longest dual riser.
The offshore environment was challenging, with disruptions from two cyclones, according to Ian Prescott, senior vice president for Asia Pacific.
For the second offshore campaign McDermott will install further manifolds, manifold piles, pipelines, PLETs, jumpers and umbilicals in ultra-deepwater depths, also performing modifications to Reliance’s existing control and riser platform.
All work on the KG-D6 R-Cluster is expected to finish during 2Q 2020, while the Satellite cluster development, which was awarded as a separate contract last July, is scheduled for completion in early 2021.
