McDermott International, Ltd has completed the KG-D6 R Cluster subsea field development project and achieved pre-commissioning and ready for startup for Reliance Industries Ltd., in the Krishna Godavari Basin, located off the east coast of India.

"The safe and successful completion of Reliance's KG-D6 R Cluster project is a testament to McDermott's subsea experience in the Bay of Bengal," said Ian Prescott, McDermott's Senior Vice President, Asia Pacific. "Pre-commissioning and ready for startup was achieved despite difficult circumstances—two severe cyclones during the first campaign and, in the second, navigating the challenging conditions of COVID-19. It is an outstanding achievement and demonstrates McDermott's commitment to reliable execution."

For the KG-D6 R Cluster project, McDermott built a yard facility in India for the fabrication of risers, jumpers and marine logistics support. The project comprised two offshore campaigns. During the first campaign, the DLV 2000 completed McDermott's first piggy-back pipelay in S-lay mode (18-in. plus a 4-in.) in 4265 ft (1300 m) water depth. It also included the installation of the first ever ultra-deepwater structure, weighing 343 t, for the DLV 2000. Several 6-in. pipelines, PLETs and manifolds were installed in water depths up to 6447 ft (1965 m). In addition, McDermott installed India's longest dual riser.

The second campaign included installation of manifolds, manifold piles, flowlines, PLETs (S-mode and J-mode), in-line structures, jumpers and umbilicals in ultra-deepwater depths, together with major brownfield modifications to Reliance's control and riser platform. Successful flowline and umbilical installation were completed in 6561 ft (over 2000 m) water depth using McDermott vessels: DLV 2000; Lay Vessel 108; North Ocean 102.
