McDermott International has completed installation and pre-commissioning for Reliance Industries’ R Cluster subsea field in the KG D6 block.

The KG-D6 block lies in the Krishna-Godavari basin of the Bay of Bengal off the eastern coast of India.

For the R Cluster project, McDermott built a yard facility in India for the fabrication of risers and jumpers, as well as the provision of marine logistics support.

McDermott Asia Pacific senior vice-president Ian Prescott said: “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.

“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.”

There are two offshore campaigns for the project.

During the first campaign, the DLV 2000 vessel completed the company’s first piggy-back pipelay in S-lay mode in a water depth of 1,300m.

Furthermore, the vessel performed its first installation of an ultra-deepwater structure weighing 343t, along with various 6in pipelines, pipeline end terminations (PLETs), as well as manifolds in up to 1,965m-deep water. The company claims this as India’s longest dual riser.

The second campaign involved the installation of manifolds, manifold piles, flowlines, PLETs, jumpers and umbilicals in ultra-deepwater depths and modifications to Reliance’s control and riser platform.

Recently, McDermott secured a contract from Qatargas to deliver FEED services for Qatar Petroleum’s North Field South (NFS) project.
