The project update was shared on Wednesday by the U.S.-based engineering, procurement, construction, and installation company, McDermott.

The contract for  ONGC’s largest deepwater project, the development of block DWN-98/2 in the Krishna Godavari basin, was awarded to Baker Hughes, McDermott, and Larsen & Toubro in October 2018.

According to McDermott, it was the largest ever subsea equipment deal in India.

McDermott said on Wednesday that the integrated subsea package includes the supply of all subsea production systems (SPS), including 26 deepwater trees, and the installation of subsea umbilicals, risers and flowlines (SURF) at a water depth of between zero to 4,265 feet (1,300 meters).

Early first gas involved the tie-back of a single well to the existing Vashishta facility. At 4,265 feet (1,300 meters), the first well that has been opened for early first gas is the deepest water depth opened by ONGC.

“McDermott is a leader in the subsea space and we have worked incredibly hard to fast-track the production to early first gas,” said Ian Prescott, McDermott’s Senior Vice President for Asia Pacific.

He added: “Production from a deepwater well in less than 14 months is an outstanding achievement for the deepwater exploration and production industry.

“In line with the ‘Made in India’ approach for the 98/2 project, a substantial amount of engineering and project management has been led from McDermott’s operations in Chennai. This local approach is a new initiative in the deepwater subsea space for McDermott.”
