08 October 2018

Baker Hughes, a GE company (BHGE), McDermott International, Inc. (MDR) and L&T Hydrocarbon Engineering (LTHE), a subsidiary of Larsen & Toubro, were awarded the subsea contract for India’s Oil & Natural Gas Corporation’s largest deep-water project, the development of block DWN-98/2 in the Krishna Godavari basin. The project brings together leading subsea equipment and services from BHGE, MDR and LTHE to provide ONGC with end-to-end project delivery.

Largest deep-water project

The integrated subsea package includes the supply of all subsea production systems (SPS), including 34 deep-water trees, and the installation of subsea umbilicals, risers and flow-lines at a water depth of between 984 feet and 10,500 feet.

BHGE’s scope will include subsea hardware including trees, manifolds, controls, connection systems, SPS installation tools and services, as well as flexible risers and flow-lines, umbilical and topside controls. BHGE will also provide the pre-commissioning services for additional phases of the project.

McDermott will be responsible for transportation and installation of SURF and SPS facilities using its engineering and other key resources in Kuala Lumpur, Malaysia and Chennai, India as well as its installation assets Derrick Barge 30, Lay Vessel North Ocean 105 and Lay Vessel 108.

The project is one of the first major deep-water developments in India and a milestone for realizing India’s domestic energy potential. Built on an agreement signed in 2016, LTHE and BHGE will fabricate manifolds for the first time in India as part of this project. Delivery is scheduled for 2020 for the gas system and 2021 for the oil system.
