ONGC has awarded a consortium of Baker Hughes, a GE company, McDermott International, and L&T Hydrocarbon Engineering (LTHE) the subsea contract for development of block DWN-98/2 in the Krishna Godavari basin offshore eastern India.
This is said to be ONGC’s most extensive deepwater project to date.
The award covers the supply of all subsea production systems (SPS), including 34 deepwater trees, and installation of subsea umbilicals, risers, and flowlines in water depths of 984-10,500 ft (300-3,200 m).
BHGE will provide all the subsea equipment plus pre-commissioning services, with McDermott applying its fleet of pipelay and construction vessels and EPCI capabilities.
By reducing the number of interfaces across the project, the trio aims to reduce complexity, and at the same time improve execution efficiency for the client.
“The project will deliver leading technologies to ONGC across a full subsea scope,” said Neil Saunders, president and CEO, Oilfield Equipment, BHGE.
“As the industry moves toward greater collaboration across the value chain, we believe our technology and our unique commercial models are well-positioned to meet demand for future subsea projects.”
Ian Prescott, McDermott’s senior vice president for Asia Pacific, added: “The consortium will provide an integrated solution that not only takes full advantage of the international expertise brought by BHGE and McDermott, but provides a key made-in-India element by LTHE that represents local capabilities as well.”
BHGE’s scope will include subsea trees, manifolds, controls, connection systems, subsea production system installation tools and services, and flexible risers and flowlines, umbilical and topsides controls. It will also provide pre-commissioning services for additional phases of the project.
McDermott will transport and install all SURF/SPS facilities using its engineering and other resources in Kuala Lumpur, Malaysia and Chennai, India, and the Derrick Barge 30, Lay Vessel North Ocean 105, and Lay Vessel 108.
Following an agreement signed in 2016, LTHE and BHGE will fabricate manifolds for the first time in India as part of the project.
The subsea award is said to be the largest of its type ever awarded by ONGC. Delivery of the gas system is scheduled for 2020 and of the oil system for 2021.
