Fossil Energy – Subsea
Deploying more than 2,000 crew members, McDermott successfully navigated both the challenges of COVID-19 and an active monsoon season to deliver a gas field, known as the U-Field, for ONGC’s KG-DWN 98/2 Block project.
ONGC’s KG-DWN 98/2 Block project, located in the Bay of Bengal off the east coast of India, is the largest and one of the most complex subsea projects in Asia Pacific, involving major subsea infrastructure installation in ultra-deepwater.
McDermott is delivering two gas systems for ONGC’s gas fields—U-Field and R-Field. The project is being executed in a consortium, with Larsen & Toubro Hydrocarbon Engineering (L&T HE) manufacturing the structures in India.
Upon completion, the gas field is expected to significantly increase domestic production, helping meet India’s increasing energy demands while lowering reliance on imports. The project was delivered by a large, India-based project team, embracing the Indian government’s Make in India initiative.
“The opening of the U1-B (GX-06) well in the DWN-98/2 block is a major milestone that we can all be immensely proud of,” said Subramanian Sarma, Whole-time Director and Senior Executive Vice President (Energy), L&T, CEO and MD, L&T HE. “That we managed to achieve this despite extremely difficult project terrain and weather conditions even as a global pandemic raged on, speaks volumes of the resolve of the project teams. A testament to the combined synergies of all the consortium partners, this achievement will go a long way in ensuring project success and realizing ONGC’s vision of harnessing India’s rich energy reserves.”
The U-Field is now connected to ONGC’s Vashishtha subsea infrastructure, a project McDermott was recognized for in 2019 as EPC Contractor of the Year by the Federation of Indian Petroleum Industry.
McDermott’s vessels, including Derrick Barge 30, Derrick Lay Vessel 2000, the North Ocean 102 and Lay Vessel 105 (LV105) installed hundreds of miles of pipeline, 37 miles (60 kilometers) of umbilicals and nearly miles (16 kilometers) of flexible pipes.
