Bechtel has developed India’s first deepwater gas field in the Bay of Bengal.
The KG D6 Gas project, for Reliance Industries Limited, encompassed subsea equipment, pipelines, a riser platform, and an onshore terminal. Bechtel managed engineering, procurement, installation, and commissioning of the project, which had an initial capacity of 2.8 billion cubic feet of gas per day--significantly increasing India's production capacity.
The project comprised 22 subsea wells in water up to 3,937 feet (1,200 meters) deep, with the potential to expand to 50 wells. Most of the wells are 22 to 25 miles (35 to 40 kilometers) offshore. KG-D6 is Reliance’s first offshore gas field development and its first underwater discovery, as well as the largest such discovery in the world in 2002.
The project also included routing seven pipelines up the Nilarevu River, and construction of a large onshore gas terminal 18.6 miles (30 kilometers) south of Kakinada to receive the gas from the offshore system, dehydrate it, compress it, and feed it into an onshore pipeline that leads to Mumbai.
Project teams worked in Mumbai and Kakinada, India; Kuala Lumpur, Malaysia; Melbourne, Australia; Oslo, Norway; Delft, Netherlands; London; and Houston. Bechtel enlisted the help of a specialist subcontractor to provide expertise in deepwater pipelines and subsea equipment.
