Leighton India secures ONGC shallow water projectProjects and Operations // December 8, 2010
Leighton India has been awarded a US$17 million contract for work on the G1-GS15 Shallow Water Project, an offshore field development by the Oil and Natural Gas Corporation (ONGC).
Located at Krishna-Godavari Basin, 20km off Amalapuram coast in the Andhra Pradesh state of India, the G-1 field’s water depth is approximately 250-450m.
The field operates through a sub-sea production system consisting of sub-sea production wells and production manifold. The wells are connected by dual sub-sea pipelines rising to the processing facilities on-shore.
GS15 is a shallow water field lying 6km offshore which includes two platforms GS15-4 (existing) and GS15-1 (new) and is integrated in the overall field development project.
Leighton’s scope includes:
• Installation of Wye piece and 10-inch piggable full bore subsea valve.
• Installation of topside extensions on GS15-4 topside (existing).
• Install and tie in riser on GS15-4 and GS15-1 topsides.
• Hook-up and pre-commissioning of topsides.
• De-watering, pigging, hydro testing and onshore tie-in of subsea pipelines.
• Testing of umbilical.
• Post trenching and backfilling in near shore area.
Russell Waugh, Leighton India Managing Director, said: “ONGC holds the largest share of hydrocarbon acreages in India and contributes the majority of India’s oil and gas production. The G1-GS15 work marks the second existing project Leighton is undertaking for ONGC, alongside the US$750 million Pipeline Replacement Project 2 currently being delivered in the Mumbai High Fields. The project builds on our oil and gas portfolio in the region and further strengthens our partnership with ONGC.”
