L&T Hydrocarbon Engineering, a wholly owned subsidiary of Larsen & Toubro, unveiled high-tech spool base facilities at L&T’s fabrication facility at Kattupalli, in Chennai.
These facilities are being employed to execute a lump sum turn key (LSTK) contract that has been secured from ONGC for a subsea installation by a consortium of J. Ray Mc Dermott, Berlian McDermott and L&T Hydrocarbon Engineering in international competitive bidding.
The contract is part of ONGC’s integrated development of deep water Vashishta & S1 fields on India’s east coast.
It is their first project, involving three subsea wells in depths ranging from 400m to 700m involving a daisy chain field architecture with subsea tie back to onshore terminal at Odalaveru through a dual 14” pipeline.
“L&T, down the years, has been known to make things that make India proud and we are proud to be involved in this project that is being done for the first time in India,” said Subramanian Sarma, CEO and managing director, L&T Hydrocarbon Engineering. “It is also for the first time that such high-end technology required for deep water operations is being transferred and embedded in India through our consortium partners, McDermott.”
T K Sengupta, director – Offshore, ONGC said: “For our deep water campaign, this is a very significant step because we are going towards a gas-based economy for which it was very important to prepare ourselves to the future challenges. It is also commendable that Kattupalli has geared itself to adopt this new technology and I am delighted with the pace and progress already achieved.”
He expressed confidence in the ability of the consortium to deliver the project on schedule and start production by mid-2017 and achieve full capacity of 2 billion cubic meters of gas per annum by end 2017.
This approximate 91 km of pipeline laying from onshore terminal to offshore deep water field involves 55 km of shallow water lay and 36 km of deep water lay using the spool lay method.
