Larsen & Toubro Hydrocarbon has secured an offshore contract valued at Rs 781 crore from Oil and Natural Gas Corporation (ONGC).

The contract, won against international competitive bidding, encompasses total ‘EPCI’ — Engineering Procurement Construction & Installation — of three wellhead platforms, spread over Heera and South Heera fields of the state—run exploration giant, a company statement said today.

The project, part of ONGC’s strategy to re—develop Heera and South Heera fields off Mumbai coast to meet India’s rising energy demands, is scheduled to be completed by April 2014.

These un—manned wellhead platforms will be connected with the nearby Heera process complex by subsea cables for remote operation.
