Larsen & Toubro on 6 April 2005 stated that it received an order valued at Rs.1,864 crore from Oil & Natural Gas Corporation for a major overhauling project at ONGC's biggest asset,  Mumbai High.

The order will be executed by L&T in consortium with US-based Global Industries Offshore. L&T's share in the contract is Rs.930 crore.

The project involves replacing old submarine pipeline and laying new ones, modification of oil well and process platforms in the western offshore production areas of ONGC, including Bombay High and Heera fields. The entire work has to be completed in three years. About 45 per cent of the work is to be completed by April 2006.

These pipelines and platforms were originally installed by ONGC over the last 30 years and the project is designed to extend the life and reliability of the facilities. ONGC is expected to award another three offshore contracts this year, it is learnt.
