L&T Energy Hydrocarbon Offshore (LTEH Offshore) has won a major offshore contract from the Oil & Natural Gas Corporation (ONGC) for the Additional Development of Ratna–I (ADR I) and NLM-14 project on India’s west coast.

Under the project, LTEH Offshore will undertake engineering, procurement, construction, installation and commissioning (EPCIC) activities covering three new well-head platforms and one riser platform. The scope also includes several sections of subsea pipelines and cables, along with brownfield modifications to existing offshore facilities.

The development is intended to increase production and contribute to the continued expansion of ONGC’s offshore assets in the region.

LTEH Offshore delivers integrated EPCIC services to the offshore oil and gas sector, backed by in-house engineering expertise, advanced fabrication facilities and a dedicated marine vessel fleet. Its capabilities span both shallow-water and deep-water developments across international markets.

With more than four decades of offshore project experience, the company has delivered projects covering fixed platforms, subsea pipelines and structures, brownfield modifications and decommissioning.

Commenting on the order win, Parthasarathi Chatterjee, Senior Vice President & Head – L&T Energy Hydrocarbon Offshore, said: “The ADR-I and NLM-14 developments are significant additions to India's offshore energy infrastructure and demonstrate the continued investment in enhancing production from established offshore assets.

Drawing on our extensive offshore EPCIC experience, we look forward to delivering these developments safely and efficiently, while supporting ONGC’s long-term production objectives.”
