Larsen & Toubro’s energy hydrocarbon offshore business has secured a large order from state-run Oil and Natural Gas Corporation for additional development projects off India’s west coast, the company announced on Wednesday.
The order has been awarded to L&T Energy Hydrocarbon Offshore for the Additional Development of Ratna-I and NLM-14 projects. L&T classifies a large order as one valued between Rs 2,500 crore and Rs 5,000 crore. The company did not disclose the exact value of the contract.
The scope includes engineering, procurement, construction, installation and commissioning of new offshore infrastructure. According to L&T, the work will involve three new well-head platforms, one riser platform, multiple segments of subsea pipelines and cables, and brownfield modifications to existing offshore installations.
The projects are intended to enhance production and support the continued development of ONGC’s offshore assets in the region, L&T said in a statement. The contract therefore combines construction of new facilities with changes to installations that are already operating, requiring integration between new development infrastructure and existing offshore assets.
“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,” Parthasarathi Chatterjee, senior vice president and head of L&T Energy Hydrocarbon Offshore, said.
Chatterjee said the projects would combine new offshore facilities with modifications to existing operating fields. The work will require engineering coordination and execution across both brownfield and new development infrastructure, he added.
L&T Energy Hydrocarbon Offshore provides integrated engineering, procurement, construction, installation and commissioning services for the offshore oil and gas industry. The business has previously executed projects involving fixed platforms, subsea pipelines and structures, brownfield upgrades and decommissioning assignments, according to the company. L&T said the business has operated across these areas for four decades.
The order comes as ONGC continues to invest in the development and enhancement of production from its offshore fields. The state-run producer is seeking to sustain output from existing assets while expanding infrastructure in India’s western offshore basin, L&T said.
L&T shares were trading at Rs 3,997.25 on the BSE at about 10:10 a.m. on Wednesday, up Rs 37.25, or 0.94 per cent, according to the report. The company did not provide a project completion schedule or disclose further details on the contract’s execution timeline in the announcement.
The next stages will involve engineering, procurement, construction, installation and commissioning work for the Ratna-I and NLM-14 developments, alongside the planned modifications to existing offshore facilities.
