India's state-owned Oil & Natural Gas Corporation (ONGC) is advancing development projects at key west coast offshore fields to boost domestic oil and gas production and enhance energy security. The company is focusing on redeveloping maturing assets and expanding production potential, which includes replacing subsea pipelines and executing new offshore projects.

Current Bidding Process for Key Projects

At least three contractors—India’s Larsen & Toubro, the UAE’s NMDC Energy, and Indonesia’s Meindo Elang Indah—have submitted bids for the fast-track additional development of two shallow-water projects: the Ratna & R-Series (ADR-I) and the NLM-14 oil and gas projects. ONGC is currently evaluating these offers and is expected to award the contracts within the next two to three months, with no anticipated delays.

Scope of the ADR-1 and NLM-14 Projects

The workscope for the ADR-1 project involves installing new infrastructure, including two new wellhead platforms (R-12-6A and VGN-A) and one riser platform (RJP). It also includes a new bridge connecting the RJP to the existing R-10-A wellhead platform, along with 56 kilometres of well fluid pipelines and 22 kilometres of subsea cables.

The NLM-14 project encompasses the engineering, procurement, construction, installation, and commissioning (EPCIC) of a new wellhead platform (NLM-14), about 12 kilometres of well fluid pipelines, close to six kilometres of gas lift pipelines, and associated topsides modifications. Both the Ratna and NLM assets are already producing, and these expansions are specifically aimed at increasing output, though the targeted incremental production volumes have not been confirmed.

Project Timeline and Strategic Importance

Following contract awards, the two EPCIC projects are expected to be completed in approximately 23 months. ONGC's west coast assets are crucial to its long-term strategy, with the operator planning significant investment in multiple upcoming projects in the region to maximize output from maturing fields.

Broader West Coast Development Plans

These projects are part of a larger portfolio. In 2022, ONGC unveiled plans for 18 offshore EPCI projects worth billions of dollars, involving a mix of brownfield and greenfield developments. Other key projects on the west coast include the North Tapti fields, PRP-8, the Cluster 9 development, the B-193 phase two project, platform makeover projects, and the MB0SN-2005/1 development.
