Deepwater Drilling in India

ONGC has significantly reshaped its Samudra Manthan tender, creating new implications for Deepwater Drilling India and offshore drilling contractors. Through its latest corrigendum, the company has removed floater and semisubmersible categories from the project scope and narrowed the requirement to one or more 3000-metre water-depth DP drillships. The decision signals a stronger focus on specialized deepwater exploration assets.
The revised structure changes both technical and commercial dynamics within Deepwater Drilling India. ONGC has reduced the firm charter period from 48 months to 36 months while retaining a 12-month optional extension. Although mobilisation fee caps have been increased, contractors now face lower revenue visibility and greater pressure to optimise asset deployment and operating efficiency.
A key feature of the amendment is the phased mobilisation schedule. The first rig must be mobilised within 180 days of the Notice of Award, while subsequent rigs will follow a staggered deployment sequence linked to 2027 timelines. This approach provides ONGC with greater operational flexibility while ensuring access to critical deepwater drilling capacity.
The removal of provisions allowing rig-category substitution further clarifies the tender structure and reduces bidder uncertainty. According to Indian Petroplus analysis, ONGC s latest move reflects an effort to secure drillship capability without committing to a broader offshore fleet programme. As offshore exploration gains momentum, Deepwater Drilling India is expected to remain a strategic investment area for India s upstream sector.
