 ONGC Deepwater Rig Tender: Samudra Manthan shifts toward a drillship-focused strategy
The latest changes to the ONGC Deepwater Rig Tender under the Samudra Manthan mission indicate a significant shift in India’s offshore exploration strategy. ONGC has revised the tender structure by narrowing the scope to 3000-meter water-depth DP drillships, removing the earlier provisions for semisubmersibles and anchor-moored floaters. This move sharpens the focus on deepwater drilling capability while reducing the complexity of fleet deployment. The revised ONGC Deepwater Rig Tender reflects the company’s effort to align technical requirements with long-term offshore exploration goals.
Another important change is the reduction of the firm charter period from 48 months to 36 months, while retaining a 12-month optional extension. This adjustment provides ONGC with greater contractual flexibility but increases risk for contractors operating high-value offshore assets. Although mobilisation fee caps have been increased, drillship owners will still need to manage deployment and investment risks carefully. The revised framework strengthens the position of specialised drillship operators while reducing opportunities for mixed-fleet bidders.
The updated mobilisation schedule also suggests a more structured deployment approach. The first rig must mobilise within 180 days of award, while additional rigs follow a phased timeline linked to future operational requirements. This creates a deployment hierarchy rather than a simple procurement exercise.The evolving ONGC Deepwater Rig Tender demonstrates ONGC’s intention to secure advanced offshore drilling capability without committing to a broader fleet programme. Indian Petroplus believes the revised structure signals a more targeted deepwater exploration strategy. This Indian Petroplus analysis indicates that specialised drillship contractors are likely to benefit most as ONGC prioritises operational flexibility, technical efficiency, and long-term offshore resource development, ONGC, Deepwater Rig Tender, Samudra Manthan, Offshore Drilling, Drillship, Deepwater Exploration.
