New Delhi, India – November 18, 2025 – In a significant move for the offshore drilling sector, the Competition Commission of India (CCI) has granted its official approval for the proposed merger between ADES International Cayman and Shelf Drilling, Ltd. The decision, announced today, paves the way for a strategic consolidation that will see Shelf Drilling become a wholly-owned subsidiary of ADES International Holding Ltd.
The Approved Combination Structure
According to the official release from the Press Information Bureau (PIB), the approved combination entails a specific structure:
- Surviving Entity: Shelf Drilling, Ltd. will be the surviving corporate entity post-merger.
- Settlement for Shareholders: The merger consideration for Shelf Drilling’s shareholders will be settled entirely in cash.
- New Ownership Structure: Following the merger, Shelf Drilling will operate as a wholly-owned subsidiary of its former rival, ADES International Holding Ltd.
Understanding the Key Players
The merger brings together two established entities in the oil and gas drilling services landscape.
- The ADES Group: ADES International Holding Ltd. acts as the holding company for a group of subsidiaries specializing in oil and gas drilling. The group has a notable presence in India, providing services through its fleet of three offshore jackup rigs. ADES International Cayman, the entity merging into Shelf Drilling, is a newly formed subsidiary with no prior business activities, created specifically for this transaction.
- The Shelf Drilling Group: Comprising Shelf Drilling, Ltd. and its downstream affiliates, the Shelf Group is actively engaged in operating and chartering drilling rigs, along with providing oilfield services for offshore exploration and development in India.
Implications and Market Context
The CCI’s approval is a critical regulatory hurdle cleared for this transaction. By combining their assets and operational expertise, the merged entity is poised to create a stronger, more competitive force in the offshore drilling market, particularly within the Indian region. This consolidation could lead to enhanced operational efficiencies and a more robust service offering for oil and gas exploration companies operating offshore India.
The CCI’s detailed order, which will provide deeper insights into the Commission’s analysis and any potential conditions for the approval, is expected to be published in the coming days.
