Adani Ports and Special Economic Zone (APSEZ) announced a significant investment of ₹13,000 crore (approximately $1.6 billion USD) to expand its subsea operations in Europe, in collaboration with the US-based engineering firm Oceaneering International. This initiative aims to build a 200-vessel global marine fleet and is part of APSEZ's strategy to establish one of the world's largest integrated marine platforms, focusing on offshore logistics, underwater engineering, and deepwater infrastructure services. As part of this expansion, Astro Offshore, a Dubai-based subsidiary, has acquired the Astro Atlas, a 97-metre DP2 multipurpose support vessel capable of operating in ultra-deepwater environments. This vessel will facilitate subsea construction, cable laying, and pipeline installation in water depths exceeding 3,000 metres. APSEZ is targeting marine revenue of ₹6,000 crore (around $720 million USD) by FY31 from its offshore business portfolio, emphasizing the importance of subsea operations for offshore energy and marine infrastructure projects.
