For two decades, Adani Ports’ (APSEZ) business began where ships docked. Now, one of its newest vessels seems to be in no hurry to reach port.

Unlike conventional merchant ships that go from port to port, Energy Savanah, soon to be renamedAdani PortsAPSEZ’s marine arm, Astro Offshore in contract with Oceaneering International Inc., for European Subsea Expansion Astro Atlas, loops, lingers, and returns. 

Follow the vessel’s routes long enough, and a pattern emerges.

The roughly 100-meter deepwater workhorse spends much of its sweet time around the North Sea in northwestern Europe and the Turkey-Eastern Mediterranean. One is the world’s busiest offshore energy basin, and the other is among the most geopolitically contested subsea corridors.

This is because the world’s newest energy infrastructure is increasingly moving offshore. LNG terminals now float at sea. Wind farms are spreading across European waters. Gas fields are moving farther from the coast. Even the cables carrying electricity and internet traffic increasingly lieThe KenMeta to get the world’s longest internet cable to India. It’s 100% exposed on the seabed.

The oceans are becoming too deep to ignore. An ouroboros of the modern economy, if you will: AI wants power. Power wants gas. Gas wants oceans. Oceans need ships.

India depends on much of this infrastructure but owns barely any of it. And Adani seems to want to change that. 

The conglomerate has been wiring itself into that loop: buildingBusiness StandardAdani, Jabil to partner for AI data centre hardware manufacturing venture electricity-hungry data centres, owning the offshore infrastructure to procure the energy, and getting the renewables to keep the engines humming.
