Two Fingers, One Chain Reaction: How Mumbai High Vanished

Two Fingers, One Chain Reaction: How Mumbai High Vanished

A cook aboard an ONGC support vessel severed the tips of two fingers, and within two hours India's largest oil platform collapsed into the sea, killing twenty-two people and leaving eleven never recovered. The routine decision to transfer that injured crewman by crane forced a support ship up against a windward platform leg during monsoon swells - so how did a small medical rescue become an irreversible chain reaction that swallowed a $370 million installation?

In this episode, we lay out the sequence of events that afternoon of July 27, 2005, describing the platforms, vessels, weather, and operational choices that led from a galley injury to catastrophe, and ask whether the available technical records and survivor testimony are enough to explain why no public investigation report was ever produced.
