Experts have suggested four possible scenarios for what may have gone wrong for OceanGate’s Titan submersible to lose communication one hour and 45 minutes into its two-hour descent.

1) Blackout: Titan may have lost power and fallen to the seabed, or an inbuilt safety system could have helped it return to the surface, where it could be drifting.

2) Fire: An electrical short circuit could have caused a fire, creating toxic fumes and compromising the vehicle’s navigation and control systems.

3) Entangling: The sub could have become entangled in the Titanic wreck’s extensive debris field, which covers approximately 15 square kilometres.

4) Implosion: A defect in the composite hull could have caused an instantaneous implosion – killing all on board in less than 40 milliseconds.

Time is of the essence, with search and rescue teams needing to find and free the passengers before its four-day supply of oxygen runs out.
