Ron Allum, whose submersible the Deepsea Challenger carried Titanic director James Cameron to the bottom of the ocean in 2012, has some thoughts about the missing Titan.
Implosions, fishing net entanglements and electrical system faults are some of the many things that can go wrong when sending a submersible to the bottom of the ocean, Sydney engineer and deep-sea explorer Ron Allum says.
“[Cameron] proved that building a submersible was within the realms of a fairly rich, wealthy person and that a number of these people are very passionate about the environment and they like to think of themselves as adventurers,” Allum said. “I think very rarely would it be a catastrophic failure. There was a US remotely operated vehicle that suffered a series of implosions when doing a deep dive in the Pacific Ocean.
“Submersibles usually carry equipments like sonar, forward-looking sonar or depth sounder-based instruments and these often are outside of the pressure hole in their own pressure vessels,” he said. “If you turn off your lights at the bottom of the ocean, it is pitch black ... you couldn’t even see your hand in front of your face.”
