What was the ‘catastrophic implosion’ of the Titan submersible? An expert explains
The four-day-long search for the missing Titan submersible has come to a tragic end. Reports have confirmed the vessel was subject to a “catastrophic implosion” at some point during its voyage towards the Titanic shipwreck, which would have killed all five passengers instantly.
A debris field comprising “five different major pieces of debris” of various sections of the submersible was found on the sea floor by a remotely operated vehicle, about 500 metres away from the bow of the Titanic, officials said.
These findings are in line with previous news that an acoustic signature “consistent with an implosion” was detected by the US Navy on the same day the Titan began its descent.
The navy’s seabed sensors detected the signature in the general area the vessel was diving when it lost communication with its mothership. At the time the signature was considered “not definitive”.
We can assume the implosion actually happened on the first day of the dive – but perhaps not exactly at the same time communication was lost with the mothership. But why did it happen?
Most, if not all, submersibles and submarines operating at depth have a pressure vessel made of a single metallic material with high yield strength. This is typically steel for relatively shallow depths (roughly less than 300m), or titanium for deeper depths.
