Over 100 issues were recorded on the vessel in the years leading up to the Titan’s implosion, investigators shared Monday, adding that the ship suffered 70 equipment issues in 2021 and 48 issues in 2022.

Tony Nissen, OceanGate’s former engineering director, testified that if he or other staffers would bring up the issues with CEO Stockton Rush, who was among those killed in the implosion, the chief would brush their concerns aside after heated arguments.

Nissen, who was fired in 2019 after refusing to sign off on an expedition, was one of 10 former OceanGate employees set to be interviewed in the hearing.

Veteran diver and submersible pilot David Lochridge, who was hired by OceanGate in 2016, said Tuesday that he repeatedly clashed with Rush over how the CEO liked to “do things on the cheap.”
