It says the company responsible for organizing the trip, OceanGate, mishandled the vessel’s construction and its preparation leading up to the accident.
As for the Fisheries Department, the report says it sent a letter to OceanGate CEO Stockton Rush in May 2021, saying the department planned to work with the company to assess the potential of its submersibles for scientific research.
According to the report, the letter goes on say the department could contribute funds for future missions, but the coast guard’s investigation found no evidence of any further collaboration or funding.
