Verbal communication of the key items I have addressed in my attached document have been dismissed on several occasions, so I feel now I must make this report so there is an official record in place.\u201d<\/p>\n The report detailed \u201cnumerous issues that posed serious safety concerns,\u201d according to the filing. These included Lochridge\u2019s worry that \u201cvisible flaws\u201d in the carbon fiber supplied to OceanGate raised the risk of small flaws expanding into larger tears during \u201cpressure cycling.\u201d These are the huge pressure changes that the submersible would experience as it made its way and from the deep ocean floor. He noted that a previously tested scale model of the hull had \u201cprevalent flaws.\u201d<\/p>\n Carbon fiber composites can be stronger and lighter than steel, making a submersible naturally buoyant. But they can also be prone to sudden failure under stress. The hull that Lochridge was writing about was made by Spencer Composites, the only company to have previously made a carbon fiber hull for a manned submersible. (That submersible was commissioned by explorer Steve Fossett for a record-breaking dive, but he died in a light aircraft crash before it could be used.)<\/p>\n Lochridge\u2019s recommendation was that non-destructive testing of the Titan\u2019s hull was necessary to ensure a \u201csolid and safe product.\u201d The filing states that Lochridge was told that such testing was impossible, and that OceanGate would instead rely on its much touted acoustic monitoring system.<\/p>\n The company claims this technology, developed in-house, uses acoustic sensors to listen for the tell-tale sounds of carbon fibers in the hull deteriorating<\/span><\/a> to provide \u201cearly warning detection for the pilot with enough time to arrest the descent and safely return to surface.\u201d<\/span><\/p>\n Lochridge, however, worried in the lawsuit that the system would not reveal flaws until the vessel was descending, and then might only provide \u201cmilliseconds\u201d of warning before a catastrophic implosion.<\/p>\n Russell McDuff, a veteran oceanographer and chairman of OceanGate\u2019s scientific and research foundation for three years, noted that contact with the Titan was lost on Sunday after only an hour and 45 minutes. \u201cThis suggests to me that they might have still been in the water column, descending to the Titanic,\u201d told TechCrunch in a phone interview.<\/p>\n Lochridge also strongly encouraged OceanGate to have a classification agency, such as the American Bureau of Shipping, inspect and certify the Titan.<\/p>\n A day after filing his report, Lochridge was summoned to a meeting with Rush and company\u2019s human resources, engineering and operations directors. There, the filing states, he was also informed that the manufacturer of the Titan\u2019s forward viewport would only certify it to a depth of 1,300 meters due to OceanGate\u2019s experimental design. The filing states that OceanGate refused to pay for the manufacturer to build a viewport that would meet the Titan\u2019s intended depth of 4,000 meters. The Titanic lies about 3,800 meters below the surface.<\/p>\n The filing also claims that hazardous flammable materials were being used within the submersible.<\/p>\n At the end of the meeting, after saying that he would not authorize any manned tests of Titan without a scan of the hull, Lochridge was fired and escorted from the building.<\/p>\n Lochridge, who claimed he was discharged in retaliation for being a whistleblower, made his filing after OceanGate sued him in federal court in Seattle that June. OceanGate has accused him of sharing confidential information with two individuals, as well as with the Occupational Safety and Health Administration (OSHA). In the lawsuit, OceanGate characterized Lochridge\u2019s report as false, and\u00a0 accused him of committing fraud<\/span><\/a> by manufacturing a reason to be fired.<\/span><\/p>\n The lawsuit was settled in November 2018. Neither OceanGate nor Lochridge responded to requests for comment. OSHA could not immediately provide details of the alleged report. A routine OSHA inspection of OceanGate in 2021 found only three minor workplace safety violations<\/span><\/a> resulting in no financial penalties.<\/span><\/p>\n A few months after Lochridge\u2019s dismissal, the company published a blog post<\/span><\/a> that laid out its reasons for not having Titan certified by the American Bureau of Shipping or a similar organization.<\/span><\/p>\n \u201cThe vast majority of marine (and aviation) accidents are a result of operator error, not mechanical failure,\u201d it reads. \u201cAs a result, simply focusing on classing the vessel does not address the operational risks. Maintaining high-level operational safety requires constant, committed effort and a focused corporate culture \u2013 two things that OceanGate takes very seriously and that are not assessed during classification.\u201d<\/span><\/p>\n In 2019, Rush gave an interview to Smithsonian <\/span><\/a>magazine, in which he said: \u201cThere hasn\u2019t been an injury in the commercial sub industry in over 35 years. It\u2019s obscenely safe, because they have all these regulations. But it also hasn\u2019t innovated or grown\u2014because they have all these regulations.\u201d<\/span><\/p>\n Following Lochridge\u2019s departure, the Titan was tested safely on increasingly deep dives, including to 4,000 meters in the Bahamas<\/span><\/a>. However, it seems one of Lochridge\u2019s concerns would soon be borne out. In January 2020, Rush gave an interview to GeekWire in which he admitted that the Titan\u2019s hull \u201c<\/span>showed signs of cyclic fatigue<\/span><\/a>.\u201d Because of this, the hull\u2019s depth rating had been reduced to 3,000 meters. \u201cNot enough to get to the Titanic,\u201d Rush said.<\/span><\/p>\n During 2020 and 2021, the Titan\u2019s hull was either repaired or rebuilt by two Washington state companies, Electroimpact and Janicki Industries, that largely work in aerospace. In late 2021, the Titan made its first trip down<\/span><\/a> to the wreck of the Titanic.<\/span><\/p>\n Spencer Composites says that the Titan was not using its carbon fiber hull on Sunday\u2019s dive. Presumably apart from the hull work, one source familiar with the company told TechCrunch that not much with Titan had changed at all since 2018.<\/p>\n At the time of publication, the Titan remains missing, with Rush, French diver Paul-Henri Nargeolet, British billionaire Hamish Harding, Pakistani businessman Shahzada Dawood and his son reportedly on board. A massive search and rescue operation is underway.<\/p>\n \u201cThey\u2019re doing everything that they logically can,\u201d McDuff said. \u201cBut I\u2019m a little pessimistic because of the amount of time that\u2019s gone by.\u201d<\/p>\n<\/p><\/div>\n <\/br><\/br><\/br><\/p>\n
