OceanGate never requested the Coast Guard inspect the Titan submersible, according to John Winters, master marine inspector with the Coast Guard Sector Puget Sound.
Winters testified on Thursday before the Coast Guard Marine Board of Investigation as part of their inquiry into the doomed Titan submersible, which imploded last summer, killing all five people on board.
Winters also claimed Former OceanGate CEO Stockton Rush complained to him about Coast Guard regulations.
“He did express on multiple occasions that regulations were stifling his innovation process,” Winters testified. The inspector also said OceanGate “never attempted to circumvent any regulations,” despite Rush’s complaints.
Mark Negley, an engineer with Boeing, also testified on Thursday morning.
Negley said Boeing only worked with OceanGate during short periods. The company did a “brief” feasibility study from 2012 to 2013, he said, before doing two acoustic studies in 2016. Their last communication was in March 2020, Negley testified, when Boeing declined to respond to OceanGate’s request for a proposal.
Negley once sent Rush his safety analysis of Titan’s hull, WIRED reports, warning that there would be a “high risk of significant failure” if the contraption went to the depth of the Titanic wreckage.

‘Root cause’ of Titan sub implosion unknown, engineer says
The root cause of the implosion on the Titan sub is still unknown, according to Bart Kemper, principal engineer of Kemper Engineering.
”The root cause for the implosion is indeterminate,” Kemper testified on Wednesday. “At this time, there are multiple unmitigated single-point failures...which means that all it takes is that one thing for the whole thing to go.”
Thursday testimony schedule
Testimony will resume on Thursday as the Coast Guard Marine Board of Investigation continues its inquiry into the 2023 Titan sub implosion that killed all five people on board.
Thursday’s hearing will kick off with testimony from Justin Jackson, a materials engineer at NASA. Afterward, Mark Negley of Boeing will testify. Negley once sent Rush his safety analysis of Titan’s hull, WIRED reports.
Afterward, John Winters with the Coast Guard Sector Puget Sound will give his testimony. The day will end with Lieutenant Commander Jonathan Duffett of the Coast Guard Office of Commercial Vessel Compliance.
An engineer testified the Titan sub’s hull showed signs of ‘delamination.' What does that mean?
Much of the Titan sub’s hull showed signs of “delamination,” Dr. Don Kramer, an engineer with the National Transportation Safety Board, testified on Wednesday, citing wreckage from the 2023 implosion.
Delamination occurs when the layers of the hull begin to separate. Layers of carbon fiber were laminated, or bonded together, to create the sub’s hull.
Kramer’s testimony was accompnaied by haunting new photos of the Titan sub wreckage.
OceanGate CEO didn’t understand the word ‘no,’ engineer testified
William Kohnen, CEO of Hydrospace Group Inc. and chairman of the Manned Underwater Vehicles Committee said OceanGate CEO Stockton Rush was not open to criticism when he testified on Wednesday.
“I don’t think many people ever told Stockton, ‘no.’ Don’t think he understood that concept very much,” Kohnen said.
Rush’s long-time friend, Karl Stanley, also testified on Tuesday that the former OceanGate CEO seemed “scared” while on board his Titan sub in 2019.
Final witness of the day to testify
William Kohnen with Hydrospace Group Inc. has ended his testimony.
The final witness today is Bart Kemper, principal engineer of Kemper Engineering. His testimony is set to begin any moment.
ICYMI: OceanGate’s Titan submarine relied on ‘idiotic’ Excel spreadsheet
OceanGate used a hand-typed Excel spreadsheet to track its ill-fated Titan submersible, according to a former contractor for the firm.
A hearing into OceanGate’s Titan sub, which imploded during an expedition to the wreck of the Titanic last year, revealed that its navigation system allegedly relied on team members manually inputting the coordinate data into a spreadsheet in order to track the vessel.
The incident last July killed all five people on board, including OceanGate’s CEO and co-founder Stockton Rush.

Dr. Don Kramer, an engineer with the National Transportation Safety Board, testified earlier today that the Titan sub’s carbon fiber hull showed signs of flaws.
William Kohnen, chairman of the Manned Underwater Vehicles Committee, also noted that former OceanGate CEO Stockton Rush was not open to criticism.
“I don’t think many people ever told Stockton no,” Kohnen said. “Don’t think he understood that concept very much.”
“This is not something where we don’t want you to do it,” he added. “We want you to do it right.”
