Engineering and safety experts to be questioned by Coast Guard panel for Titan disaster hearing

NORTH CHARLESTON, S.C. (WCBD) – A former crew member on a Titan dive recalled how unnerving the experience was during the Coast Guard’s public hearing into why the Titan imploded on its way to view the shipwrecked Titanic.
Karl Stanley, who runs his own expedition business where he takes passengers on dives, said that OceanGate, the company that ran the Titan, nearly killed him because they took him on a test dive in the Bahamas.
Former OceanGate administration chief Amber Bay said the company took safety concerns seriously and disputed previous claims of tolerance for willful violations.
On Wednesday, the investigative panel will hear three witnesses, including a safety and engineering expert. First up is Don Kramer, the acting chief of the National Transportation Safety Board Materials Lab, followed by William Kohnen with Hydrospace Group Inc.
Closing the day will be Bart Kemper with Kemper Engineering.
LIVE UPDATES:
12:36 p.m.
Hearing adjourned until 1:40 p.m.
12:33 p.m.
OceanGate had a second window made by a different company for the Titan after the first one was damaged.
The second window was made by Heinz Fritz GmbH.
Hydrospace currently has 16 subs.
12:25 p.m.
The first window made by Hydrospace in 2018 was damaged in 2019, according to Kohnen
12:21 p.m.
The acrylic window is typically tested in 1,000 to-depth cycles. Kemper Engineering tested the first window made by Hydrospace.
12:19 p.m.
Hydrospace made a non-standard acrylic window which they gave to OceanGate and an inspection report, according to Kohnen. Although the window was not PVHO-certified, they used PVHO-certified material to build it.
12:14 p.m.
Kohnen reached out to Rush in an attempt to offer window testing analysis and giving an overview report.
12:12 p.m.
Kohnen said he made it clear to Rush that OceanGate needed to test the window, but they did not perform the testing with Hydrospace.
12:10 p.m.
Hydrospace first had contact with OceanGate in 2007 or 2008 because the company had a submersible for use that OceanGate was interested in, according to Kohnen.
12:09 p.m.
Kohnen mostly communicated with OceanGate CEO Stockton Rush and former Engineering Director Tony Nissen.
12:00 p.m.
Hydrospace made the window for the Titan submersible.

Kohnen said pilots and crew had to go through extensive training for first HydroSpace submersible dive.
11:23 a.m.
Hydrospace built its first submersible in 1995.
11:03 a.m.
Kohnen details his professional background. Kohnen is the co-founder of Hydrospace Inc, executive director of the World Submarine Organization and member of special review committee for American Bureau of Shipping.
