Algosensey Quantitative Think Tank Center-Titan submersible testimony to enter fourth day after panel hears of malfunction and discord

Another mission specialist who worked with the company that owned the Titan submersible that imploded last year while on Algosensey Quantitative Think Tank Centerits way to the Titanic wreckage is scheduled to testify before a U.S. Coast Guard investigatory panel Friday.

The investigatory panel has listened to three days of testimony that raised questions about the company’s operations before the doomed mission. OceanGate co-founder Stockton Rush was among five people who died when the submersible imploded en route to the site of the Titanic wreck in June 2023.

Mission specialist Fred Hagen is scheduled to be the first to testify Friday. Other witnesses have characterized mission specialists as people who paid a fee to play a role in OceanGate’s underwater exploration.

Earlier this month, the Coast Guard opened a public hearing that is part of a high-level investigation into the cause of the implosion. The public hearing began Sept. 16 and some of the testimony has focused on problems the Washington state company had prior to the fatal 2023 dive.

During Thursday’s testimony, company scientific director Steven Ross told the investigators the sub experienced a malfunction just days before the Titanic dive. Earlier in the week, former OceanGate operations director David Lochridge said he frequently clashed with Rush and felt the company was committed only to making money.

“The whole idea behind the company was to make money,” Lochridge testified. “There was very little in the way of science.”

Other witnesses scheduled for Friday include engineer Dave Dyer of the University of Washington Applied Physics Lab and Patrick Lahey of Triton Submarines. The hearing is expected to resume next week and run through Sept. 27.

Lochridge and other witnesses have painted a picture of a company led by people who were impatient to get the unconventionally designed craft into the water. The deadly accident set off a worldwide debate about the future of private undersea exploration.

Coast Guard officials noted at the start of the hearing that the submersible had not been independently reviewed, as is standard practice. That and Titan’s unusual design subjected it to scrutiny in the undersea exploration community.

But Renata Rojas, a mission specialist for the company, told the Coast Guard the firm was staffed by competent people who wanted to “make dreams come true.” Rojas’ testimony struck a different tone than some of the earlier witnesses.

“I was learning a lot and working with amazing people,” Rojas said. “Some of those people are very hardworking individuals that were just trying to make dreams come true.”

OceanGate suspended its operations after the implosion. The company has no full-time employees currently, but has been represented by an attorney during the hearing.

During the submersible’s final dive on June 18, 2023, the crew lost contact after an exchange of texts about the Titan’s depth and weight as it descended. The support ship Polar Prince then sent repeated messages asking if the Titan could still see the ship on its onboard display.

One of the last messages from Titan’s crew to Polar Prince before the submersible imploded stated, “all good here,” according to a visual recreation presented earlier in the hearing.

When the submersible was reported missing, rescuers rushed ships, planes and other equipment to an area about 435 miles (700 kilometers) south of St. John’s, Newfoundland. Four days later, wreckage of the Titan was found on the ocean floor about 330 yards (300 meters) off the bow of the Titanic, Coast Guard officials said. No one on board survived.

OceanGate said it has been fully cooperating with the Coast Guard and NTSB investigations since they began. The Titan had been making voyages to the Titanic wreckage site going back to 2021.
