After Titan sub’s loss, Coast Guard reviews regulations

The U.S. Coast Guard took a deep dive into the regulations governing submersibles today at a public hearing looking into the causes of last year’s loss of OceanGate’s Titan sub and its crew. And the issues raised sometimes got as murky as the depths of Puget Sound, where Titan underwent its first tests.

Among the witnesses who testified at the hearing in South Carolina was John Winters, the master marine inspector for Coast Guard Sector Puget Sound. For more than a decade, Winters worked with OceanGate CEO Stockton Rush on the regulatory requirements for two of the Everett, Wash.-based company’s subs, known as the Antipodes and Cyclops 1. But today he told the Coast Guard’s Marine Board of Investigation that he had nothing to do with Titan.

Winters recalled a time, about two years ago, when he was at OceanGate’s headquarters on the Everett Marina to check on one of the two submersibles in the Coast Guard’s records. He said he saw the three subs on a barge, and someone told him, “We finally got our submarine to go to the Titanic.”

“But that was the only thing in passing,” Winters said. “Nothing about what it was constructed to, who witnessed it. None of that stuff. Just, ‘Here it is, look at the outside.’ … That’s as far as it went.”

In the wake of the Titan tragedy, the Coast Guard is likely to go further. One of the objectives of this month’s hearings is to lay the groundwork for regulatory changes that would help head off future fatal incidents involving submersibles.
