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.

Starfish Space will inspect dead satellites for NASA

Tukwila, Wash.-based Starfish Space has won a three-year, $15 million contract from NASA for a mission aimed at doing up-close inspections of defunct satellites in orbit.

Such inspections, to be carried out using Starfish’s Otter spacecraft starting in 2027, could blaze a trail for even more ambitious missions involving the repair or removal of such satellites.

The mission is known as SSPICY, an acronym that stands for Small Spacecraft Propulsion and Inspection Capability. NASA awarded the Phase III Small Business Innovation Research contract after a study that provided Starfish and three other small businesses with funds to develop mission concepts. (The other three companies were Kayhan SpaceTurion Space and Vast Space.)

Taking care of orbital debris is a key component of NASA’s Space Sustainability Strategy. Orbital debris mitigation and satellite servicing are also key parts of the business model for Starfish, a five-year-old startup that was founded by two veterans of Jeff Bezos’ Blue Origin space venture, Trevor Bennett and Austin Link.

“We are excited to expand our partnership with NASA, building on our shared commitment to advancing in-space manufacturing and assembly capabilities,” Bennett said today in a news release. “It’s an honor for Starfish to lead the first commercial debris inspection mission funded by NASA. We look forward to collaborating on this and future satellite servicing missions to enable a new paradigm for humanity in space.”

Investigators identify problems with Titan sub’s hull

pair of reports by the National Transportation Safety Board found evidence of imperfections in the carbon-fiber hull that was made for OceanGate’s Titan submersible — plus indications that the hull behaved differently after a loud bang was heard at the end of a dive in mid-2022.

At the time, OceanGate team determined that the loud bang was not a serious problem, but less than a year afterward, the sub and its crew were lost in a catastrophic implosion during a trip to the wreck of the Titanic in the North Atlantic,

Donald Kramer, an senior materials engineer who presented NTSB’s findings today at a Coast Guard hearing in South Carolina, declined to go beyond the data and speculate on whether the imperfections or the bang figured in Titan’s doom. But one leading theory for the sub’s failure suggests that weaknesses in the hull gave way under the extreme pressure of the deep ocean.

Radian Aerospace tests prototype for space plane

Seattle-based Radian Aerospace has finished the first round of ground taxi testing for a prototype aircraft that’s meant to blaze the trail for a first-of-its-kind, single-stage-to-orbit space plane.

Radian said the low-speed runway tests were successfully completed this month in Abu Dhabi, with the aim of assessing the subscale prototype’s flight characteristics in preparation for building its full-scale Radian One spaceship.

“These successful tests represent an early but significant step in our broader journey to bring Radian One to market,” Richard Humphrey, co-founder and CEO of Radian, said today in a news release. “While we know there is much work ahead, each step in our robust test program brings us closer to transforming access to space with rapid, reusable and cost-effective transport to low Earth orbit.”

Livingston Holder, Radian’s co-founder and chief technology officer, said the uncrewed PFV01 prototype is a one-12th-scale version of Radian One, measuring roughly 15 feet (4.9 meters) long. “It’s powered by two jet engines,” he told GeekWire. “So, it’s not a rocket-powered system, it’s a jet-engine system.”

During the taxi tests, the prototype performed a series of pitch-up maneuvers and short hops, reaching speeds of around 50 knots (57.5 mph). “We have a lot of data that’s come down, and so we really want to understand what that looks like before we move to the longer runway and start pushing higher speeds,” Holder said.

Submarine builder tells how a trip in Titan unnerved him

Karl Stanley has done more than 2,000 dives in submersibles that he’s built himself, so he was intrigued when OceanGate CEO Stockton Rush invited him down to the Bahamas for a test dive in the company’s Titan sub in 2019. But by the end of that dive, Stanley’s curiosity turned to concern.

“In retrospect, there were a lot of red flags,” Stanley said today during a Coast Guard hearing into last year’s loss of the Titan sub and its crew during a trip to the wreck of the Titanic in the North Atlantic. Rush, who was the sub’s pilot, and four other people lost their lives in last year’s tragedy.

The Coast Guard Marine Board of Investigation, meeting in South Carolina, is looking into the causes of the tragedy and is expected to recommend measures to head off such tragedies in the future. Part of its job is to review OceanGate’s missteps during Titan’s development.

Back in 2019, Everett, Wash.-based OceanGate was testing the sub in the Bahamas, in anticipation of taking its first trips to the Titanic later that year. Rush had made a solo trip to more than 3,900 meters (12,800 feet) in depth the previous December, and Stanley was one of three people set to accompany him on a follow-up dive.

Stanley, who operates a submersible tour company in Honduras, had come to know Rush through the tight-knit community of sub operators. He recalled traveling to Everett to help out with the construction of Titan’s landing and recovery platform — and said he was “excited” about OceanGate’s plan to use a lightweight carbon-fiber hull for Titan.

For the test dive, Titan was brought about 10 miles offshore, and made a gradual descent into the depths. Stanley said he had been warned to “be prepared for noises” — but even with that warning, he wasn’t prepared for what he heard on the way down.

Engineer says safety was shortchanged on Titan sub

In the run-up to last year’s implosion of OceanGate’s Titan submersible, cost concerns played a role in decisions that may have contributed to the catastrophe, a former director of engineering for the Everett, Wash.-based company told investigators today at a Coast Guard hearing.

Phil Brooks, who headed up the engineering team starting in 2021, said OceanGate’s financial woes contributed to his decision to leave the company in early 2023, just months before the sub and its crew were lost during a dive to the wreck of the Titanic, 12,600 feet down in the North Atlantic.

“It was clear that the company was economically very stressed, and as a result, that they were making decisions and doing things … I felt that the safety was just being compromised way too much,” Brooks told the Coast Guard Marine Board of Investigation, which is due to wrap up a series of public hearings this week.

OceanGate client tells the tale of a Titanic tangle

OceanGate’s Titan submersible briefly became tangled up in the wreck of the Titanic during a 2022 dive, a mission specialist who was on the sub told investigators today.

“We had a skid stuck for a minute,” Fred Hagen said during a hearing in South Carolina that focused on the causes of last year’s loss of the sub and its crew. “It wasn’t a big deal.”

The Coast Guard’s Marine Investigation Board is reviewing the history of Everett, Wash.-based OceanGate’s Titan sub development effort, with the aim of making recommendations to avoid future undersea tragedies.

Last year’s catastrophic implosion killed five people: OceanGate CEO Stockton Rush, who served as the sub’s pilot; veteran Titanic explorer P.H. Nargeolet; British aviation executive and adventurer Hamish Harding; and Pakistani-born business executive Shahzada Dawood and his son, Suleman.

Hagen went on two Titan dives — one in July 2021, which was aborted when one of the sub’s thrusters malfunctioned, and the other in July 2022, which successfully reached the Titanic at a depth of 12,600 feet (3,840 meters).

Nargeolet steered the sub as the crew members took in the shipwreck’s iconic sights, including the bow of the 112-year-old wreck and the ruins of the Grand Staircase. But Hagen said he wanted to see more, and he persuaded Nargeolet to head back toward the stern section.

“I’d asked him to go around where the break was, and for a few moments we had gotten stuck,” he said. “He was very quiet, and he was working the controls. … I leaned over, and I said, ‘P.H., it seems that we’re stuck.’ And he says, ‘Yes, Fred, we are.’”

Hagen said that the skid was momentarily snagged in “pipes and things” on the Titanic wreck, but that Nargeolet managed to free up the sub after no more than a minute or two. The surface support team became concerned about what was happening and “told us to come up immediately,” Hagen said.

“Obviously, when you’re down there, it feels like a big deal. I think P.H. certainly wasn’t overly concerned,” he said.

Titanic traveler makes a tearful plea for citizen science

Amateur adventurer Renata Rojas took a trip to the Titanic in OceanGate’s Titan submersible in 2022, and she was aboard Titan’s support ship last year when the sub and its crew were lost. Now she’s worried that the regulatory response to the tragedy will close off opportunities she and other citizen explorers have enjoyed.

Rojas fought back tears as she shared her concern today at a Coast Guard hearing that was aimed at determining the cause of Titan’s loss and formulating recommendations to avoid future tragedies.

“What we’ve all gone through is still very raw. Nothing is going to bring our friends back,” she told the investigators on the panel.

“I hope that this investigation creates an understanding that with exploration, there’s risk. And without taking that risk and the exploration, the world would still be flat,” she said. “I hope that innovation continues so we can make the oceans accessible to people like me who got to fulfill a dream, and that you still allow citizen scientists to participate in expeditions.”

Video views show the shattered remains of Titan sub

Video views from the search for OceanGate’s Titan submersible show mangled components from the craft — and tell the tale of last year’s dramatic implosion, which led to the loss of the sub and its five-person crew.

The U.S. Coast Guard released two videos this week in support of technical testimony that’s expected to be given during this month’s hearings into the cause of the incident, taking place in North Charleston, S.C.

The hearings began Sept. 16 and will continue on Sept. 19 with testimony from Renata Rojas, who was a mission specialist on an earlier Titan dive to the wreck of the Titanic in the North Atlantic; and from Steven Ross, a marine biologist who served as OceanGate’s scientific adviser. Technical testimony is likely to come later.

Both videos were captured on June 22, 2023, by a camera mounted on a remotely operated vehicle that took part in the search for the sub. The ROV came upon the scene four days after Titan went missing, and provided the conclusive evidence confirming that the sub had come apart amid the deep ocean’s crushing pressure.

One video shows Titan’s aft titanium dome and ring, plus remnants of the hull and carbon-fiber debris. The forward titanium dome and its viewport can also be seen, not far away. The other video shows Titan’s tail cone, emblazoned with the OceanGate logo.

OceanGate whistleblower traces roots of tragedy

Whistleblower David Lochridge said today that his concerns about OceanGate and its approach to undersea exploration began long before the company built the submersible that imploded last year during a dive to the Titanic shipwreck.

Lochridge referred back to 2016, when OceanGate CEO Stockton Rush crashed a different submersible called Cyclops 1 into the wreck of the Andrea Doria while Lochridge watched.

“He basically drove it full speed into the port side of the bow, and we could hear the cracking of the fairing as he got us jammed in underneath,” Lochridge recalled. “I’m not going to say how foul my language was, but it wasn’t good.”

At the time, the Andrea Doria expedition was hailed as a momentous achievement for OceanGate. But for Lochridge, a veteran submersible pilot who had joined the company months earlier, it was the start of a sour relationship with Rush.

During the second day of Coast Guard hearings into last year’s loss of OceanGate’s Titan submersible and its five-person crew, Lochridge traced how he tried to sound the alarm about what he saw as lapses in Titan’s design and construction — and how he ran into resistance at the Everett, Wash.-based company.
