OceanGate

On the morning of June 18, 2023, a 21‑foot experimental submersible called Titan slipped beneath the surface of the North Atlantic, aiming for the wreck of the RMS Titanic more than 12,000 feet down. ^[1] On board were five men: OceanGate CEO Stockton Rush, British businessman and adventurer Hamish Harding, Pakistani‑British executive Shahzada Dawood and his 19‑year‑old son Suleman, and famed French Titanic expert Paul‑Henri Nargeolet. ^[2]

Hours later, contact with Titan was lost. An international search and rescue operation fanned out over the open ocean. ^[1] Four days after the disappearance, debris was discovered on the seabed about 500 meters from the Titanic’s bow, revealing that Titan had suffered a catastrophic implosion that killed everyone on board. ^[1]

The implosion ended not only five lives, but also the story of OceanGate, the private company that had staked its future on selling high‑priced access to one of the world’s most famous shipwrecks. ^[1]

A Vision to Open the Deep

Stockton Rush did not come to deep‑sea exploration as a hobbyist tinkerer. He held a bachelor’s degree in aerospace engineering from Princeton University and an MBA from UC Berkeley’s Haas School of Business. ^[2][3] By 2009, he had founded OceanGate, where he oversaw both the company’s financial and engineering strategies. ^[2]

That same year, Rush and business partner Guillermo Söhnlein launched OceanGate in Seattle, with the stated goal of providing crewed submersibles for tourism, research, industry, and exploration. ^[1] Söhnlein left the company in 2013, just as OceanGate began designing its own submersibles. ^[1]

Building a Fleet on the Edge of Innovation

By 2013, OceanGate was no longer content to refurbish other people’s hardware. That year, the company began designing its own submersible, Cyclops (later called Cyclops 1), in collaboration with the University of Washington and Boeing. ^[1] OceanGate acquired a 12‑year‑old steel vessel named Lula from a company in the Azores and used its cylindrical hull as the basis for the new craft. ^[1][3]

Cyclops was unveiled in 2015. ^[1] It was a five‑person, steel‑hulled sub capable of diving to 500 meters, about 6.7 meters long, 2.7 meters wide, and weighing roughly 9,100 kilograms. ^[1] It was steered by a modified wireless game controller and had a battery life of up to eight hours. ^[1]

That same year, OceanGate moved its headquarters from Seattle to office and warehouse space at the Port of Everett’s Waterfront Center, planning to build a “fleet of manned next‑generation submersibles” and conduct sea trials from the waterfront. ^[1][5] OceanGate signed a five‑year lease for 3,600 square feet in the port’s Waterfront Center. ^[6]

Cyclops 1 quickly found work. In June 2016, it was used to survey the wreck of the SS Andrea Doria off the U.S. East Coast. ^[1][7] The company developed a towable launch and recovery platform—Ms. Lars—that could be flooded to sink below the roughest surface water and then raised again, allowing submersibles like Cyclops 1 to be launched and retrieved using ordinary ships instead of specialized vessels. ^[1][7]

But OceanGate’s real moonshot was a deeper‑diving successor: Cyclops 2. Designed as a five‑person submersible capable of reaching nearly 10,000 feet, it was being built in collaboration with the University of Washington’s Applied Physics Lab and Boeing’s research arm. ^[3] The hull would depart from industry norms: instead of heavy steel, it would rely on thick layers of carbon‑fiber reinforced plastic. ^[3]

Using carbon fiber at such depths was unusual. Traditionally, deep‑sea pressure vessels are made of steel or other metals to withstand the immense forces of the deep ocean. ^[3] Rush argued that lighter composite materials would cut bulk and cost while still providing strength, allowing a faster sub and a larger viewing window. ^[3]

In late 2016, OceanGate ordered the first titanium components for Cyclops 2 and contracted Spencer Composites in January 2017 to design and build the cylindrical carbon‑fiber hull. ^[1] The company projected that Cyclops 2 would cost between $10 million and $20 million to produce, funded by OceanGate and a group of undisclosed investors, while the associated University of Washington lab work carried a $5 million grant. ^[3]

In March 2018, Cyclops 2 received a new name: Titan. ^[1]

Selling a Ticket to the Titanic

Red Flags in the Design

Beneath the marketing, Titan was an experiment in pushing the boundaries of private engineering in one of the harshest environments on Earth.

OceanGate said Titan’s pressure hull combined a carbon‑fiber cylinder approximately five inches thick with titanium end caps about 3.25 inches thick. ^[5] It promoted Titan as the only crewed submersible built from a carbon‑fiber and titanium composite rather than the all‑metal pressure vessels typical of the industry. ^[1][5]

Between 2018 and 2019, OceanGate reported testing Titan to its maximum intended depth of 4,000 meters—roughly 13,100 feet. ^[1]

Later reporting, however, highlighted serious concerns from some engineers and former employees about Titan’s design and testing.

One striking claim involved the sub’s viewport. The window was reportedly rated to withstand pressure only to 650 meters, far shallower than Titan’s intended operating depth. ^[1] An engineer who worked on the viewport prepared an analysis concluding the design could fail after only a few dives to 4,000 meters. ^[1]

Other disputed accounts, summarized in subsequent reporting, claimed the original hull developed cracks after around 50 dives, that a new hull was built in 2021, and that parts from the earlier submersible were salvaged for reuse as additional lifting points against engineers’ advice. ^[1] These accounts have not been fully reconciled, but they became part of the broader public debate over how aggressively OceanGate pushed past conventional safety margins. ^[1]

Former OceanGate employee David Lochridge, for example, was reportedly fired after insisting Titan required more unmanned testing before carrying commercial passengers. ^[8] According to reporting on a subsequent lawsuit, he later emailed expedition organizer Rob McCallum warning that Rush could get himself and others killed to satisfy his “ego,” calling Titan “an accident waiting to happen” and saying no amount of money would convince him to dive in it. ^[8]

There were operational worries as well. Loss of contact with Titan had occurred multiple times on earlier test and tour dives, and sources later stated OceanGate did not immediately alert authorities when contact was lost on June 18, in part because such blackouts had happened before. ^[1]

The company’s choice of materials attracted scrutiny from outside experts. Using carbon fiber for a deep‑sea pressure hull was described as uncommon; traditionally, such vessels rely on steel specifically to withstand the overwhelming pressure. ^[3] The combination of a new material in this role, disputed engineering warnings, and a commercial schedule carrying high‑paying passengers formed a volatile mix.

Partners, Denials, and a Question of Who Built Titan

The Final Descent

By June 2023, Titan had already carried paying customers to the Titanic site. ^[1] For that season, seats were again priced at $250,000, a ticket marketed as both an extreme adventure and a contribution to science. ^[2]

On June 17, British businessman Hamish Harding wrote on Facebook that he was “proud” to be joining the latest expedition, calling attention to the presence of “legendary explorers” on the mission, including Paul‑Henri Nargeolet, who had made dozens of previous Titanic dives. ^[2]

The following day, Titan set out toward the wreck. ^[1] Somewhere on its way down, communications ceased. ^[1]

Because previous dives had also experienced communications problems, OceanGate did not immediately alert authorities, according to later reports. ^[1] But once the vessel was declared missing, an international search and rescue operation mobilized, with ships and aircraft sweeping the surface while sonar and remotely operated vehicles searched the depths. ^[1]

For days, the story gripped the world: a tiny private sub, a high‑stakes adventure, and a dwindling clock based on Titan’s estimated 96 hours of life support.

Debris on the Seafloor and a Confirmed Implosion

On June 22, 2023, a remotely operated vehicle located debris from Titan on the seabed about 500 meters in front of the Titanic’s bow. ^[1] The pattern of wreckage revealed that the submersible had imploded catastrophically, killing all five occupants. ^[1] The U.S. Coast Guard confirmed that the vessel had suffered a “catastrophic implosion” near the Titanic site. ^[4][5]

The Five Lives Lost

Behind the engineering debates and legal questions were five men who had trusted Titan with their lives.

Stockton Rush, OceanGate’s CEO and Titan’s pilot, had founded the company in 2009 and led both its business strategy and its engineering ambitions. ^[2][4] He had built his career at the intersection of aerospace and entrepreneurship, moving from aerospace engineering at Princeton to an MBA and then into roles in remote‑control technology and venture capital before turning to private submersibles. ^[3] Locally, he was also treasurer of the nonprofit OceanGate Foundation, where his wife Wendy Rush served as director and president, and the foundation worked in schools to encourage students toward STEM careers. ^[1][9] Educators who knew him described him as an explorer who pushed the envelope to reach the Titanic. ^[9]

Hamish Harding was a British businessman and chairman of Action Aviation, which sells aircraft to Fortune 100 companies, international corporations, heads of state, and high‑profile clients. ^[2] The British press had referred to him as a billionaire, though Forbes noted he did not appear on its list of the world’s richest people. ^[2] Harding held multiple Guinness World Records, including the fastest circumnavigation of Earth via both geographic poles in just over 46 hours in 2019. ^[2] He had flown to the edge of space on a Blue Origin mission and traveled more than two and a half miles down into the Mariana Trench with explorer Victor Vescovo. ^[2]

Shahzada Dawood, 48, was vice chairman of Dawood Hercules, an investment and holding company based in Karachi and part of a family business stretching back more than a century. ^[2] He lived in the United Kingdom with his wife and two children, Suleman and Alina. ^[2] Dawood held a master’s degree in global textile marketing from Philadelphia University and a law degree from the University of Buckingham. ^[2]

His son Suleman Dawood, identified as 19 years old, was described by family and corporate statements as a science‑fiction fan who enjoyed solving Rubik’s Cubes and playing volleyball. ^[2] Father and son boarded Titan together. ^[2]

Paul‑Henri Nargeolet was a French deep‑sea explorer renowned as one of the world’s leading Titanic experts. ^[2][8] OceanGate described him as “Titanic’s Greatest Explorer.” ^[2] He had led six expeditions to the wreck site and served as director of underwater research for RMS Titanic Inc., the company that holds salvage rights to the wreck and operates exhibitions of recovered artifacts. ^[2] Colleagues who worked with him for decades called him an “all‑around good guy.” ^[2]

These five men came from very different worlds—corporate aviation, Pakistani industry, French deep‑sea exploration—but shared a willingness to wager on a new kind of access to the deep. ^[2]

Everett Shuts Its Doors

As the world processed the news of Titan’s implosion, the physical home of OceanGate in Everett, Washington, went quiet.

On June 21, 2023—the same day the Coast Guard confirmed the submersible had imploded—the Port of Everett said OceanGate’s office on Craftsman Way had closed and would remain closed indefinitely. ^[1][4] Neighbors at the waterfront center described a somber mood and a small, unmarked bay that had suddenly become a magnet for national media. ^[9]

What Remains After the Implosion

The Titan disaster thrust deep‑sea tourism, private exploration, and experimental engineering into a harsh spotlight. The company that had once boasted of building the “safest vehicles on the planet” was gone; the submersible that promised ordinary people a window on the Titanic lay in pieces near the famous wreck. ^[1][7]

Unresolved questions linger over the technical decisions behind Titan’s design, the extent and meaning of its claimed partnerships with major institutions, and whether warnings from engineers and employees were adequately heeded. ^[1][5][8] Legal and regulatory assessments will continue to sift through liability waivers, marketing claims, and safety practices to determine where responsibility lies. ^[1][5]

What is certain is that five men died chasing a frontier—and that the line between bold innovation and unacceptable risk, in the deep ocean as on land, is being redrawn in the cold wake of their loss.
