Titan Submersible

Titan was a five-person deep-sea submersible operated by OceanGate for research and tourism, including dives to the wreck of the RMS Titanic.

Titan was a five-person deep-sea submersible operated by OceanGate for research and tourism, including dives to the wreck of the RMS Titanic. It became internationally known after it imploded during a 2023 dive in the North Atlantic, killing all five people aboard.

Design and purpose

Titan was a privately operated submersible built for deep-sea tourism, survey work, research, and inspection. It was previously known as Cyclops 2 and used a titanium and carbon-fibre composite hull. The vessel had a claimed maximum depth rating of 4,000 metres (13,123 feet).

2023 Titanic expedition

In June 2023, Titan lost contact during a dive to the Titanic wreck site in the North Atlantic. Search operations later found debris field evidence indicating the submersible had imploded. All five people aboard were later confirmed dead.

Investigation and findings

U.S. authorities later determined that the vessel suffered a catastrophic implosion. A 2025 U.S. Coast Guard Marine Board of Investigation concluded that OceanGate’s inadequate design, certification, maintenance, and inspection processes were primary contributing factors.

Public impact

The incident prompted widespread scrutiny of deep-sea tourism, submersible safety, and regulation of novel vessel designs. Titan became one of the most widely discussed maritime disasters of the 2020s. The Titan disaster received extensive coverage in Canadian media and was of interest in Canada because the submersible vanished near the Titanic wreck in the North Atlantic, a route and search area closely followed by Canadian readers.
