Structure of the submarine that disappeared while carrying passengers to see the wreck of the Titanic

The Titan, which carried five people who went missing while visiting the Titanic wreck, was controlled by a PlayStation controller and had a window for passengers to look out.

Authorities are searching for the 22-foot-long (6.7 m) titanium and carbon fiber boat OceanGate Titan, which disappeared on June 18 during a dive tour of the Titanic wreck. The coast guard estimates the ship has enough oxygen for passengers to breathe for about 70 hours. The Titan went missing off the coast of North America in the Atlantic Ocean, carrying a crew and four passengers. Both the Boston and Canadian coast guards are searching for the missing boat, operated by tour company OceanGate Expeditions.

Dimensions of the Titan submersible

The ship measures 670 cm x 280 cm x 250 cm and can dive to a depth of 4,000 m. The Titan weighs 10,432 kg and can travel at a maximum speed of 5,556 km/h thanks to its Four Innerspace 1002 electric propulsion system. The vehicle is equipped with a Rayfin 4k Sub C Imaging camera, a Teledyne 2D sonar, a 40,000 lumen headlight and a 2G Robotics laser scanner. The electronics and propulsion control compartment are located outside the pressure hull to increase the space for the crew and equipment in the compartment. The Titan also has a toilet located right next to the window.

Control

The Titan is controlled by a reinforced PlayStation controller, though it lacks a GPS system. The ship is guided by text messages from the surface team. The Titan communicates with the tracking team via USBL messages. A large digital screen streams live images from multiple external 4K cameras and also acts as a door to the rear equipment compartment.

Launching and recovery platform

The Titan is launched from a platform equipped with multiple ballast tanks to help it descend and rise, eliminating the need for large support vessels or coastal cranes. Once the ballast tanks are filled with water, the platform is lowered to a depth of 30 feet to avoid turbulence at the sea surface. Underwater, the platform uses a patented shock-absorbing buoyancy system to maintain stability. At the end of each dive, the Titan lands on the platform and the entire system is brought to the surface within two minutes after pumping air into the tanks.

Design and purpose

The Titan was designed and built with a carbon fiber hull and titanium dome. A team of engineers at NASA's Marshall Space Flight Center served as consultants to OceanGate during the development of the submersible. The company announced in late April that Titan was in the final stages of preparation for its 2023 Titanic expedition.

The bow hatch at the front of the vessel acts as a door and provides the largest view of any manned deep submersible. Titan has a real-time hull condition monitoring (RTM) system that analyzes the effects of pressure changes as the sub dives deeper and accurately assesses the structural integrity. The system provides early warning to give the pilot enough time to stop the dive and return to the surface safely.

Diving time

The dives can last 10 hours at a time, with participants spending a total of 10 days at sea on a larger vessel. In an interview last year, Stockton Rush, CEO of OceanGate, said their submersible can accommodate five people and can descend to the depths of the Titanic wreck.

In 2022, the Titan made 10 dives to the Titanic wreck in the space of a few weeks. The latest dive was not the ship's first this year. The Titan is the second model in the Cyclops-class submersibles that OceanGate has operated since 2015 in three oceans to depths of nearly 500 meters.
