This study outlines the physical mechanisms involved in a submersible implosion and analyzes the loss of the Titan submersible (‘sub’) that occurred on 18 June 2023 during a mission to visit the wreck of the Titanic. Titan’s collapse mechanisms at the moment of implosion are described in detail and outer hull fracturing rate, subsequent implosion rate, accompanying heat release and other key processes are quantified. Plausible causes of the hull’s leak leading up to critical loss of the sub's hermetic closure are reviewed using test results made publicly available by the U.S. Marine Board of Investigation.

Key Points

Hull Weaknesses

The carbon fibre hull had manufacturing defects, including voids, porosity, and inadequate adhesive bonding, leading to significant delamination.

Sensor Data

Real-time monitoring recorded acoustic and strain anomalies before the fatal dive, indicating escalating structural fatigue.

Implosion Process

A small leak compromised the sub’s airtightness, leading to a rapid inward buckling and the collapse of the hull at extreme depths.

Thermodynamic Effects

The implosion generated a secondary steam-driven explosion, dispersing the hull and debris.

Engineering Lessons

The incident highlights the need for improved materials, bonding techniques, quality control, and monitoring to prevent similar failures in future submersibles.
