Triton submersibles offer their occupants the most immersive experience possible, in total comfort and ultimate luxury. Yet, behind the scenes, there is one factor that takes precedent over all others: safety.

Before the first sketch, safety is top of our agenda where it remains throughout the design, manufacture, commissioning and ongoing operation.

It is more than a checklist, and goes beyond our rigorous testing.

It is how we think, and how we work. Safety is Triton.

Triton has a perfect safety record.

How Safe are civilian submersibles?

Last year approximately one million passengers enjoyed dives aboard the world’s civilian submersible fleet. In the three-decade operating history of the industry, ABS and DNV-GL classed submersibles have retained a perfect safety record. Civilian submersibles are, statistically, the safest form of transportation in the world today.

Return to Surface

To ensure that it is always possible to perform a controlled ascent and safely return to the surface, Triton implement a number of back-up safety systems across all of our submersibles:

  • Manual overrides on all critical systems
  • Direct air injection to ballast tanks
  • Jettisonable battery pods, drop-weights, manipulators, and tooling.

Furthermore, the vehicle’s subsea location is continually tracked and monitored from its host vessel, and each sub contains life-support and emergency battery power for an extended 96 hours.

More about Design


Design Depth
Pressure Test Depth
Operating Depth

Triton tests every submersible to pressures of at least 1.2 times the vehicle’s operating depth. Every component is designed, analyzed and certified to withstand even greater pressures.

Scrutinized by ABS or DNV-GL surveyors, each Triton will undergo a vigorous program of over 1,000 tests and checks. Structural materials are independently tested in a laboratory. Comms and tracking, life support, high-pressure systems, maneuvering, towing and vehicle stability are all tested and demonstrated. Finally, a manned dive to maximum operating depth, with a functional demonstration of each and every system, is required before the vehicle is approved.

Third-Party Classification

Don’t just take our word for it. All Triton submersibles are constructed to the exacting requirements of the American Bureau of Shipping or DNV-GL for the classification and construction of manned submersibles. This means owners and insurers can be certain that all materials are properly certificated and independently checked for chemical composition and strength, all designs have been scrutinized and approved, all components are manufactured under watchful inspection and all systems are fully tested and witnessed prior to delivery of the submersible.

Cayman Registry

In addition to ABS or DNV-GL classification, Triton submersibles can be built in full compliance with the Cayman Islands Shipping Registry (CISR) guidelines for design, manufacture, operation and maintenance for manned submersibles.

CISR is the preferred flag state for megayachts and their guidelines do not allow a non-CISR compliant submersible to be operated from a CISR registered support vessel. In addition, CISR’s guidelines for submersible registration are among the strictest worldwide. Submersibles that comply with CISR guidelines are likely to comply with the requirements of almost any other flag state (several do not have submersible guidelines or requirements).
