Which company built the DSV Limiting Factor?

Triton Submarines built the DSV Limiting Factor.

The vehicle is also designated Triton 36000/2, referring to its full-ocean-depth design and two-person capacity. Triton Submarines developed it for explorer Victor Vescovo, whose company Caladan Oceanic commissioned the vehicle for the Five Deeps Expedition. It was designed to withstand the immense pressure found at depths approaching 11,000 metres.

Limiting Factor uses a titanium spherical pressure hull for the pilot and observer, acrylic viewports, syntactic-foam buoyancy, electric thrusters, and a manipulator arm. It was commercially certified by DNV for repeated full-ocean-depth dives, a demanding standard that distinguishes it from many research submersibles rated for shallower operations.

OceanGate was a separate company and did not build Limiting Factor. Kongsberg Maritime supplied or operated important mapping equipment on the expedition, including multibeam sonar, but it was not the submersible’s builder. Woods Hole Oceanographic Institution operates and maintains DSV Alvin, another famous vehicle, but it likewise had no role as Limiting Factor’s manufacturer.
