James Cameron’s Deep Sea Challenger


In preparing for a record breaking dive to the bottom of the Mariana Trench, James Cameron approached Subsalve the help with 2 key problems. The first was to maintain safe positioning of the submersible during launch and retrieval operation and the second was to develop a back-up system to return to the surface should primary systems fail.


Subsalve provided standard products to aid in the launch and retrieval, and they developed together with the Challenger team a self contained emergency buoyancy system that included a custom pontoon and a specialized inflation source that was packaged in a confined space on the submersible.


On March 26th, 2012 the Deepsea Challenger, piloted by James Cameron, achieved touch down in the Mariana Trench at a depth of 35,736 feet and safely returned to the surface.
