Rolex/National Geographic Deep Sea Challenge

The Deep Sea Challenge project was movie director James Cameron’s (Avatar, Titanic) solo depth diving project, where he set the world record for depth diving in an electric submarine.

Tritium’s James Kennedy (pictured far left) contributed battery management expertise as a member of the Deep Sea Challenge team.

For this expedition, Cameron squeezed into a pilot sphere so small he could not extend his arms. He was the sole occupant in a complex, 7.3m craft made of highly-specialised glass foam. During the expedition Cameron filmed footage for a feature-length documentary and collected samples for historic scientific research of the deepest part of the ocean. State-of-the-art engineering expertise (including Tritium’s) guaranteed the expedition a success.
