Do you know a good submarine maker?

Catherine Nixey

"Meet John Ramsay, chief designer for Triton and a man who makes Bond’s Q look like an amateur. He designs the executive toy du jour: a personal submarine."

Inside the daring mission to reach the bottom of all Earth’s oceans

Tom Ward

"To demonstrate the problem, Blades pulls out his phone and plays a recording. Heard loud and clear over the airwaves, instead of Vescovo’s messages, is the hunting sonar of a school of whales. The solution? Install a filtering circuit, or try again when the oceanic traffic has died down."


The ultra-rich dive into a new obsession

“It’s going to be a world- or certainly industry-changing vehicle,” Ramsay said. The $25m, two-man submarine will take six months to design and another two years to build by Triton Submarines. “Nobody has built a deep-going [personal] vehicle that has been used again and again, but that’s what we are trying to do.”

Deep Impact: engineering an expedition to the oceans’ deepest points

Jon Excell

"Despite the enormous pressures, space constraints within the pressure vessel, coupled with the challenges of passing electrical signals through a titanium hull, mean that many of the key components – including the submarine’s lithium polymer batteries – are actually stored outside and designed to operate at the ambient pressure. “Electronics where possible need to be pressure-tolerant, so they’re immersed in oil that’s compensated at water pressure,” explained Triton’s chief electrical engineer Tom Blades.."


The Making of the Deep Submergence Vehicle (DSV) Limiting Factor

Nick Verola

"We'd just produced the first submersible ever to dive to Challenger Deep and the come back still working.....  so all we had to do was charge the batteries and dive again the next day..... and we did that five times."

Thirty-six thousand feet under the sea

Ben Taub

"Vescovo flew to the Bahamas, and Lahey took him for a test dive in Triton’s flagship submersible, which has three seats and is rated to a depth of thirty-three hundred feet. The third seat was occupied by an eccentric British man in his thirties, named John Ramsay, who didn’t seem to enjoy the dive; he was preoccupied with what he didn’t like about the submersible—which he had designed."


How Deep? Real Deep: Triton Unveils A New Experimental Sub That Hints At The Future

Mike Espindle

"Triton Principal Design Engineer John Ramsay said: “When we started thinking about the design of the Triton Titanic Explorer, we knew the unique visual capability of being the deepest diving acrylic hulled sub would need to be countered by the darkness at depth. What’s the point of going down if you can’t see anything when you get there? So, we developed the Gull Wings to counter just that."
