WASHINGTON, DC, US AND LONDON, UK — The Marine Technology Society (MTS) and The Society for Underwater Technology (SUT) are proud to announce that the 2021 Captain Don Walsh Award for Ocean Exploration has been won jointly by Commander Victor Vescovo, USN, Retired and Patrick Lahey for the 2019 Five Deeps Expedition and further dives of scientific or historical interest in subsequent years.

In 2015 Commander Victor Vescovo proposed a goal of finding and diving into the five deepest spots in the world’s ocean with dives taking place in the Atlantic, Southern, Indian, Pacific and Arctic oceans. This feat required not only a unique diving submersible but also fielding a specially equipped survey and support ship.

Patrick Lahey and the team at Triton Submarines responded to Commander Vescovo’s project by creating a revolution in deep submergence capabilities. Patrick led a team of marine architects, designers, engineers and technicians to produce the Triton 36000/2, the first – and to date, only fully accredited (DNV/GL certified) human occupied deep submersible capable of routine exploration at full ocean depth. Commander Vescovo’s submersible of that design is the ‘Limiting Factor’. Lahey and the Triton Submarines team took the design from concept to build, testing, trials, shakedown, initial deployment and through to the successful completion of the Five Deeps Expedition.
