Robbie Champagne Built the Boat His Industry Kept Putting Off
He started on deck, learned the work underwater, and spent decades earning the judgment to make one expensive decision: build a saturation vessel from the keel up. In 2026, that operator’s path opened into a larger offshore platform.
C-Dive Bet on a New Boat in an Oil Bust - and Turned an Aging Fleet Into Its Opening
In 2017, while offshore operators were stacking vessels, a three-man Houma diving outfit put a purpose-built saturation ship to work. The bet reveals when expensive, unfashionable infrastructure can become a small company's sharpest edge.
NOV
NOV built its name on the heavy machinery of drilling. Its more revealing product today is the connection between machines - a global web of parts, service, software and industrial know-how that keeps energy infrastructure moving.
BeeX
The Singapore deeptech cutting the tether on underwater inspection - autonomous drones that survey ships, wind farms and seabeds without divers, ROV pilots or a support vessel overhead.
Terradepth
Terradepth is an Austin-area ocean-data and subsea-intelligence company founded in 2018 by former U.S. Navy SEALs Joe Wolfel and Judson Kauffman. It pairs autonomous underwater vehicles that collect seabed data with Absolute Ocean, a cloud-native, government-grade platform for storing, visualizing, sharing and analyzing that data. Marketed as Ocean-Data-as-a-Service (ODaaS), Terradepth serves defense, offshore energy and maritime customers who need to map, understand and protect the roughly three-quarters of the planet that lies underwater.
Garth Sheldon-Coulson
Garth Sheldon-Coulson is the co-founder and CEO of Panthalassa, a Portland, Oregon company building free-floating, wave-powered nodes that generate clean electricity in the open ocean and pair it with onsite AI computing. A Harvard-trained lawyer with an MIT master's and a Bridgewater investing background, he pivoted from finance to spend nearly a decade inventing marine energy hardware. In May 2026 Panthalassa raised a $140M Series B led by Peter Thiel, pushing its valuation near $1 billion, on a bet that the open ocean is one of only three energy sources on Earth with tens of terawatts of untapped capacity.
