Underwater Harvester represents the first true arrival of viable marine technology in underwater forests. Developed and manufactured by Triton, it is the world's only deep-water logging machine, combining proven elements from timber-harvesting and submarine vehicle technology on an innovative platform.
Deepwater Access The Sawfish™ not only navigates precisely by a remote pilot, it can operate to any depth. Alternative systems (grapples or divers) are limited to approximately 25 m, even though 80 percent of submerged timber resources are found at greater depths.
Economical and Efficient While alternative systems use the same mechanism to cut and retrieve trees, The Sawfish™ achieves significant efficiencies by de-coupling the cutting and surfacing processes, enabling it to perform multiple cuts without returning to the surface. And with no new roads to build and no fires or pests to control, Triton’s system becomes even more economical.
Safety Triton’s harvesting operation does not involve falling trees or working with heavy machinery in tight spaces or sloped terrain. And by removing hazardous trees from reservoirs, Triton creates safer environments for recreational and commercial use.
7000 lbs on land and slightly buoyant in water
Fully remote with 8 video cameras and sonar
Powered by a 75 HP electric motor, using biodegradable and vegetable oil-based hydraulic fluids
Feller grapple and 55-inch chainsaw
Handles larger trees than any land-based mechanical harvester due to water buoyancy
50 inflatable/reusable airbags to float trees to surface (one bag per tree)
