Sub-Atlantic's range of hydraulic thrusters have become the preferred propulsion for ROVs and cable burial/maintenance vehicles. Working in a highly aggressive environment, they have earned a reputation for reliability, efficiency and exceptional performance.
Sub-Atlantic hydraulic thrusters are reliable due to a rugged, lightweight contruction and a ceramic shaft sealing system. These thrusters also benefit from producing near equal forward/reverse efficiency within a 5% band. The data from our performance testing has been witnessed by DNV to ensure your system design performs exactly as expected. These thrusters also benefit from the ability to fit any motor displacement size to any of the four thruster sizes due to the common, one-size motor/thruster interface. This is advantageous when accuratly matching to vehicle hydraulic system parameters.

Sub-Atlantic’s new direct drive range of brushless DC thrusters break new ground in thrust, low weight and enhanced reliability. They are currently available in four sizes, each incorporating Sub-Atlantic’s unique StatorshieldTM technology.
Sub-Atlantic’s unique StatorshieldTM system allows the thruster to continue running in the event of a shaft seal failure and subsequent flooding, without damage to the winding or electronic components. Integral electronic drives are oil filled and pressure compensated to 3000 metres / 10,000 feet. Four sizes are available with propeller diameters up to 380 mm / 15” and bollard thrusts up to 220 kgf / 485 lbf.
