Power and precision from a new generation of Tunnel Thrusters
Performance and design flexibility, engineered for various marine applicationsTunnel Thruster type TTH
The TTH Tunnel Thruster represents the next generation of our proven tunnel thruster technology.

Backed by over 60 years of hydrodynamic expertise, the Harmonised (H) range is designed to deliver compact, flexible, and installation-friendly propulsion performance for vessels operating in complex environments — from offshore platforms to naval operations.
Available in two propeller diameters — 1650mm and 1850mm — with power up to 1250kW, the TTH is optimised for Dynamic Positioning (DP) and Auxiliary (Aux) propulsion applications.
