Electric or
hydraulic driven
Tunnel thrusters positioned at the bow or stern of a vessel can increase maneuverability and support dynamic positioning operations. We can supply electric or hydraulic motor-driven tunnel thrusters from 35kW to 300kW in single-propeller configurations and 45kW to 400kW in counter-rotating configurations. Counter Rotating tunnel thrusters can be chosen for vessels with limited draught or low-noise requirements. Depending on the vessel hull material, the tunnel structures can be manufactured in steel, aluminum, or GRP.
Control by systems
A full plug and play system is incomplete without a main control panel with joystick. Our touchscreen control panels are built for durability and are easy to use. Several options are available, varying from simple budget solutions to integrated custom solutions. Interface for full integration with dynamic positioning systems is available. Features are user-friendly, joystick for stepless control, compact and high-quality panels.
