Tunnel Thruster

The tunnel thruster is installed in the bow or stern on the vessel
to create transverse thrust. Propellers that produce thrust could be driven by electric motor ，hydraulic motor or diesel engine. The driving part is assembled in the whole tunnel structure.

・ Possibility for flexible installation to reduce vibration.
・ CRP tunnel thruster making the size of the gear and the lower box significantly smaller, and the lower gearbox tends to streamline, reducing the flow resistance and noise.
・ The counter rotating propellers greatly reduces the bearing load and improves the safety and reliability of thruster operation.
Fixed pitch single propeller(FPP).
Fixed pitch counter rotating propellers(CRP).
Controllable pitch propellers(CPP).

Diesel engine drive, electric motor drive,hydraulic motor drive.

L-drive for vertical main drive motor installation(electric motor and hydraulic motor). Z-drive installation (often used for diesel engine drives but also electric drives). Flexible installation (to reduce vibration).

Typical applications for electric propulsion ship, hybrid ship, marine surveillance vessel, unmanned intelligent ship, ferry, tourist ship, deluxe passenger ship, container vessel, fishing vessel, LPG carrier, LNG carrier, PSV, AHTS, OSV, yacht, navy vessel and so on.
