Introduction to Tunnel Thrusters
Tunnel thrusters are essential marine propulsion devices that are installed in tunnels running transversely through the hull of a vessel. They provide lateral thrust, enabling ships to maneuver more easily in confined spaces such as ports, canals, and during berthing and un – berthing operations. By generating thrust perpendicular to the ship’s longitudinal axis, tunnel thrusters enhance a vessel’s controllability, safety, and efficiency. Tunnel Thruster
