Bow Thruster · Bow/Stern Thrusters
Crew and engineers aboard vessels rely on reliable tunnel thrusters to maintain precise control during maneuvering operations, ensuring safety and efficiency in tight spaces or challenging conditions. Side-Power/Sleipner’s SE/SP Series (Tunnel Thruster) offers a robust solution with capacities ranging from 5 to 200 kN thrust, suitable for various vessel sizes and applications. This series includes electric and hydraulic drive options, with models such as the SE30, SE60, SE80, SE100, SE130, SE170, and SP200, covering a power range from 3 to 200 kW. The thrusters feature a compact design, available in composite or steel tunnels, and are equipped with fixed-pitch propellers. Introduced in 1985, the SE/SP Series (Tunnel Thruster) has been trusted for its durability and performance. Common issues include DC motor brush wear, gear oil overheating from extended use, propeller hub corrosion due to dissimilar metals, and control relay failure. To ensure optimal operation, it is recommended to inspect the DC motor brushes every 500 hours and change the gear oil every 1,000 hours. The duty cycle for smaller models typically allows for 4 minutes of continuous use followed by a 15-minute rest period, as these thrusters are not designed for continuous operation. Spare parts for the SE/SP Series (Tunnel Thruster) are readily available from Side-Power/Sleipner in Fredrikstad, Norway, with a lead time of 1 to 3 weeks. The company’s wide dealer network ensures global support and service availability.
