Kongsberg’s Electric Towing Winch: A Game-Changer for Harbor Tugs

Efficiency Meets Sustainability in Maritime Tech

The tugboat industry is getting a high-voltage upgrade. Kongsberg Maritime has unveiled a new electric towing winch designed to revolutionize harbor operations, combining cutting-edge efficiency with a significantly reduced environmental footprint. Unlike traditional hydraulic systems, this winch leverages a frequency converter-driven motor, slashing power consumption while delivering up to 35 tons of pulling force—enough to handle even the most demanding port maneuvers.

“This isn’t just about replacing hydraulics; it’s about rethinking tugboat operations from the ground up,” says a Kongsberg engineer. “The winch is a leap forward in both performance and sustainability.”

One of the standout features is its elimination of onboard hydraulic systems, which reduces oil-related risks and maintenance headaches. The winch’s design prioritizes durability, with induction-hardened gears, high-quality bearings, and a mechanical spooling device. But speed is just as critical as strength: the quick-release function operates in under 3 seconds, meeting strict IACS compliance standards—a must for emergency scenarios.

Smart Controls and Future-Proof Tech

Operators will appreciate the winch’s stepless speed control, enabled by frequency converter technology, which allows for precise adjustments during towing. The system offers flexibility with single, double, and split drum configurations, catering to diverse operational needs. A user-friendly interface provides real-time data on rope tension, length, and speed, with alerts for system anomalies—accessible both locally and from the bridge.

“Integrating winch controls with Aquapilot thruster levers was a game-changer,” notes a Kongsberg spokesperson. “Now, captains can manage thrust and towing simultaneously, boosting safety and efficiency.”

Kongsberg isn’t stopping there. The winch is built with future upgrades in mind, including remote diagnostics and ecosystem integration. Backed by the company’s global service network, it’s a long-term investment for tug operators navigating the shift toward greener, smarter ports. With harbor tugs accounting for a significant share of port emissions, this electric winch might just be the pull the industry needs.
