Kongsberg Maritime has launched a new electric towing winch intended for use in the harbor tug market. The winch is powered by a frequency converter-driven electric motor and is designed to reduce onboard hydraulic systems and lower power consumption.
The electric towing winch provides a maximum pulling force of 35 tons and is available with various drum configurations, including single, double, and split drums. Kongsberg said the new winch incorporates frequency converter technology to allow stepless speed control during rope handling. Brake holding loads can be matched to selected towing ropes.
The system includes a mechanical spooling device for wire winch applications and features a quick-release function that activates in under three seconds, in compliance with IACS requirements, Kongsberg said. The driveline features an electric motor, induction-hardened gears, and high-specification bearings.
Kimmo Haula, vice president merchant, handling systems, Kongsberg Maritime, said, “We know that tug operators need to have round-the-clock availability for towing operations, so with our global support network and product centre expertise we can ensure that when our customers need support, they get it.
“The control system for the new winch will also enable future upgrades on remote service and connectivity to Kongsberg ecosystem. With its launch, tug operators can look forward to enhanced performance, reduced environmental impact, and lower operational costs.”
The winch includes local and bridge-mounted controls, with displays for line tension, length, speed, and system alarms. It is designed to integrate with the company’s Aquapilot thruster control system, enabling simultaneous control of thruster and winch functions from a single lever.
Kongsberg noted the product is supported through Kongsberg Maritime’s global service network and is designed with future serviceability and digital upgrades in mind.
