GET IT RIGHT WITH TWIN DISC HYBRID AND ELECTRIC SYSTEM SOLUTIONS TO ACHIEVE YOUR GOALS

MOVE FORWARD WITH TWIN DISC As leaders in power transmission technology, Twin Disc delivers the solutions that best fit your specific application: diesel power, full electric, or a hybrid system that takes advantage of both. EVOLVING OPTIONS, GROWING BENEFITS Hybrid and electric systems give you a better way to: • Be environmentally friendly • Meet emissions standards as well as stakeholder expectations • Save on fuel and maintenance costs • Reduce noise and vibration • Increase efficiency Here’s how we define the options: Full electric systems eliminate the main diesel engine and its maintenance...

CATAMARAN FERRIES Fleet: Maid of the Mist (passenger catamarans) Location: Niagara Falls, New York The Veth L-drives enable the ferries to move upriver without diesel fumes, view-obstructing exhaust stacks, or noise to compete with the falls. “And everyone is impressed by the lack of vibration—even the Coast Guard,” says Christopher M. Glynn, president, Maid of the Mist Corp. Shipyard: Burger Boat Company, Manitowoc, Wisconsin Designer: Propulsion Data Services Integrator: ABB Propulsion: Two Veth VL-200 L-drives per vessel Situation Two Maid of the Mist ferries give about 1.6 million tourists...

HINCKLEY PICNIC BOAT SIGNATURE EDITION YACHT Model: Picnic Boat 40 S Builder: Hinckley Yachts The hybrid upgrade enables Hinckley’s iconic Picnic Boat to run in near silence. The vessel glides silently away from the dock and can travel farther than with an electric-only platform. With SilentJet engaged, the Picnic Boat 40 S’s cruising speed is seven knots. Range is at least an hour (at seven knots, and up to 90 minutes at 5.5 knots), and the Picnic Boat 40 S cruises at 35 knots (depending on load) under diesel power. Location: Portsmouth, Rhode Island Propulsion: Hinckley SilentJet™ technology,...

This parallel hybrid system uses standard Twin Disc propulsion control. It's best suited for vessels with long waits between jobs, high percentage of slow speed operation, and operating in restricted areas and zero emission zones. Twin Disc technology enables implementation into any standard QuickShift® marine transmission. 1. System Overview • Parallel hybrid using diesel and electric power • During low-power operation, the e-motor uses excess diesel power to generate electricity • In high-demand phases, electric power can boost diesel power 2. Marine Transmission • Based on standard marine...

SMOOTHER, EMISSION-FREE SAILING. Three Veth VL-700 L-drives (533 kW) provide the primary propulsion for the Oranje Nassau VI, incorporated in a revolutionary hull design that lets the tanker move smoothly through shallow waters. A battery charged by the ship’s engines can power the L-drives’ electric motors when required, enabling the vessel to sail through harbors emission-free. Veth Propulsion by Twin Disc provided an additional three L-drives for the Oranje Nassau V.

This parallel hybrid system delivers the optimal balance between electric and hydraulic power requirements. 1. System Overview • Parallel hybrid using diesel and electric power • In high-demand phases, electric power and diesel power can assist one another • The e-motor can use excess diesel power to generate electricity • Power regeneration is possible through braking (inertia or vehicle) 2. RePTO Drive with MasterClutch™ • Installed between diesel engine and E-Motor/generator providing mechanical interface to direct-mount E-Motor/generator • Single and dual tower options available for driving...

NEXT-GENERATION HYBRID LOG STACKERS Product: AM 370 Pump Drive Maximum input power: 700 kW (939 hp) 0.7:1 ratio @ 1200 rpm “We’re operating the diesel engine at 1200 RPM, which significantly reduces noise,” says Kjell Arne Engberg, EdiLog CEO. “The AM 370 at an 0.7:1 ratio gives us the hydraulic flow and generator efficiency we need.” Application: Pulp mill log stacker Manufacturer: EdiLog Electrical system design: Elforest Technologies Location: Östrand, Sweden Situation Log stackers must run all day, every day to maintain pulp mill production— but continuous diesel engine use drives up carbon...

This serial hybrid system uses an electric motor and can both generate power and store energy. The system optimizes fuel consumption with a generator. It's best suited for vessels operating in restricted areas and zero emission zones. 1. System Overview • Serial hybrid using electric power • Optimizes fuel use via gensets operating at the top of their fuel efficiency range. When propellers operate at low power, some gensets can be switched off, and the rest continue in their optimal range • Machinery compartments can be located to optimize cargo space or meet class requirements 2. Azimuth Thruster...

REVOLUTIONARY RIVERBOAT SETS SAIL IN THE U.S. The American Song is equipped with advanced technology including twin ultralow-sulfur Caterpillar diesel engines that reduce emissions and fuel use. Two Z-drives from Veth Propulsion by Twin Disc (Model VZ-1250A-CR) deliver maximum maneuverability through full 360-degree thrust vectoring. VT-400 Tunnel Thrusters aid navigation without generating distracting noise. The result is superior, reliable, nimble propulsion for faster, more comfortable sailing.
