POWER & PROPULSION clutches and control systems. The company sells its prod- ucts to customers primarily in the pleasure craft, commer- cial and military marine markets, as well as in the energy and natural resources, government and industrial markets.

The company’s worldwide sales to both domestic and for- eign customers are transacted through a direct sales force and a distributor network.

The trend toward hybrid marine propulsion systems continues to accelerate, particularly in Europe, as suppliers and operators see increasing bene? ts: reduced emissions for regulatory compliance, and fuel and maintenance savings for faster return on investment. Clearly, Twin Disc sees sig- ni? cant opportunity in this trend. Its acquisition of Veth

Propulsion includes Veth’s industry-leading technology and an industry-wide reputation for innovation and reliability.

With expanded engineering capabilities, Twin Disc is ready to meet growing demand for electric or electric and diesel- electric propulsion systems. Its ? exible solutions include se- rial hybrid propulsion, or full electric, and parallel hybrid, toggling between electric and diesel power to turn the shaft.

Projects are already in the works in North America, Europe,

Asia and Australia, with more on the horizon—shaping the

Twin Disc hybrid propulsion systems combine electric motors and diesel engines, enabling switching between the two or using both for a power boost. Electric operation, practical at low power and speed, cuts fuel use and emis- 1,400-mile voyage from Washington State to Glacier Bay, sions. Hybrid uses include vessels with long waits between

Torqeedo and Poseidon collaborated this year to develop low full-power requirements let them rely on less costly a new commercial-grade electric azimuth thruster meeting diesel plus power boosts. the clean air requirements for European inland waterways.

The ? rst project is an ES-TRIN certi? ed solar-electric pas- senger ferry built by Ampereship in Germany.
