Swarch's new generation of electric drive systems based on permanent magnet technology with permanent magnet engines and frequency converters as core components provides more advanced control. The control system is equivalent to the energy-saving and efficiency control center, and keeps the entire power supply system stable, independent of external conditions, such as waves, ship speed and so on.
This revolutionary solution ensures that ships are more efficient and less expensive to supply, as this solution eliminates the need for auxiliary generators to generate electricity and allows the main diesel engine to operate and generate electricity at different speeds. Overall, it allows ships with 4-stroke, especially 2-stroke engines to save significant operating costs and be more compliant with the more stringent environmental regulations of the future.
“Flying fuel prices, global overcapacity and increasingly meager profits are forcing shipbuilders to rethink traditional system configurations. This is a new market opportunity for advanced technologies that can revolutionize ship power generation and use energy in an environmentally friendly manner. Our drivetrain technology revolutionizes the new era of hybrid propulsion systems, and large commercial vessels using 2-stroke engines will be the main driver of this innovation. Our technology can save shipowners 50,000 Euros a month. Fuel costs, which means a 7% annual profit increase,†said Swatch CEO and CEO Jukka-Pekka M?kinen.
Permanent magnet generator technology has achieved significant results in many industries with unparalleled design flexibility and energy efficiency. With higher power density, permanent magnet machines are more compact, lighter and smaller. Their superior performance in a variety of harsh operating environments proves their reliability and robustness. Swarch permanent magnets with corrosion resistance and high temperature resistance provide excellent performance.
Equipping the shaft generator with a frequency converter ensures that the vessel can effectively control the speed and provide a stable power generation unit for the entire ship's power generation system. The frequency converter allows the vessel to choose the most efficient way to supply power, depending on the situation, whether it is a main diesel engine or an auxiliary generator.
Permanent magnets provide high efficiency over the entire operating range, dramatically reducing fuel consumption. Compared with induction motors, permanent magnet machines are 2-4% more efficient at full load and 10% higher at partial loads. Because of the loss of rotor current in permanent magnets compared to induction motors. No need for excitation and reduced winding losses, resulting in higher efficiency. A synchronous permanent magnet motor uses high magnetic flux density NdFeB magnets, which are ideal for variable speed generators over the full range of speeds. A magnetic field is generated by almost no current loss from the rotor.
After upgrading, Swatch's new generation drive system has been significantly reduced in size and weight. This provides greater flexibility in the limited space configuration of the vessel.
In the challenging marine and marine sector, Swatch has partnered with partners to provide a complete range of energy efficiency solutions for ship designers and shipbuilders. We can also provide design selection consultation and project general contracting services. We can not only provide integrated solutions for new vessels, but also provide upgrades for existing vessels.
