Solutions and products for power generation and distribution

Power LV is an integrated, modular, and scalable system for providing a reliable and economical onboard power supply in low-voltage technology. It comprises brushless synchronous generators to support all extremes of power demand, switchgear specially developed for marine use, and a power management system. In addition, various transformers and frequency converters come online to support system demands. The vessel’s generator, switchgear, transformers, and converters for the low-voltage supply can be freely combined as required, with the energy management system ensuring optimized interactions.

Thanks to integrated protection mechanisms (for example, short-circuit protection, electromagnetic compatibility, shock resistance, and automatic blackout start-up function), the low-voltage system achieves outstanding reliability with optimal efficiency, while minimizing fuel consumption by the vessel’s generator.

Your advantages with Power LV

• Highly efficient low-voltage power generation and distribution
• Low fuel consumption
• Enhanced operating security and fail-safe performance, for example through automatic load sharing, synchronization, and distribution
• High availability and easy maintenance
• Increased competitiveness and investment protection

SISHIP Boost with WHRS is a waste-heat recovery system for vessels that helps reduce your energy costs by up to 12 percent. The waste-heat recovery system utilizes the heat from exhaust gases to generate steam and produce additional electrical power. It not only cuts your energy costs, but also reduces the CO₂ and NO_x emissions of your vessel. Additionally, you gain more flexibility in vessel design. Smaller fuel tanks permit a more creative use of space and line, and the ship’s main drive can get by with a lower-rated output. Dependable, internationally available, standard components and our well-established spare parts logistics facilitate maintenance and provide you with maximum reliability.

All the functionalities of the WHRS are controlled using an energy management system that ensures optimal use of the available energy and automatically adapts shaft generator operation to current requirements. That means you are able to access additional power reserves, reduce wear and tear on the main engine, and increase the reliability of the onboard power supply.

Your advantages with WHRS

• Smaller main engines and fuel tanks = more usable space
• Permanent reduction in fuel costs and emissions
• Significantly lower maintenance costs, thanks to less wear of the main drive
• Excess electrical power used to boost propulsion
• Complete solution for the onboard power supply
• Optimal use of available energy

The PEM fuel cell is ideally suited for use as an air-independent power supply for submarines. It enables dive times to be extended to weeks, if required, which significantly minimizes the risk of being detected. That’s because the PEM fuel cell modules use oxygen and hydrogen to produce electricity, so the potential dive time is restricted only by the supply of stored media and the boat’s energy demand. The system works without atmospheric air and is completely exhaust-free.

Another important advantage is that the PEM fuel cell has an ultimately low signature in operation: This helps reducing the aggregate acoustic signature of the submarine. The system’s noise signature lies well under all threshold values. With their electrochemical properties, the fuel cells themselves operate noiselessly. Even the ancillary units are optimized for low noise or can be easily incorporated into noise encapsulation thanks to their compact design.

Your advantages with PEM fuel cells

• Huge increase in dive times
• Silent energy conversion, low acoustic signature
• Minimized stray field, non-magnetic casing
• Increased efficiency and long service life
• Emission-free and environmentally friendly
