Siemens: Improved propulsion with energy-efficient and environmentally friendly heat recovery system

The WHRS is a waste heat recovery system for vessels that helps reduce energy costs by up to 12%. The waste heat recovery system utilizes the heat from exhaust gases to generate steam and produce additional electrical power. Intelligent energy management ensures the optimal overall performance and safe, reliable operation at all times. A waste-heat recovery system not only cuts the energy costs, it also reduces the CO2 and NOx emissions of the vessel.

The WHRS waste heat recovery system gives several crucial competitive advantages
– Smaller main engines and fuel tanks = more useable 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
