Simulation-based Diagnostic Concept for Waste Heat Recovery

Development System Diagnostics

Waste heat recovery is used increasingly on large vessels to maximise energy utilisation. Siemens has developed a diagnostic tool especially for modern waste heat recovery systems based not on a simple comparison of measured values but on using simulations to ascertain the desired state of system components. The software can be flexibly configured and targets faster fault detection and localisation.


The propulsion and on-board power installations of modern ships are becoming increasingly complex due to new systems which employ waste heat recovery (WHR) technology for reducing fuel consumption and for compliance with ever-stricter emissions limits. The elements of a typical system are shown schematically in Figure 1 while Figure 2 shows typical orders of heat loss from a ship’s main engine in the form of a Sankey diagramme. Figure 3 shows the potential benefits of WHR technology for a range of main engine sizes, including projected amortisation times.
