Heat & Operating Profile
Enter a vessel-specific operating case. Recoverable heat should already reflect temperature, pinch-point, fouling and practical heat-exchanger constraints.
MT/day during WHR-eligible operation.
% of main-engine fuel energy practically recoverable.
Pumps, fans, working-fluid systems and auxiliaries as % of gross WHR output.
g/kWh displaced generation.
% of eligible main-engine fuel for backpressure or other engine-side effects.

WHR Technology & Operating Profile
Heat-exchanger fouling / machinery degradation before maintenance recovery.
kW average auxiliary load that can accept WHR output.
Waste Heat Sources
Available thermal power and practically recoverable share are entered separately so low-grade heat does not receive the same credit as high-temperature exhaust.
Power Conversion & Engine Penalty
