Chief’s Energy Efficiency Audit Tool

This is not just a checklist; it is a Strategic Energy Management Framework. Most audit templates focus on “did you turn off the lights?” This template focuses on SFOC curves, thermodynamic entropy, and parasitic load management.

Chief Engineer’s Strategic Energy Audit

Propulsion Optimization & Thermal Efficiency Framework (v.2025)

Chief’s Note: Efficiency is not found in one place. It is the sum of 1% gains across the entire plant. Use this audit during deep-sea passages to baseline your CII performance.
Phase I: Main Engine & Combustion Optimization Propulsion
OK Optimization Parameter Metric/Target
☐ Specific Fuel Oil Consumption (SFOC) Deviation Compare daily consumption vs. sea trial curve at current engine load. < 2% Variance
☐ Scavenge Air Cooler (SAC) Delta-T Optimization Verify scavenge temp is maintained 3-5°C above dew point to maximize density without condensation. Dew Point + 5°C
☐ Fuel Viscosity & Injection Temperature Confirm viscosity at injectors is 10-12 cSt for optimal atomization/combustion efficiency. 12 cSt Max
Phase II: Auxiliary Power & Parasitic Load Management Electrical
OK Optimization Parameter Metric/Target
☐ DG Load Factor Optimization Avoid running multiple generators at < 50% load. Maximize SFOC efficiency by loading a single unit to 75-85%. 75-85% MCR
☐ HVAC Recirculation Strategy Adjust fresh air intake ratio based on outside ambient temperature to reduce compressor load. 30% Fresh Air
Phase III: Waste Heat Recovery & Steam Systems Thermal
OK Optimization Parameter Metric/Target
☐ Economizer / EGB Backpressure Audit Soot blow frequency adjusted for ΔP. High backpressure increases ME fuel consumption. ΔP < 200 mmWC
☐ Steam Trap Integrity Survey Ultrasonic/Visual check for blowing traps. Every leaking trap is fuel burnt in the boiler. 0 Leaks
Phase IV: Hydrodynamic Interface Hull
OK Optimization Parameter Metric/Target
☐ Propeller Slip Analysis Compare engine distance vs. GPS distance. Sudden slip increase indicates fouling or shallow water effect. Baseline + 1%
☐ Trim Optimization (Static & Dynamic) Coordinate with Bridge to achieve optimal trim for current displacement/speed. Optimum LCF
