Verify SFOC compliance against IMO baseline for engine generation/year. WH28 (181 g/kWh) meets latest efficiency standards; WD12 (212 g/kWh) acceptable for auxiliary duty. Measure actual fuel consumption during sea trials.

Verify IMO EIAPP (Engine International Air Pollution Prevention) certificate. Check NOx (nitrogen oxide) and smoke number measurements. Confirm diesel particulate filter/SCR compliance status for engines built post-2016 for Tier III zones.

Inspect fuel polishing systems and separator effectiveness. Verify fuel storage tank cleanliness (ISO 4406 cleanliness code 16/14/11 minimum). Check injector spray patterns under load. For HFO-capable engines (CW200, CW250), confirm proper viscosity and pour point.

Measure outlet water temperature differential (target: 3-5 degrees C drop across cooler). Check intercooler fouling (common in 170, 6WH17, 8WH17). Inspect jacket water and lube oil temperatures under full load. Perform ultrasonic thickness test on cooler tubes for erosion corrosion.

Measure turbocharger boost pressure against load curve. Check lube oil pressure to turbo (minimum 1.5 bar). Perform borescope inspection for carbon buildup in compressor wheel. Monitor turbo case temperature with IR gun (typically <100 C at inlet manifold). Confirm oil drain line unrestricted.
