CII - SFOC & Fuel Mix Quick Check
Quick CII check from main-engine SFOC, auxiliary-engine load, and ship-size parameters - for design-stage sensitivity.
Total fuel
27.2t/day
CII (at sea)
3.31gCO₂/dwt·nm
Formula, assumptions, and limits
At-sea CII is lower bound; add port days (denominator grows slower than numerator → CII worsens). Annual CII = fuel-weighted mix of at-sea and in-port operation.
