Air Lubrication System ROI & Payback Calculator
Screen an air lubrication retrofit by separating gross propulsion savings from the electrical energy required to create the air layer. Compare laden and ballast operation, utilization, availability, blower or compressor demand, bunker and carbon value, retrofit cost, off-hire and multi-year lifecycle economics.

Engineering / commercial limitation: Air lubrication performance is highly vessel- and operating-profile-specific. Validate expected gross drag/fuel reduction and blower/compressor demand with vendor, CFD/model testing, sea trials or measured fleet data. This tool is an investment screen, not an EEDI/EEXI/CII/FuelEU/class calculation.
