Air Lubrication System ROI & Payback Calculator
Estimate air lubrication system fuel savings, compressor energy penalty, payback, NPV and ROI for a ship or vessel. Compare laden and ballast performance, bunker cost, carbon value, retrofit CAPEX, annual maintenance and lifecycle cash flow.
Fuel & ALS Performance
Use a net annual fuel-saving estimate that already reflects blower or compressor energy for a fast screening case.

Air Lubrication System & Utilization
Advanced mode calculates gross propulsion saving and then subtracts the equivalent fuel required to supply ALS electrical power.

Air Lubrication ROI Results
Simple ALS financial screen
Enter project data
Enter propulsion fuel consumption, expected ALS saving,
bunker price and project cost to calculate air lubrication
payback, NPV and ROI.
Planning estimate only.
Actual air lubrication system performance depends on hull form,
draft, speed, sea state, air distribution, compressor or blower
demand, hull condition, operating profile, machinery integration
and system availability. Validate expected savings with
vessel-specific engineering, trials or measured performance.
Confirm retrofit scope, structural and machinery requirements,
class approval and installation constraints before an investment
decision. This tool does not replace official CII, EEXI, EEDI,
EU ETS, FuelEU or class calculations.
