Air lubrication system retrofit
vendor claim — not yet independently measuredCompressor-fed air bubbles distributed under the flat bottom that reduce friction between hull and water. Works best on wide, flat-bottomed ships; carries a parasitic power cost for the compressors.

Measured real-world outcomes
The reduction range above is a vendor claim. We continuously detect completed retrofits in shipyard-visit, equipment and EU MRV emissions data and measure the actual AER change. Measured results are published per measure once at least 30 controlled observations exist — until then, treat vendor ranges as ceilings: real-world delivery is consistently at or below the low end.
