The 30% Lever in the Engine Room: Why Pump Efficiency Is the Overlooked Compliance Asset in 2026
Pumps consume 20–40 % of auxiliary power on most vessels, yet the majority still run on outdated IE1/IE2 motors with fixed-speed drives. Upgrading to IE4/IE5 motors plus Variable Frequency Drives (VFD) and intelligent controls can deliver 20–50 % (and up to 75–90 % in part-load) energy savings – with payback periods of only 12–24 months.In this episode I explain why pump efficiency has become one of the fastest, cheapest and most powerful levers to improve EEXI and CII ratings, reduce EU ETS and FuelEU Maritime costs, and cut bunker expenses – without waiting for new fuels or major drydock investments.You’ll learn:
