Project Overview
In April 2026, Kingfisher successfully completed a custom high-efficiency propeller retrofit for M/V ANANYA NAREE at Shanhaiguan Shipyard, China, achieving full  compliance with IMO EEXI & CII requirements and delivering measurable fuel  savings.
The new fixed-pitch propeller was specially designed based on the vessel’s original propeller, engine characteristics, and actual operating profile, using advanced  lifting-line and lifting-surface hydrodynamic analysis.
_{Key objectives:}
         lReduced fuel consumption
         lOptimized service speed 

         lLower CO₂emissions 

         lImproved propulsion reliability

Kingfisher provided full on-site technical support during drydock and sea trial phases, ensuring precise installation and system alignment.
Scope included:

        lOriginal propeller removal
        lNew propeller blue fitting & pressing-up 

        lShaft alignment checks and bearing jack-up test 

          lMain engine crank web deflection measurement 

          lSea Trials & Performance Verification 

         lComprehensive sea trials were conducted, covering:
          Speed trial
         TVC / torque verification
         Fuel Oil Consumption (FOC) measurement 

          Results: 7% Fuel Consumption Reduction 

Analysis of sea trial and operational data shows an average fuel consumption  reduction of approximately 7%, delivering immediate economic and environmental benefits.
Propeller optimization remains one of the most cost-effective short-term solutions for decarbonization.

This project demonstrates how targeted hydrodynamic upgrades can deliver fast,  verifiable returns without major machinery modification.
