Pilot ALS installation delivers reported 7% fuel saving

A pilot installation on Norwegian shipowner Saga Shipholding Norway vessel Saga Future recorded a gross fuel saving of 7% over 10 months of operation, according to Minke Marine.

The company said the installation involved an investment of less than US$485,000, does not require compressors, and that the trial also recorded lower emissions.

The system operated aboard the 55,000-dwt general cargo vessel for 10 months and performance was assessed using short-term one-hour system-on and system-off cycling, based on DNV’s March 2025 Recommended Practices for ALS Performance Verification.

The release added that fuel flow, torque and speed through the water were measured with constant main engine rpm.

Minke Marine cofounder Giles Candy said, “We’d like to thank Saga for its belief in the project.”

Mr Candy also said the trial data was consistent with crew records and with analysis conducted by Saga and vessel manager Anglo-Eastern Ship Management HK.
