Underwater Cleaning & Propeller polishing effects to Fuel Consumption

Hello Queseanias,

Due to SEEMP Part III, action plans for improving vessels are projected for categories D & E. Underwater cleaning & Propeller polishing are alternatives, any reference for that case how much consumption rates are affected such as; 2% - 5%, etc.

Have a nice week ahead,

Hi @ege,

I am coming from the underwater hull cleaning “family” (Maker of an autonomous robot ourselves) so don’t take my advice as granted but something to further look at.

What we have seen after many operations (some of them verified from third-parties) is that the effect is definitely positive, starting from a small number (2%) and potentially going up to even a two-digit number. And this only by focusing on the vertical sides.
So, the effect might vary a lot because many factors can affect it, like items related to the hull status (affecting the fouling growth rate, like paint quality/suitability/application, area of operation, idle time, etc.) and items related to the way that the evaluation of the effect takes place (proper sensors onboard, proper tools at the office for analysis, historical data, etc.). It is always challenging to estimate (or, even more, measure) the effect that an item has on the performance, no matter if the potential effect is small (where there is also the higher chance of a statistical error) or bigger.

Hope I gave you something to further think of. :slight_smile:
