Underwater hull cleaning and propeller polishing saves fuel


Cleaning a light slime can yield up to 7 to 9 percent reduction in propulsion fuel consumption.


Cleaning a heavy slime saves up to 15 to 18 percent reduction in propulsion fuel consumption.


Cleaning a heavy macro fouling saves up to 20 to 30 percent reduction in propulsion fuel consumption.

Hull cleaning
leads into predictable cost control.

Design speed of a vessel is 16 knots/hour

Fuel consumption is 40 ton of fuel per day

In money this means 40 x 700 US$ = 28.000 US$

After hull cleaning saving 20% = 5600 US$ per day
