Hull cleaning

How to achieve a ‘clean’ fuel saving of US$2M between dry dockings

Underwater hull and propeller cleaning are established practices to help boost ship performance. Periodic cleaning can reduce fouling build-up and prevent increased ship resistance and fuel consumption in the period between dry dockings. Coupled with fuel consumption drivers, concerns over invasive species from biofouling as well as the need to maintain high levels of efficiency have made underwater cleaning a more attractive proposition to ship owners and operators.
During sailing, the hull of the ship is often overgrown by marine fouling which can increases roughness of hull surface. The roughness can increase the frictional resistance and automatically the ship needs more power capacity to operate at its service speed by using its engine up to Maximum Continues Rating (MCR).

Cleaning the hull can reduce emissions and improve the energy efficiency of the world's fleet. Hull fouling contributes greatly in increased emissions, and is the only main driver over which the ship owner has a large degree of control. Specifically, while the rate of marine growth on the hull is not on the ship owner's hands, the frequency and quality of periodic maintenance on the underwater hull is decided by the ship owner.
If fuel consumption increases by five tons a day, for instance, then it may be time for cleaning the propeller or hull. A combination of hull and propeller cleanings can deliver nearly 7% fuel savings on an Aframax tanker
