Cavitation De-fouling - Hull Cleaning Removal of marine growth
Hull Cleaning Sydney
Maintaining Ships, commercial and private vessels Hulls and Running gear is paramount,  Cavitation technology used by Wells MArine Hull Cleaning and marine growth removal Increase the improvement and perfromance of vessel’s operation.
proven reduced fuel consumption up to 20% and CO2 emission reduction of gases in the marine environment.

HULL CLEANING provides Stress Reduction of the propeller axis and the vessel’s machinery, The propeller s, Hull and rudder are cleaned simultaneously, to further enhance the performance of the vessel. Hull Cleaning provides Increased reliability & a great
Expansion of vessel’s maintenance cycles that usually require lift-out.

The underwater hull and running gear cleaning via cavitation polishing  and the maintenance of the smooth surfaces is vital in order to save energy and optimize the performance of the vessel. The rough fouled propeller and running gear leads to power loss, which can be up to 20% as well as an increase of fuel consumption. 

Wells Marine Diving Services , provides high quality underwater cleaning  and underwater propeller polishing, achieving immediate and effective reduction of fuel consumption and reduces the total running costs of the vessel.

Propellers convert mechanical energy to the propeller shaft to thrust energy of the water. The propeller blades function as a spoiler. The development of thrust that they generate is a result of flow which is generated around the blade. As the propeller turns the blades generate a pressure difference in the water, pushing the vessel forward or backwards, depending on the way that the propeller turns, as well as the pitch of the blades. There are fixed pitch propellers and variable pitch propellers. An important problem in vessel handling is the increase of fouling roughness to the propeller, as the fuel consumption and the emission of gaseous pollutants in the environment is increased and significant losses are caused to the propulsion system.

Surveys have shown that adopting regular underwater Hull Cleaning as an integral part of the scheduled maintenance of the vessel, significantly contribute in savings of the total fuel costs and long term vessel maintenance.

Although the surface area of the propeller is microscopic in comparison with that of the entire hull, the effect of a rough fouled propeller in a vessels fuel consumption is proportionately higher. It has been proven that the propeller, which has a smaller surface area, can create loss of energy gain, half of which the vessel's hull creates. If the Hull and propellers are rough with marine growth the performance of the vessel drops significantly.

Wells Marine Diving Services are the only Hull Cleaning Divers on sydney harbour water-ways to utilize the optimum Cavitation cleaning system of marine growth removal.
