Yalah Subsea Nigeria Limited

Many of our customers who have availed themselves of this service have noticed a remarkable difference in their fuel efficiency after each cleaning.
When the propeller is kept in an ultra-smooth condition (Rubert A or A+) that’s where the real fuel savings and speed can be achieved.

This finish can only be accomplished with in-water polishing of the propeller.

The ‘bottom line’ for the customer depends on the cost of the service deducted from the financial savings resulting from the polish.  Provided the job is done properly, the cost of the underwater polish will only be a small proportion of the fuel savings, and therefore the most important factor to be considered by the customer is the quality of the polishing.

The sole purpose of polishing a propeller underwater is to reduce the surface roughness.

Removing marine growth and calcium deposits is giving a super smooth surface which is inhospitable to marine organisms as well as being beneficial to the efficiency of the propeller performance and reducing stress on the propeller shaft and ship’s engines.

The purpose of underwater hull cleaning is to remove biological roughness or fouling. A build-up of marine fouling can lead to increased drag, resulting in a detrimental impact on a vessel’s hydrodynamic performance and hence the relationship between speed, power performance and fuel consumption.  Fouling, particularly in the case of a prolific build-up of hard or shell fouling like barnacles or tubeworm, can cause turbulence, cavitation and noise, frequently affecting the performance of sonars, speed logs and other hull mounted sensors.

Proper cleaning removes all traces of fouling and does not remove or damage the coating or cause any increased surface roughness. Underwater cleaning is performed either by a diver with brushers or by a remotely operated vehicle (ROV) controlled from land. 

Depending on the degree of marine fouling, vessel size, vessel segment, operation profile and trading areas a reduction in the range of 1% to 5 % on main engine fuel consumption can be expected.
