What is Niche Cleaning?
Biofouling is what we call the build-up of marine life on the submerged parts of vessels. It can include Acorn Barnacles, Algae, Tubeworm, Bryozone, Mussels and Oyster etc. Biofouling is not only found on the flat hull surface, but it can also be found in niche areas such as the Propeller, Rudder, Sea Chests and Anchor Wells to name a few. It is crucial for Niche Areas to be maintained.
Who Insists on Niche Cleaning?
The countries that require niche areas to be maintained are mainly Australia, New Zealand, and United States of America. IMO Guidelines on biofouling management are under revision with reference to niche cleaning. The emphasis on the importance of niche cleaning is growing and becoming more prominent in different countries.
What Technology is used?
Currently, the technology used to remove Biofouling on vessels have been mechanical machines using brushes that are in contact with the hull surface and/or fouling layer to remove the biofouling. The material of the brush varies as it is dependent on the type of fouling to be removed.
How can Schomberg assist in Niche Cleaning?
The Schomberg proprietary hot water generator control technology with pressurised combustion chambers is designed to fill and circulate the Sea Chests and Thruster Cavity with hot water, maintaining the inner temperature at 70 degree Celsius for 60 minutes. This methodology kills the Alien Invasive Species and Biofouling. The circulated return hot water is pumped through a series of filtration systems to remove any impurities prior to being reheated and circulated.
When is it time to take Niche Cleaning seriously?
Conclusively, Niche Cleaning is becoming imperative as many countries are introducing unilateral requirements. Regulations are constantly changing, but Niche Cleaning is becoming more of a necessity.
