Upgrade to new 107(49) OWS system

 There are a variety of certified OWS on the market. Before considering an upgrade, it is important to evaluate the ship’s and company’s circumstances. Excessive oily waste generation, excessive introduction of clean water into the bilge, and contaminants (e.g., solvent and detergents, engine-room soot, and small particulates) introduced into bilge water can contribute to operating problems with any OWS. A new 107(49) OWS should be able to handle the contaminants found and expected to be found in the bilge. As well, a new 107(49) OWS should be able to handle the volume of oil, water and oily emulsions generated by ship operations. Some upgrades may require retrofitting of pumps, holding tanks and extensive piping arrangements. Bilge water treatment systems meeting resolution MEPC.107(49) standard systems are designed using polishing/filtration. Selection of an OWS upgrade by a marine engineer should evaluate which polishing technology is most appropriate for a particular shipboard environment.
