water-oil mixtures and Bilge small footprint rotary lobe pumps for Marine
A water protection ship, operated by the water and maritime authorities, is used not only for exhibiting and collecting uniform light buoys, as cutwater, for firefighting, emergency towing, supervision of the maritime traffic, but also for hazardous substance emergency abatement. For this purpose, the ship, which is 78.91 m long, is equipped with two skimmer arms, which is able to collect the oil-seawater mixture from the water surface, in case of any disaster..
