A new high-capacity oil skimmer completed sea trials. Designed by Ro-Clean Desmi, the skimmer uses two Desmi 250 vertical screw pumps, which have a well-proven ability to pump a wide range of oils from light to very heavy, perhaps emulsified. The weight of the skimmer head is only 690 lbs., and is powered hydraulically through floating hoses from a 150 hp diesel hydraulic power unit. The pumps are fitted with a cutting knife to handle most trash. The skimmer features a self-adjusting weir system, which automatically responds to the water movements, like gimbals, ensuring recovery efficiency.
