Lloyd’s Register has certified the first ever bolt on bilge polishing system designed to bring poorly functioning shipboard oil/water separators (OWS) into compliance with the strictest discharge requirements in the world. The Mycelx Technologies “SUB 5” Systems were awarded a LR Type Approval Certificate for being able to bring the strong oil emulsion specified by the International Maritime Organization’s (IMO) MEPC 107(49) Type C Oily Bilge Emulsion down from 3000 ppm to 0-5 ppm at flow rates up to 2.5 m3/h. As of January 1, 2005 the IMO will require that all newly built vessels over 400 gross tonnage carry an OWS, which meets their stringent new standards. The standards will also apply to all new installs and major retrofits of oil water separators on existing vessels.
