MARPOL Annex I BILGE WATER To consider when designing a Bilge water system It is very easy to get the MEPC.107(49) Type Approval Cer<ficate! The test standard MEPC.107(49) only require test of emulsified bilge water for 2,5 hours. ! Performance Most of the bilge water onboard is emulsified due to the use of different chemicals and chemical addiGves. 2 Can the separator handle chemical emulsions and all chemicals onboard? Ask for the list of approved chemicals which the separator can handle! Opera<onal cost What is the operaGonal cost per m3 treated emulsified bilge water? Including the costs for consumables such as filter elements and chemicals and pumping ashore. 3 Worldwide Service network Spare parts, service AND training for the crew! How is the bilge water system designed? Is the system properly built with heaGng and seqling tanks? IBTS? 4 1 5
