11. www.alfalaval.com IMO MEPC.1/Circ.642 Slide 11 5 Definitions for the purpose of the Guidelines 5.1 Oily waste means oil residues (sludge) and oily bilge water. 5.2 Oil residue (sludge) means the residual waste oil products such as those resulting from the purification of fuel or lubricating oil from main or auxiliary machinery or separated waste oil from bilge water separators, oil filtering equipment or oil collected in drip trays, and waste hydraulic and lubricating oils.

12. www.alfalaval.com IMO MEPC.1/Circ.642 © Alfa LavalSlide 12 4.6 Re-generating fuel oil from sludge 4.6.1 Oil residue (sludge) may be used onboard as re-generated fuel. Oil residue (sludge) is collected in an oil residue (sludge) tank prior to processing (disposal) back into the fuel oil system as re-generated fuel oil. 4.6.2 Oily drains should be recorded in the oil record book as any other oil residue (sludge) collection. 4.6.3 Re-generation of fuel oil from oil residue (sludge) should be an approved means of disposal of oil residue (sludge) according to the Supplement to the IOPP Certificate. 4.6.4 The re-generating process may include filtration, decanting or purification to remove unwanted heavy parts from the oil residue (sludge).
