6 Collection and storage of oil residue (sludge) and oily bilge water

  6.1 An oil residue (sludge) tank or tanks are mandatory under regulation 12 in the revised MARPOL Annex I.

  6.2 An oily bilge water holding tank is arranged to receive the daily generation of oily bilge water before this water is discharged ashore or discharged through the 15 ppm bilge separator overboard. An oily bilge water holding tank is not mandatory, but will enable ships to operate safely during port visits, during operation in special areas and coastal waters and during periods of maintenance of the 15 ppm bilge separator.

  6.3 An oily bilge water holding tank will also provide additional safeguards in the purification of oily bilge water should quick-separating detergents be used for cleaning purposes.

  6.4 Oily bilge water holding tanks shall, if fitted, be noted in the Supplement to the IOPP Certificate.
