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.

  5.3 Oil residue (sludge) tanks are the tanks which hold oil residue (sludge) directly from which oil residue (sludge) may be disposed through the standard discharge connection or any other approved means of disposal.

  5.4 Oily bilge water holding tanks are tanks collecting oily bilge water prior to its discharge, transfer or disposal.

  5.5 Regulations referred to in these Guidelines are those contained in MARPOL Annex I adopted by resolution MEPC.117(52).

  5.6 Oil residue (sludge) incineration systems are systems proving incineration of oil residue (sludge) generated on board seagoing ships. Oil residue (sludge) incineration systems could be:

  • .1 main and auxiliary steam boilers with appropriate oil residue (sludge) processing systems;

  • .2 heaters of thermal fluid systems with appropriate oil residue (sludge) processing systems;

  • .3 incinerators with appropriate oil residue (sludge) processing systems designed for sludge incineration; or

  • .4 inert gas systems with appropriate oil residue (sludge) processing systems.

 Oil residue (sludge) incineration systems shall conform to regulation 16 in MARPOL Annex VI

  5.7 Oil residue (sludge) drain tanks are:

  • .1 tanks intended to receive separated sludge from purifiers and other oil residue (sludge) drains;

  • .2 tanks without any means for disposal of sludge as listed in items 3.2 and 4 in the Supplement to the IOPP Certificate, and drains; and

  • .3 tanks with suction connection for a sludge collecting pump only capable of discharging to the oil residue (sludge) tank(s) listed in item 3.1 in the Supplement to the IOPP Certificate.

  5.8 Sludge collecting pumps are pumps capable of taking suction from any oil residue (sludge) producing equipment or tank, other than an oil residue (sludge) tank(s), and discharging only to oil residue (sludge) tank(s).

  5.9 Separated sludge is sludge resulting from purification of fuel and lubricating oil.
