11 Example of an on-board system for oil residue (sludge) incineration

  11.1 General

Oil residue (sludge) from oil residue (sludge) tanks may be incinerated in incineration systems onboard. Oil residue (sludge) tanks are not a means for disposal of oil residue (sludge), but for retention of oil residue (sludge) for disposal.

  11.2 Oil residue (sludge) incineration systems

An oil residue (sludge) incineration system may be composed of:

  • .1 steam boiler or heater of thermal fluid systems or an incinerator;

  • .2 oil burner;

  • .3 oil sludge processing system; and

  • .4 service tanks for oil residue (sludge).

  11.3 Oil residue (sludge) processing systems

The oil sludge processing system consists of:

  • .1 oil residue (sludge) tank intended as servicing the oil residue (sludge) sludge incinerating system;

  • .2 oil residue (sludge) preheating system;

  • .3 filter; and

  • .4 homogenization system.

  11.4 Oil residue (sludge) service tank

The oil residue (sludge) service tank should be listed under item 3.1 in the Supplement of the IOPP Certificate, as it is provided with means for drainage of water (disposal) and subsequent disposal of the oil residue (sludge) in the oil residue (sludge) incineration system.

The oil residue (sludge) service tank should be provided in addition to the oil residue (sludge) tank for oil residue (sludge) and other waste oils. It should be equipped with suitable drainage facilities terminating as provided for in regulation 12.2.2 of MARPOL Annex I . With a view to improving combustibility and calorific value, a fuel oil supply connection should be provided.

  11.5 Homogenization system

The homogenization system should assure that the entire contents of the oil residue (sludge) service tank should be processed into a homogenous and combustible mixture. This system should be put into operation following adequate draining of the tank. A device for continuous indication and monitoring of the water content of the oil sludge should be provided.
