Title: 2.3 Waste Management

2.3 Waste Management Revised IBTS
  • Regulation 12 Tanks for oil residues
  • Integrated Ballast Treatment System
  • Separation of Clean and Dirty Drains
  • Pre-treatment of Oily Drains
  • Minimum Sludge Tank Capacity
  • Revoking of UI 15.1.5 (Minimum Sludge Tank
    Capacity is 50 if an Homogenizer or Sludge
    Incinerator is fitted)

Regulation 12 Tanks for Oil Residues
  • 2 Oil residues (sludge) may be disposed of
    directly from the oil residue (sludge) tank(s)
    through the standard discharge connection
    referred to in regulation 13, or any other
    approved means of disposal. The tank(s)
  • .1 shall be provided with a designated pump that
    is capable of taking suction from the oil residue
    (sludge) tank(s)
  • .2 shall have no discharge connections to bilge
    system, oily bilge water holding tanks, tank top
    or oily water separator and
  • .3 may be fitted with drains, with manually
    operated self-closing valves, for the collection
    of settled water or an alternative arrangement,
    provided such arrangement does not connect
    directly to the bilge piping system.

Integrated Bilge Treatment System
  • Clean Drains
  • Main Engine Air Cooler Drain
  • Cooling Fresh Water, Sea Water
  • Steam Drain, Boiler Water
  • Drain to the Clean Drain Tank and can be Pumped
    directly overboard.

Integrated Bilge Treatment System
  • Oil Residues (Sludge)
  • Hydraulic Oil Pump Tank Coaming Drain
  • Waste Oil Pump Tank Coaming Drain
  • LO Pump Tank Coaming Drain
  • Bilge Equipment Coaming Drain
  • Main Engine Scavenge Drain
  • Compressed Air Drain
  • Purifier Sludge
  • Bilge Primary Tank (Oil Side)
  • Workshop Drain
  • Drain to the Sludge Tank for discharge Ashore or

Integrated Bilge Treatment System
  • Oily Bilge Water
  • Engine Room Scuppers
  • Engine Room Bilges
  • Drain/Pumped to Primary Bilge Tank for
    pre-treatment to separate oil and water phases.
  • Water side drains to Bilge Holding Tank and
    discharge via OWS
  • Oil Side Drains to Sludge Tank

Example of a Bilge Primary Tank
Minimum Sludge Tank Capacity
  • Incinerators
  • Operation during Manned periods only, e.g. 8
    hours per day.
  • Port stays and stand by passages restrict
  • Homogenizers
  • Effectiveness
  • UI 15.1.5 will be revoked with amendments to
    MARPOL Annex I
