  1. Onboard Waste Treatment InstallationsRegulatory Review TRIPARTITE TOKYO 20th SEPTEMBER 2007

  2. BACKGROUND • Report on IMO decision at Tripartite 2006 • Review is a continuation of a previous adoption of the Japanese concept of Integrated Bilge Water Treatment System (IBTS) • IBTS introduced the concept of segregation of collection and treatment of leaked water and oil • Correspondence Group to provide report to DE 52 • MEPC to take a final decision in 2008

  3. BACKGROUND • Review aimed to: • bring further clarifications and simplifications on the terminology used • coordinate requirements in MARPOL Annexes I & VI • new regulation for the minimum capacity of the incinerator (in Annex VI) • remove from UI 15.1 allowance to reduce capacity of sludge tank if the ship has homogenisers or incinerators • bring clarifications on few entries of the ORB • supplement guidelines to ensure segregation and to ensure adequate design for components of waste treatment installations • bring more details on the conditions for type approval of the OWS

  4. EXAMPLE OF PROPOSED AMENDMENTS • MARPOL Annex VI, new Reg. 16 (10): The incinerator, installed with provisions of disposal of oil residues (sludge), while operating for 8 hrs daily at 75% of its designed capacity, should be able to incinerate an amount of oil residues (sludge) equal to 1.5% of the daily fuel consumption

  5. EXAMPLE OF PROPOSED AMENDMENTS

  6. EXAMPLE OF IBTS AMENDMENTS • Stricter requirement for type/shape of bilge primary tank (cascade type)

  7. CONSEQUENCES • Designs and arrangements need to be re-considered • IOPP Certificates will be modified • ORB may be amended • Would regenerated fuel still be used, at least in boilers? • What impact on existing installations? • USA proposed new standard to apply to all systems within few years. . if not phase-out!

  8. SUGGESTIONS • Follow the developments • Potential changes are positive • Be prepare for consequences (design and operations) • Initiate better arrangements ahead of the implementation date • Consider improvements to the existing installations • Phase-out might be avoided but not for inefficient systems
