  1. Training Program MARPOL73/78 Annex VI-Regulations for the Prevention of Air Pollution From ShipsLesson 2 Dec.2006

  2. Reg. 12 – Ozone Depleting Substances • Any deliberate emissions of ozone-depleting substances prohibited • New installations which contain ozone-depleting substances are prohibited on allships • Installationscontaininghydrochlorflourocarbons (HCFCs) are permitted until 1 January 2020 • The use of Halon in fire extinguishing systems and equipment is already prohibitedfor new buildings • More restrictive requirements are in place regionally, e.g.. EU, USA

  3. Reg. 13 Nitrogen Oxides (NOx)Certification • Required for diesel engine with output greater than130 kW on ships keel laid on or after 1 January 2000, or major conversionsof engines after this date • Certification of engines according to the NoxTechnical Code • Engine International Air Pollution Certificate, EIAPP • Not for: • Emergency and fire pump diesels • Life boat engines • Boilers

  4. Reg. 13 Nitrogen Oxides (NOx) A major conversion of engine: • Engine replaced by new • Modification according to NO x code • Change in operational or technical parameter • Modification increasing the existing emission characteristics by simplified measuremente.g. changing camshaft, fuel injection system, or any other NOx-related settings or components • Increase of MCR by more than 10%

  5. Reg. 13 Nitrogen Oxides (NOx) EIAPP technical file • Contains essential information used during engine survey, and must be kept onboard all the time • Identification of components,settings and operating values influences its NOx emissions • Identification of allowable adjustments or alternatives for the components of the engines • Engine performance full recorded • Record book of engine parameter changes

  6. Reg. 13 Nitrogen Oxides (NOx) Allowable NOx Emission From Diesel Engines • The operation of applicable diesel engines are prohibitedexcept when the emission of nitrogen oxides from the engine is within the followinglimits: • 17,0 g /kWh when n is less than 130 rpm • 45,0 × n(-0,2) g/kWh when n is 130 or more but less than 2000 rpm • 9,8 g /kWh when n is 2000 rpm or more where n = rated engine speed (crankshaft revolution per minute) and the emissionof nitrogen oxides are calculated as total weighted emission of NO2

  7. Y/N Y/N Y/N Y/N Y/N Y/N Y/N EIAPP Certification and Onboard Verification (General guide, DNV as example) Engine above 130KW (Except from one used solely in case of emergency) Installed on vessel keel laid on or after 2000-01-01 Any major conversion made to the engine on or after 01/01/2000 No EIAPP Certificate required EIAPP Certificate required EIAPP Certificate already obtained EIAPP Certificate issued by DNV The certification process includes an emission test for compliance with the NOxrequirements on the manufacturer’s test bed, and approval of the Technical File. EIAPP Certificate issued by another IACS member Documents to DNV –Engine technical file -EIPPA issued by IACS member Documents accepted by DNV Vessel ready for IAPP initial survey according to Reg. 13 Annex VI Approach engine manufacturer for further assistance

  8. Reg. 14 Sulphur Oxides SOx • Globe Sulphur Cap: 4.5% • SOx Emission Control Area (SECA) 1 year after entry into force = Nowadays • SECA Sulphur Cap: 1.5% • End-of-pipe: 6.0g/kwh • SECA’s • The Baltic 2006-05-19 • North Sea 2007-11-19 • The English Channel 2007-11-19 For ALL ships!!! With or without IAPP Certificate

  9. EU-Requirements • EU opinion on Annex VI • Standard was past its sell out date • Inadequate, as Sulphur limit too high (4.5%) • New Directive • 0.2% S limit for MGO MDO in EU waters • 0.1% S limit for any marine fuel used berth from 1 Jan, 2010

  10. Exhaust Gas Cleaning System- Good Options? • As an alternative to using marine fuel oil with a 1.5% sulphur content in SECA’s, anexhaust gas cleaning system or other equivalent system may be used (abatementtechnologies). The emission criteria for such systems are 6 g SOx/kWh. • Will reduce theemission of particulate matter (PM). Particulate Matter is considered to be the nextfocal point of IMO. • Exhaustgas cleaning systems becoming a cost-beneficialalternative worthwhile exploring in future.

  11. Reg. 14 Operational Implications • Arrangements for 2-maybe 3 diff fuels • Availability –Bunking strategies • Switch-over(1-6 hrs?) will need to be completed when SECA • Handling of cylinder oils –2qualities may be required • More strict follow up through sample requirements, and control of documentation
