 Regulations for the Prevention of Air Pollution from ShipsThe following table is a proposed checklist for Owners preparing for the implementation of Annex VI of MARPOL 73/78 and the initial survey to obtain the required International Air Pollution Prevention (IAPP) Certificate. 19 May 2005 Annex VI to MARPOL entered into force. The revised Annex VI to MARPOL was adopted by IMO on 10 October 2008. The sulphur oxide (SOx) and Particulate Matter emissions from ships will in general be controlled by setting a limit on the sulphur content of marine fuel oils as follows. The sulphur content of any fuel oil used on board ships shall not exceed the following limits: - 4.50% m/m prior to 1 January 2012 - 3.50% m/m on and after 1 January 2012 - 0.50% m/m on and after 1 January 2020 Requirements within Emission Control Areas For the purpose of the regulation, Emission Control Areas shall include: - The Baltic Sea area as defined in regulation 1.11.2 of Annex I, the North Sea as defined in regulation 5(1)(f) of Annex V - Any other sea area, including port areas, designated by the Organization in accordance with criteria and procedures set forth in appendix III to this Annex While ships are operating within an Emission Control Area, the sulphur content of fuel oil used on board ships shall not exceed the following limits: - 1.50% m/m prior to 1 July 2010 - 1.00% m/m on and after 1 July 2010 - 0.10% m/m on and after 1 January 2015 The sulphur content of fuel oil referred to in paragraph 1 and paragraph 4 of this regulation shall be documented by its supplier as required by regulation 18 of this Annex. Those ships using separate fuel oils to comply with paragraph 4 of the regulation and entering or leaving an Emission Control Tier I (current limits) For diesel engines installed on ships constructed from 1 January 2000 to 1. January 2011 allowable emissions of total weighted NOx depending on engine speed, n, are: 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 Tier II For diesel engines installed on ships constructed on or after 1 January 2011 allowable emissions of total weighted NOx depending on engine speed, n, are: - 14,4 g/kWh when n is less than 130 rpm - 44,0 × n(-0,23) g/kWh when n is 130 or more but less than - 2000 rpm - 7,7 g/kWh when n is 2000 rpm or more Tier III Ships constructed on or after 1 January 2016 will have additional limitations when operating in an Emission Control Area. For the purpose of NOx emissions no Emission Control Areas (ECAs) have yet been designated, but it is expected that both the Baltic Sea and the North Sea will be designated well ahead of 1 January 2016. For Tier III ships operating in the NOx ECAs the allowable emissions of total weighted NOx depending on engine speed, are: - 3,4 g/kWh when n is less than 130 rpm - 9,0 × n(-0,2) g/kWh when n is 130 or more but less than 2000 rpm - 2,0 g/kWh when n is 2000 rpm or more Tier III limits will not apply to engines installed on a ship with a length of less than 24 metres when it is designed and used solely for recreational purposes, or an engine installed on a ship with a combined nameplate diesel engine propulsion power of less than 750 kW if it is demonstrated that the ship cannot comply with the standards set forth in paragraph 5.1.1 of this regulation because of design or construction limitations of the ship.
