UK P&I Club Legal Briefing The UK P&I Club has issued new Legal Briefing regarding the air pollution regulations.Air pollution from ships has been in the spotlight over recent years due to its increasing impact on the natural environment. The outcome has been a series of new regulations to limit exhaust and other atmospheric emissions from ships globally, regionally and nationally.MARPOL Annex VI sets global limits on ship exhaust emissions together with provisions for stricter emission control areas. For example in the North American Emissions Control Area, where the sulphur content of maritime fuel was limited to 1% in 2012, two UK Club members vessels have already been fined for not switching to low-sulphur fuel.By 18th June 2014 all European Union member states are expected to implement directive 2012/33/EU, which brings European national air pollution laws in line with MARPOL Annex VI. They and other countries are also introducing regulations which go beyond MARPOL Annex VI requirements.Ship owners need to be fully aware of the growing and stricter atmospheric emissions measures being introduced around the world. This update summarises the global, regional and national regulations currently in force and proposed. Ship owners should be aware of the growing and stricter ...

ICCT Working Paper The International Council on Clean Transportation (ICCT) has recenlty issued a Working Paper based on a survey of technical literature and industry reports which assess equipment costs, environmental side effects, urea and catalyst availability and disposal, and the overall system costs of SCR in the marine sectorICCT paper investigates the current status of selective catalytic reduction (SCR), a technology that is key to meeting Tier III requirements. Challenges and costs of the technology, including applicability to various engine and vessel types, potential environmental side effects, urea and catalyst availability and disposal, and anticipated system costs, are discussed. Based on this evaluation of technological capabilities and history of successful application of SCR technology to maritime vessels, no substantial equipment, supply chain, or cost barriers exist that would necessitate the delay of IMO's Tier III requirements.In 2008 the Marine Environmental Protection Committee (MEPC) of the International Maritime Organization (IMO) agreed upon progressively stricter limitations for nitrogen oxide (NOx) emissions from vessels based on their date of engine installation, with the strictest Tier III requirements to take effect in designated Emission Control Areas (ECA) beginning in 2016. At MEPC-66 in April 2014, an amendment that would delay the introduction of ...

During MEPC.65, IMO published two Unified Interpretations pertaining to Regulation 13 Nitrogen Oxides (NOx) of MARPOL ANNEX VI.

Can we reduce harmful emissions?

IMO issues new circulars The IMO has issued new Circulars and MEPC.1/Circ. 765 gives information on new retrofitting kits for MAN B&W S70MC and S50MC type engines.In accordance with the provisions of regulation 13 of MARPOL Annex VI, engines of more than 5 MW and a displacement per cylinder of 90 litres or above, installed onboard ships built between 1 January 1990 and 31 December 1999, should be fitted with methods for NOx emissions reduction (kits) when such kits are available and approved by an Administration.Ships with engines for which the kits are approved are required to be fitted with them at the first renewal survey of the IAPP Certificate which is scheduled 12 months from the date on which the Administration gives notice of the certification of the approved kit.According to MEPC.1/Circ. 764 and 765, the Danish Administration reported on the certification of the approved method for MAN B&W S70MC and SM50MC type engines on 11 August 2011. Therefore, installation of the kits for such engines will be mandatory no later than the first renewal survey for the IAPP Certificate which occurs on or after 12 August 2012, subject to commercial availability.IACS has informed the IMO that data provided ...

Engines of more than 5 MW -installed onboard ships built between 1 January 1990 and 31 December 1999 Normal 0 false false false MicrosoftInternetExplorer4 Operators are reminded that, when MARPOL Annex VI amendments were adopted, one new provision was to require that engines of more than 5 MW, installed onboard ships built between 1 January 1990 and 31 December 1999 should install methods for NOx emissions reduction (kits) when such kits are available and approved by an Administration.Ships with engines for which the kits are approved would have the obligation to fit them at the first renewal survey which is scheduled after 12 months from the date of which IMO issues the information on approved kits.We were made aware that the IMO has issued in October 2010 and in February 2011 MEPC.1/Circ. 738 (to view click here) and MEPC.1/Circ. 743 (to view click here) respectively with Information on Approved Methods Under MARPOL Annex VI. The NOx emissions reduction methods are promoted by MAN B&W and by Wartsila Switzerland Ltd respectively, andboth were approved by Germanischer Lloyd on behalf of the Danish and German Administrations respectively.The Appendix to the Notice of Compliance in MEPC.1/Circ 743 lists a number of ships (identified ...
