MAN-powered vessel gets Tier III compatibility certificate

MAN Diesel & Turbo has been awarded a Tier III-compatibility certificate by the DNV-GL classification society for MAN 8L21/31 four-stroke engine aboard a DFDS Seaways ship with a retrofitted SCR (Selective Catalytic Reduction) system. While the engine alone meets IMO Tier II emission criteria, the SCR system for NOx reduction raises the whole system to the standard demanded by IMO Tier III rules. The vessel in question, the ‘Petunia Seaways' is a cargo ship that sails a regular North Sea route between Gothenburg, and Immingham, respectively Ghent for DFDS Seaways. Its SCR system greatly reduces the level of nitrogen oxides (NOx) from the engine's exhaust gas. Since September 2012, when one of Petunia Seaways' 8L21/31 auxiliary engines was retrofitted with a SCR system, it has played a major role in the testing of this new technology. As such, the system has proven daily that freight ships can now meet the strict emission levels laid down by IMO Tier III where NOx emissions have to be reduced in certain areas by 75% compared to current limits. "For the last 8,800 hours, this particular auxiliary engine of the Petunia Seaways has consistently met Tier III NOx limits under real life operating conditions ...

IMO Council Outcome

112th Session, 16-19 June 2014 The IMO Council held its 112th Session (C112) from Monday 16 through Thursday 19 June 2014 under the Chairmanship of Mr J Lantz (USA) and his Vice Chair, Dr D Ntuli (SOUTH AFRICA). It will be recalled that the IMO Assembly (of all its 170 Member States) met at the end of last year and elected 40 of its constituent Member States to effectively act as its executive body until it assembles again in the customary 4 year cycle. The meeting was thus a first for the newly elected Council and much of what was discussed centred around the governance and good practices of the IMO under its Secretary-General, Mr Koji Sekimizu. Such minute detail will be of lesser interest to InterManager members but this short report seeks to highlight those areas which impinge more directly on our business, in particular, recommendations made by the various Committees to the Council.Strategy, Planning and ReformThe Risk Management Framework proposed by Germany, will only be applied to the Secretariat's Business Plan until such time as the Council agrees to revisit the issue. A fundamental review of the Strategic Plan will be conducted by an external consultant as proposed ...

Stricter air pollution regulations on the horizon

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 ...

Feasibility of IMO Annex VI Tier III implementation using SCR

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 ...
