Transport Canada has issued a bulletin on the interim measures regarding compliance with IMO Tier III nitrogen oxides emissions standards set out in the Vessel Pollution and Dangerous Chemicals Regulations highlighting that it will not require compliance with the IMO Tier III NOx emissions standards until January 1, 2017.

DNV GL has issued statutory alert to remind that IMO NOx Tier III requirements will take effect in the North American and US Caribbean Emission Control Areas (ECAs) from January 1st 2016. The new requirements are applicable to all vessels with keel-laying on or after January 1st 2016 with an engine output of ≥130kW. DNV GL highlights that it is important to be aware of how to prove compliance and how the requirements will be enforced.

 DNV GL has issued Statutory News regarding the upcoming environmental regulations for emissions to air.The IMO Tier III requirements reduce nitrogen-oxide emissions (NOx) by approximately 76% in comparison to a Tier II engine. This requirement only applies to new vessels and engines. It poses a significant challenge to engine designers, as they need to apply NOx-reduction measures with the help of other engine technologies.Relevant for all vessels with keel-laying on or after 1 January 2016 with engine output of 130kW and above, when operating in North American and US Caribbean Sea Emission Control Areas.The IMO NOx-emission limits apply to diesel engines and depend on an engine’s maximum operating speed (n, rpm), as presented in the table below. Tier I and Tier II are global requirements, whereas Tier III standards only apply to current existing Emission Control Areas (ECAs) for NOx (North American and US Caribbean Sea).In future ECAs that regulate NOx emissions, the Tier III standards will apply to ships with keel-laying on or after the date of adoption of such an ECA.When the global Tier II limits came into force in 2011, engine-makers were able to tune the engines to comply with these new emissions limits. Tier III poses ...

  The Australian Maritime Safety Authority (AMSA) issued a Marine Notice to provide general information on Annex VI of the International Convention for the Prevention of Pollution from Ships (MARPOL). Annex VI of MARPOL contains regulations for the prevention of air pollution from ships and addresses the properties of marine fuels and engines, amongst other things. This Marine Notice focusses on MARPOL regulations that control emissions of sulphur oxides (SOx) and particulate matter, and nitrogen oxides (NOx). These controls are divided between those applicable inside Emission Control Areas (ECAs) and those applicable everywhere else. In Australia these regulations are given effect in the Protection of the Sea (Prevention of Pollution from Ships Act) 1983 and Marine Order 97 – Marine pollution prevention – air pollution. SOx and Particulate Matter Emissions SOx and particulate matter emissions are a function of the sulphur content of fuel. Accordingly, the SOx control requirements in MARPOL Annex VI provide for a progressive global reduction in the sulphur content of marine fuels to reduce the emission of SOx and particulate matter from ships. The current maximum sulphur content of fuel oil in areas other than ECAs is 3.5 per cent. This will be reduced to 0.5 ...

  Mitsui Engineering & Shipbuilding (MES) – the MAN Diesel & Turbo licensee – recently demonstrated the liquid-gas-injection concept successfully in Japan. The successful demonstration took place on 17 June, 2015 using the very first ME-LGI engine to ever be commercially produced. The engine, with the type designation 7S50ME-B9.3-LGI, is bound for a vessel currently under construction by Minaminippon Shipbuilding Co., Ltd. for Mitsui O.S.K. Lines, Ltd. Ole Grøne, Senior Vice President – Low Speed Promotion & Sales – MAN Diesel & Turbo described the event as a significant milestone in the development of Diesel technology and said: “The immediate market acceptance of our ME-GI (Gas Injection) engine confirmed the growing demand for low-sulphur, non-HFO options in the face of increasingly stricter sulphur limits in fuel. In turn, extending our dual-fuel engine programme with an ME-LGI unit that can run on liquid fuels was therefore a natural step.” He continued: “The interest in our ME-LGI engine confirms this dual-fuel, lowspeed trend and will offer even more alternatives to HFO, which – apart from methanol – will include LPG, dimethyl ether (DME), and (bio-) ethanol, as well as several other, low-sulphur, low-flashpoint fuels.” Grøne concluded: “We welcome our partners’ interest in ...
