The Republic of the Marshall Islands issued marine guideline referring to the application of Regulation 13 of MARPOL Annex VI Tier III requirements to dual fuel and gas- fueled engines

Hyundai Heavy Industries (HHI) announced that it produced the world’s first High Pressure Selective Catalytic Reduction (HP SCR) system for the dramatic reduction of NOx emission from 2-stroke marine engines.

Ships constructed on or after January 1, 2016 and entering into the North American or U.S. Caribbean Emission Control Areas (ECA) must comply with the Tier III NOx requirement of MARPOL Annex VI, Chapter 3, Regulation 13.5.1.1.

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.

Report from a study that quantified how much less air pollution is emitted from tanker ships due to the use of low sulfur fuels, shows air pollutants in Prince William Sound reduced by hundreds of tons per year.

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.

The slow steaming practice resutls in fuel saving and cuts in nitrogen oxides (NOx) emissions

EU Commission plans for more ambitious national caps on emissions of six key pollutants, including NOx, particulates and sulphur dioxide, were endorsed by Parliament. Air pollution causes about 400,000 premature deaths in the EU yearly, and the plans could save up to €40bn in air pollution costs by 2030.“Air pollution imposes enormous human and economic costs. It also damages the natural environment, through eutrophication and acid deposition, and it doesn’t stop at EU member states’ borders”, said lead MEP Julie Girling (ECR, UK). Her report was approved by a show of hands.“This legislation will help at all levels of governance in the member states, including the regional and sub-regional authorities who have engaged so vigorously in the process. There is a real bottom-up demand for action”, she added.“My report also pushes the Commission to ensure that the Real Drive Emissions (RDE) procedure is agreed on as soon as possible. We all agree that NOx must be dealt with urgently. The public are demanding action in this area following the recent revelations on the car industry”, she concluded.More ambitious capsMEPs approved the proposed caps for sulphur dioxide (SO2), nitrogen oxides (NOx), non-methane volatile organic compounds (NMVOC), methane (CH4) ammonia (NH3), and ...

 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 Fairplay Towage shipping company officially launched a new harbour tug featuring diesel gensets certified to IMO Tier III in Rotterdam on 10 July 2015. Powered by MTU Series 4000 engines featuring an SCR exhaust aftertreatment system, these diesel gensets are some of the first gensets in the world already certified as complying with IMO Tier III emission levels which come into force in 2016. Rolls-Royce delivered the two MTU 16V 4000 M63L main propulsion engines, each delivering 2,000 kW, one Series 4000 M23F 16-cylinder diesel genset with 1,520 kW and the MTU-developed SCR system. The exhaust aftertreatment system featuring selective catalytic reduction technology is combined with the diesel genset. MTU is a Rolls-Royce Power Systems brand which belongs to the Land & Sea Division of Rolls-Royce. “We're rather proud of being able to demonstrate the capabilities of this pre-series, space-saving solution to our client in the course of these trials”, says Nadine Buhmann, Head of Marine & Offshore Business at MTU. With trials in the Fairplay tug lasting some 10,000 hours, MTU is advancing its series solution for IMO Tier III marine engines. As of 2016, new vessels operating in the so-called Emission Control Areas off the North ...
