Alfa Laval PureNOx technology has long been the choice for water treatment in Exhaust Gas Recirculation (EGR), one of the main strategies for Tier III NOx compliance.
Port Of LA Sets New Record For Cutting NOx Emissions While Moving More Cargo Than Ever
Emissions of nitrogen oxides (NOx), a key component of smog, are down an unprecedented 60 percent compared to 2005 emissions levels, their lowest level to date.
First Ship With IMO Tier III EIAPP Certified Wärtsilä Engines Is Launched
Launch of the L’Astrolabe, a polar logistics vessel fitted with a complete Wärtsilä propulsion machinery package and NOR SCR exhaust gas cleaning systems for all the main engines, took place on July 12.
DNV GL Releases Updated DNV GL NOx Tier III Compliance Guide
DNV GL has developed a new brochure to offer a set of best practices for the design of ships subject to NOx Tier III requirements. It also offers guidance on the considerations that should be taken into account.
Environmental Ship Index To Also Evaluate CO2 Performance
This makes the index the first sustainable quality mark in international shipping that includes the performance and the reduction in CO2 in its assessment.
Study: A Levy On Emissions Can Reduce Ship NOx Emissions By 70%
A levy on nitrogen oxides (NOx) emissions with revenues earmarked to fund the uptake of NOx abatement measures is the most promising tool to reduce these ship emissions by up to 70%, anew study by environmental consultancy IVL and CE Delft reveals
Upcoming Environmental Regulations For Emissions To Air – IMO NOx Tier III
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.
Current Issues And New Regulations Concerning The On-Board Blending Of Fuels
For the past two decades, the global push to reduce greenhouse gasses, coupled with the soaring price of fuel oil and insecurity of fuel supply, has focused governments on the need for alternative resources. The European Community has decreed that sustainable fuel policies should be adopted.
IMO MEPC 66 NOx Regulations And Arguments On Selective Catalytic Reduction (SCR) Technology
On April 4, 2014, IMO MEPC on its 66th session, agreed on stricter requirements for vessels’ NOx emissions in specific areas, the so called NECAs. During this session the entry into force date of these requirements has been also agreed, although until the final MEPC decision, there was a disagreement for this matter from a number of countries headed by Russia.
Fuel Oil Change Over Procedure for Ship’s Main and Auxiliary Engines
Changing over of fuel oils in ship’s main engine and generator is important to keep a check on NOx and SOx emissions while entering Emission control areas (ECA) as mentioned under MARPOL Annex VI- Prevention of air pollution by ships. Find out more about the changing over procedures of fuel on ship’s marine engine and generator.
