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 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.
This makes the index the first sustainable quality mark in international shipping that includes the performance and the reduction in CO2 in its assessment.
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
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.
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.
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.
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.
The HNS Convention is an acronym for the IMO’s International Convention on Liability and Compensation for Damage in Connection with the Carriage of Hazardous and Noxious Substances by Sea.
The capsizing of a chemical tanker ship – Ievoli Sun – led to huge causes of concern on account of huge potentiality of maritime ecosystem pollution. Find out more about the chemical tanker Ievoli Sun incident inside the article.
Find the impacts of the third Emission Control Area – The North American Emission Control Area which is applicable for ships trading in areas off the Coasts of Canada, The United States and French majorities of Saint.
Among the various emission control applications used in the shipping industry, Selective Catalytic Reduction (SCR) System comes out to be the most efficient in effectively reducing ship’s NOx emission by 90-95%. Find out more about SCR systems inside the article.
SOx and NOx substances in Ship’s emissions are the main reasons for pollution and degradation of environment. Ten technologies/ methods mentioned in these article helps to keep a check on these substances.
SEEMP is a special tool of IMO to measure and control GHG emission from the already existing shipping fleet. Know more about the plan inside the article
Nitrogen oxides or NOx is major marine air pollution gas from ship & result of nitrogen present in air reacting with oxides under certain operating conditions.
Safety of Life at Sea (SOLAS) and Convention for Prevention of Marine Pollution (MARPOL) stands as two solid pillars that support the maritime industry.
