Tenneco  announced that it has introduced a complete urea dosing control, fluid handling and catalyst solution for selective catalytic reduction (SCR) after treatment, enabling large engines to meet EPA Tier IV and IMO Tier III regulations. The company will showcase the complete system at the 2014 WorkBoat Show in New Orleans Dec. 3-5, 2014 (Booth #2152). The system is designed specifically for high-horsepower engines in the marine, stationary and locomotive markets, providing precise and reliable delivery of liquid urea. It includes a proprietary, high-performance injector design, a precision mechatronic fluid delivery pump and customizable remote monitoring and controls. “We’re excited to introduce an advanced SCR system specifically designed and purpose-built for large engine applications,” said Timothy Jackson, chief technology officer, Tenneco. “The system provides a turnkey dosing solution which is compatible with a wide range of engine and after treatment architectures, and is supported by Tenneco’s extensive full systems integration expertise.” Tenneco’s large engine SCR system is designed to meet the requirements of major maritime classification societies including the ABS (American Bureau of Shipping), DNV (Det Norske Veritas), CCS (China Classification Society), KR (Korean Register of Shipping) and Class NK (Nippon Kaiji Kyokai). The system is currently being validated with ...

For the first time, all shipping companies calling at EU ports will have to measure and publicly report carbon emissions under a law approved by an overwhelming majority of the EU Parliament's Environment Committee. Sustainable transport group Transport & Environment (T&E) says that the law is weak - it only monitors fuel consumption instead of directly reducing it, and only covers CO2 and not air pollutants like SO2 or NOx - but it can still trigger fuel savings indirectly. The EU law will require ship operators to publicly report three metrics to measure the environmental performance of ships: the theoretical energy performance of the ship known as the Energy Efficiency Design Index (EEDI); its real-world fuel consumption; and its energy efficiency, that is, the amount of fuel divided by the amount of cargo. The more cargo a ship can carry using the same amount of fuel, the more efficient and cheaper to run it is. The publication of ships' real energy efficiency will provide shipping users in Europe and worldwide with transparent data to identify the most efficient ships and practices. This can trigger a virtuous cycle of increased competition among operators, which will enable fuel savings and emissions reductions. ...

Two new liquefied natural gas (LNG) powered sea vessels have recently been named on Teesside .  Operated by ship owner Anthony Veder, the new ships will carry Liquefied Ethylene Gas (LEG) from SABIC’s Wilton facility on Teesside to manufacturing plants in North-West Europe and Scandinavia.  The chemicals will be used to make a range of everyday items such as food packaging, PVC, detergents and adhesives.  The state of the art ships will drastically cut both sulphur oxides (SOx) and nitrogen oxides (NOx) emissions compared to the vessels they are replacing.  Switching to alternative fuels for ships, such as LNG, instead of traditional fuel oils is one of the solutions identified by Anthony Veder to help SABIC further improve its environmental performance.  “As a responsible global company, SABIC is committed to providing high-quality products to its customers while doing all it reasonably can in order to reduce the environmental impact of its operations,” said SABIC’s European Supply Chain Director of Chemicals Wouter Vermijs while attending the naming ceremony.  “We are proud to be the first chemical company in the world to be transporting our products on carriers running on LNG and to have an innovative partner in Anthony Veder.” The new ...

Commissioned by TCC Group, researchers at the University of Southern California (USC) Viterbi School of Engineering have made exciting progress in developing a more efficient method to initiate combustion, providing a breakthrough, technological step forward in clean shipping design. The technology, Transient Plasma Ignition (TPI), would allow marine diesel ships to reduce emissions, increase fuel economy and meet the International Maritime Organization's (IMO) stringent emissions mandate with minimal modifications. "We are thrilled to approach the cusp of a true clean shipping solution, especially on the heels of the recent United Nations Climate Summit," said Kenneth Koo, TCC Group chairman. "This epic endeavor strives to achieve reduction in harmful emissions and significant fuel consumption savings without additional investments into peripheral hardware such as scrubbers, chillers, hull coatings or fundamental modifications to the hull. It will be an immense boon for the shipping industry." TPI facilitates combustion by using energetic electrons that break the molecular bonds in fuel and air creating an alternate chemistry. This new environment allows for a more complete combustion, minimizing the amount of remaining unburned hydrocarbons, which translates to significant fuel savings and reduced emissions. TPI – Reversing Efficiency Losses, Recovering Energy & Reducing Emissions The technology aims ...

The MEPC adopted amendments to: • MARPOL Annex I regulation 43 concerning special requirements for the use or carriage of oils in the Antarctic area, to prohibit ships from carrying heavy grade oil on board as ballast;   • MARPOL Annex III, concerning the appendix on criteria for the identification of harmful substances in packaged form; and • MARPOL Annex VI, concerning regulation 2 (Definitions), regulation 13 (Nitrogen Oxides (NOx) and the Supplement to the International Air Pollution Prevention Certificate (IAPP Certificate), in order to include reference to gas as fuel and to gas-fuelled engines.    The Marine Environment Protection Committee (MEPC) of the International Maritime Organization (IMO) met for its 67th session from 13 to 17 October 2014, at IMO Headquarters in London.   Source: IMOIn the outbreak, I was explicit with you propecia before and after has changed my subsistence.

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 ...
