The new Wärtsilä NOx Reducer will be fitted to two new fishing vessels under construction at the Celiktrans yard in Turkey.
The ships are owned by HB Grandi, one of Iceland’s fishing vessel operators. The order was received during the fourth quarter of 2013 and Wärtsilä’s equipment is scheduled for delivery in the second and fourth quarter of 2014.
The upgraded version of Wärtsilä NOx Reducer features a flexible and more compact design to enable easier and faster onboard installation. It is also compatible for both marine diesel fuel (MDF) and heavy fuel oil (HFO) engine operation. The auxiliary units have also been improved; for example, centralised units for multiple installations with built-in redundancy are now available.
“The new version of the Wärtsilä NOx Reducer is designed for installation onboard newbuild vessels, as well as for retrofitting to existing ships. It not only enables compliance with existing and future legislation, but maximises the overall environmental performance and profile of the vessel, giving the change to profit from possible subsidizing bodies supportive emission reduction schemes. The upgraded design is in response to customer needs in the areas of installation flexibility, easy operation and maintenance, minimizing the impact on ship design while maintaining full flexibility on fuel selection,” says Giulio Tirelli, Director, 4-stroke Portfolio & Applications, Wärtsilä Ship Power.
The Wärtsilä NOR enables vessels to meet the International Maritime Organisation’s (IMO) Tier III NOx emission regulations, thus allowing them to operate freely within the current and planned Emission Control Areas (ECAs) designated by the IMO. Furthermore, Wärtsilä can optimise and deliver the engine and SCR as a fully tested, single package together with a Statement of Compliance for the IMO’s Tier III regulations.
At the Marine Environment Protection Committee (MEPC) 66 meeting in early April the IMO decided to maintain 1.1.2016 as the implementation date for the IMO Tier III NOx emission limits within the existing NOx Emissions Control Areas (NECAS). It was also decided to keep the implementation date flexible for future NECAS. This decision is based on the adoption date of a new NECA or, alternatively, agreement regarding later implementation dates during the designation process.
