JANUARY 25, 2013 — Wärtsilä reports that it has received a repeat order to provide a hybrid exhaust gas cleaning and SCR system. The contract was signed in December 2012. Wärtsilä has not disclosed the name of the customer.
The systems provide universal compliance with sulfur limits including the North American ECA, the 2015 0.1 per cent ECA in Europe, the worldwide 0.5 percent sulfur limit from 2020 and Tier III IMO NOx limits from 2016.
The hybrid exhaust gas cleaning system also enables the choice between open-loop and closed-loop scrubbing to be made at any time, maximizing control.
This means that exhaust gas cleaning using only seawater can be enabled at sea but while maneuvering or in port the system can be closed, re-circulating the water already within the scrubber. In addition, the SCR system, which is integrated into the engine downstream of the exhaust gas turbine, will remove up to 95 percent of NOx from the vessel's emissions.
Sigurd Jenssen, Director, Exhaust Gas Cleaning, Wärtsilä Ship Power, Environmental Solutions, says: "This repeat order, included in the 2012 fourth quarter order book for Wärtsilä, further validates scrubbing technology as a proven, efficient and cost effective method of meeting and exceeding ECA compliance and is evidence of the strong customer partnerships that we develop and the quality of the systems that we provide. Wärtsilä customers are at the forefront of proactive preparation for further incoming environmental regulation and are taking their responsibilities seriously."
