CR Ocean Engineering, L.L.C. (CROE) has recently been awarded the design and supply of two Open Loop exhaust gas cleaning systems (scrubbing systems) from STENA RoRo AB. 

The two systems will be installed to reduce SO2 from two main engines aboard the STENA Forefunner. The Stena Forerunner operates primarily in the European ECA where new low sulphur fuel regulations went into effect on January 1, 2015.  The CROE scrubbing systems aboard the Forerunner are scheduled to be on line in the first half of 2015.  Once installed, the scrubbers will allow the vessel to meet the low sulphur ECA requirements even when burning high sulphur heavy oil.  

The CROE Systems reduce the SO2 content of engine flue gas to below that found in 0.1% Sulphur fuel (the equivalency standard) even when burning high sulphur fuels.  Effective 1 January 2015, all ships that operate in the North American and European ECAs will be required to switch to the 01% sulphur fuel or install scrubbers to meet the equivalency standard for SO2.  This advanced CROE scrubbing technology can be used on new ships (newbuilds) or as a retrofit to existing ships.  The system is available in three standard configurations, customizable to the ship’s needs: a) as a once through scrubber [also known and Open Loop]; b) as a recirculating scrubber [also known as Closed Loop], and c) as a combination of both designs [also known as Hybrid].  

The system is designed to replace the existing silencers and does not require a bypass.  Its small size minimizes ship modification and makes this technology an excellent choice for cruise ships, ferries, bulk carriers, containerships, RoRo and others.
