W R Systems Ltd., Norfolk Va. Announced the completion of its Emsys Product Design Assessment (PDA) program with the American Bureau of Shipping (ABS) by being awarded formal Type Approval on September 1st 2010.
The company said Emsys is the world’s first Quantum Cascade Laser (QCL) based emissions monitoring system to receive Type Approval for on-board verification of marine diesel engines and Exhaust Gas Cleaning Systems (EGCS) in line with the Revised MARPOL Annex VI and the NOx Technical Code (2008). The approvals cover both NOx and SOx emissions and additionally, Particulate Matter (PM).
The system was formally launched at the SMM 2010 Exhibition in Hamburg to complete the commercial development phase of the project which commenced in early 2009.
Emsys is unique in its design by incorporating 2nd generation laser based emissions sensing technology, combined with an ‘outside the stack’ PM sensor (Patent applied for). The system can sample multiple stacks and provide real-time and historical emissions reporting.
In addition to the MARPOL based Approvals, Emsys becomes the first system to be certified for the calculation of totalized emissions, Particulate Matter measurement and the calculation of the CO2 Operational Index in line with IMO Guidelines.
The integral PM sensor allows reporting of particulate matter in various formats to provide compliance data for forthcoming emission control areas and other localized regulations. The system utilizes a single PM sensor to measure specific emissions in g/kWh and mg/m3, removing the need for installation of sensors in each stack and eliminating the maintenance and cleaning requirements normally associated with this technology.
The Emsys system has been designed to meet the requirements of all current and future marine emissions regulations. A further enhancement to include Ammonia Slip (NH3) measurement within Selective Catalytic Reductions Systems (SCR) is planned for release subject to the finalisation of IMO Guidelines in early 2011.
