Virginia-based firm successfully com- pletes Product Design Assessment (PDA) program with the American Bu- reau of Shipping (ABS) and is awarded formal Type Approval on

September 1, 2010. — by Joseph Keefe

September’s Shipbuilding, Machinery and Marine (SMM 2010) trade fair in

Hamburg, Germany provided WRSys- tems (www.wrsystems.com) with the ideal platform to launch the Emsys Ma- rine Emissions Monitoring System to the global shipping industry. Days after the announcement of ABS Type Approval,

W R Systems Senior VP Dave Edwards led potential distributors and technology partners through details of how the new combined Laser and Particulate Matter (PM) measurement technology will work.

Emsys is the world’s first Quantum

Cascade Laser (QCL) based emissions monitoring system to receive Type Ap- proval for on-board verification of ma- rine diesel engines and Exhaust Gas

Cleaning Systems (EGCS) in line with the Revised MARPOL Annex VI and the

NOx Technical Code (2008). The ap- provals cover both NOx and SOx emis- sions and additionally, Particulate Matter (PM). The ABS type approval ends the firm’s commercial development phase of the project, which commenced in early 2009.

Simon Brown, W R Systems’ Director of International Marine Business, added, “The technology incorporated in the sys- tem is a significant leap forward over the systems currently available. Emsys will set new standards in emissions reporting, and can be of significant financial bene- fit if incorporated within vessel compli- ance management and operational efficiency programs.” Ship’s personnel, for example, can adjust a myriad of en- gine inputs to provide for a cleaner and more efficient burn, based on data re- ceived from the Emsys monitoring equip- ment.

The Emsys design incorporates second generation laser based emissions sensing technology, combined with an ‘outside the stack’ PM sensor (Patent applied for).

Notably, the system can sample multiple stacks while providing real-time and his- torical emissions reporting. In addition to

MARPOL based Approvals, Emsys be- comes the first system to be certified for the calculation of totalized emissions,

Particulate Matter measurement and the

CO2 Operational Index in line with IMO

Guidelines.

With emissions reporting becoming commonplace within schemes such as

TMSA (operated by OCIMF), the Emsys system is the only technology available to provide a full emissions inventory for

NOx, SOx and CO2 for all installed en- gines and boilers. The sophisticated soft- ware suite incorporates GPS position and time stamping to allow highly accurate report generation. Additionally, the auto- mated CO2 Operational Index Software module can simplify data collection and index generation, while increasing the ac- curacy of reported data.

The integral PM sensor allows report- ing of Particulate matter in various for- mats to provide compliance data for forthcoming Emission Control Areas (ECA). 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 associ- ated with this technology. Designed to meet the requirements of all current and future marine emissions regulations, fur- ther enhancements also include Ammo- nia Slip (NH3) measurement within

Selective Catalytic Reductions Systems (SCR), planned for release subject to the finalization of IMO Guidelines in early 2011. www.wrsystems.com
