WR Systems of the US says that it has been asked to supply its Emsys laser-based emissions monitoring system for the purpose of emission verification for fuel trials on-board the AP Moller-Maersk vessel ‘Maersk Kalmar’, Motorship reports.
WR Systems is providing the system installation as part of a wider project between Maersk Line and the US Navy to test biofuels for their long-term suitability for maritime applications. Emsys was requested by Maersk following successful trial installations on two US-based Maersk container vessels. Previous trials were used to prove system efficacy and aid marine type approvals under the supervision of ABS.
The Emsys system will collect comprehensive emissions and PM data. This information will be included in a comprehensive performance report to be prepared by Maersk and audited by Lloyds Register. Data collected will include NOx, SOx, CO2 and PM. Additionally the report will detail findings on the effects of biofuels on the engine’s fuel system performance and normal wear and tear.
The Emsys system uses quantum cascade laser (QCL) technology, which WR Systems claims provides high accuracy, stability, and is suitable for the harsh environment experienced in the vessel’s upper funnel space. PM measurement takes place outside the stack, which allows a single optic to measure multiple stacks. The system is designed to be virtually maintenance free, so the maker claims the lowest cost of ownership of any available EMS system. The system carries full type approval from ABS for MARPOL Annex VI NOx and SOx regulations. It has been tested and type approved for the measurement of PM, mass emissions, and the CO2 operational index, as detailed in IMO Circular MEPC 471.
