Emissions monitoring added to enginei

Royston has upgraded its enginei fuel management system, adding a new emissions monitoring capability with an engine profile-based emissions analysis feature.

{mprestriction ids="1,2"}The new system can operate without the need for an exhaust gas analyser, capturing engine performance data, engine and fuel specifications, and flow rates which are then used for the calculation of a range of vessel emissions measurements.

NOx profiles for individual engines are created using the ‘carbon balance method’, with reference to the NOx Technical Code MEPC 177 (58), statistical algorithms and engine test data. Combining this with operational factors such as torque, RPM and other engine and fuel data enables a specific NOx emissions factor to be calculated for comparison with IMO regulations.

In addition, SOx and CO2 emissions are computed from the mass balance conversion factor applied to the adjusted fuel consumption and air mass flow, alongside combustion efficiency. This enables advisory SOx levels to be predicted, to inform fuel switch over decisions during travel in emissions controlled zones.

The upgraded enginei system also provides combustion efficiency data alongside the automatically generated emissions measurements, assessing engine power against both fuel consumption and engine speed, with comparisons of individual engine performance made based on specific fuel oil consumption measurements.

All fuel and emissions data collected can be automatically incorporated into daily reports in a range of formats. On board the vessel, touchscreen monitors on the bridge and in the engine control room show all aspects of key vessel performance criteria.

Supporting the new range of reporting and monitoring options, the enginei system is now equipped with 24/7 remote access, for the continuous monitoring and troubleshooting of vessel installed systems from shore.

This capability also enables data service upgrades and technical enhancements to be made from a central source.{/mprestriction}
