Royston Adds Emissions Monitoring to Enginei Fuel Management System

Royston has upgraded its enginei fuel management system.

Royston Wednesday announced that it has upgraded its enginei fuel management system with the addition of a new low cost emissions monitoring capability.

The new system, which does not require an exhaust gas analyser, is said to capture key engine performance data, engine and fuel specifications, and flow rates to provide an accurate calculation of a variety of vessel emissions measurements.

Royston explains that the system creates NOx profiles for individual engines using the "carbon balance method," combined with operational factors, including torque, RPM, and other engine and fuel data to calculate a specific NOx emissions factor for comparison with International Maritime Organization (IMO) regulations.

Meanwhile, SOx and CO2 emissions are calculated from the mass balance conversion factor applied to the adjusted fuel consumption and air mass flow, in conjuction with combustion efficiency, to allow for advisory SOx levels to be predicted and inform fuel switch over decisions during transition to and from emissions control areas (ECAs).

"Enginei systems are now installed in vessels of all types operating across the globe, helping vessel owners and charterers to meet high standards of operational performance and efficient fuel consumption," said Damian McCann, product manager for fuel management systems at Royston.

"The new engine-profile based system builds on this capability by using all the available engine performance data to enable operators to continuously and accurately measure important vessel emissions and report on the findings."

Royston says the upgraded enginei system also provides combustion efficiency data, in order to assess engine power compared to fuel consumption and engine speed, as well as comparisons of individual engine performance based on specific fuel oil consumption measurements.

Fuel and emissions data collected by the system can be automatically incorporated into daily reports in a range of formats, with information captured onboard can be made available for remote analysis by onshore personnel through a secure online portal, explains Royston.

"With maritime emissions monitoring becoming a critical factor for vessel operators, the new system provides a highly cost effective and accurate method to demonstrate environmental responsibility and compliance with the ever stringent industry regulations," concluded McCann.

In August, Royston announced the introduction of a new engine diagnostic, health check, and consultancy service that it says supports vessel fuel savings and emissions reductions.
