Emissions monitoring moves forward
MariNOx Evolution
UK company Martek Marine says that its recently-launched MariNOx Evolution includes a number of new features designed to enhance efficiency.
MariNOx Evolution is the latest version of the MariNOx diesel engine emissions monitoring system and is based largely on the existing MariNOx technology, which has been successfully installed on over 100 vessels worldwide. The company says that installation and running of the new system has been substantially refined by the incorporation of a single, daisy-chain sample line design, replacing the previous arrangement which required several separate sample lines. Reducing the number of sample lines, and cutting the amount of cabling onboard, should save a significant amount of time and money. Furthermore the amount of power needed to heat the sample lines has been reduced through having the single sample line configuration.
MariNOx Evolution comes with more advanced DataLINK software that gives the user greater control over the emissions monitoring process. This allows for more accurate performance management of the diesel engines, thereby helping users further reduce operational costs and harmful emissions. The latest software makes use of the IMO Energy Efficiency Design Index (EEDI) formula to further enhance the accuracy of emissions level recording and trend analysis.
According to Steve Coulson, Martek Marine’s marketing director, “In avoiding the need for multiple, separate sample lines, MariNOx Evolution represents a significant step forward. This is a much simpler arrangement that will benefit customers and shipyards alike, by virtue of its less complex installation.”
As an optional extra, MariNOx Evolution can be configured to integrate opacity sensor input, measuring the density of engine smoke, directly into its control software. “This makes MariNOx Evolution unique in the market,” says Coulson, “and we believe this new feature will greatly assist shipowners in monitoring the performance of marine diesel engines in order to reduce environmental impact.”
The first order for MariNOx Evolution has recently been completed and other contracts have been confirmed. The system is now Martek marine’s standard emissions monitoring offer. The original MariNOx was the first type approved system for monitoring NOx, SOx and CO2 emissions, and is designed to help shipowners comply as easily as possible with Marpol Annex IV rules, as well as the NOx Technical Code and MEPC 103 (409).
