MariNOx Evolves With Emissions Requirements: Martek Marine introduces next-generation MariNox Evolution

More than five years ago, U.K.- based Martek Marine introduced the MariNOx diesel engine emissions monitoring system for marine applications. Now, with more than 100 installations and a few years later, Martek is offering the MariNOx Evolution, a second generation of the technology incorporating improvements and features to improve efficiency.

Martek Marine has introduced the MariNOx Evolution, the second generation of its diesel engine emissions monitoring system for marine applications. It is designed to measure NOx, SOx and CO2, in addition to CO, hydrocarbons, ammonia (for SCR systems) and smoke opacity to levels exceeding MARPOL regulations

Martek Marine has introduced the MariNOx Evolution, the second generation of its diesel engine emissions monitoring system for marine applications. It is designed to measure NOx, SOx and CO2, in addition to CO, hydrocarbons, ammonia (for SCR systems) and smoke opacity to levels exceeding MARPOL regulations

The MariNOx Evolution was developed to measure NOx, SOx and CO2, in addition to CO, hydrocarbons, ammonia (for SCR systems) and smoke opacity to levels exceeding MARPOL
regulations. The company said applications include LNG ships, tankers, cruise ships and car carriers for owners who wish to display high levels of environmental compliance.

The MariNOx Evolution has been redesigned from the first iteration of the system to incorporate a single, daisy-chain sample line, which replaces the previous arrangement that required several separate sample lines, said the company, and allows for easier installation. Martek said reducing the number of sample lines and cutting the amount of cabling onboard will take a significant amount of time out of the installation process. In addition, the power to heat the sample lines has also been reduced by the single sample line configuration.

Steve Coulson, Martek Marine’s marketing director, said, “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.” MariNOx Evolution also comes with DataLINK software, which 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 emissions. The latest software shipped with MariNOx Evolution incorporates the IMO’s new Energy Efficiency Design Index (EEDI) formula, further enhancing the accuracy of emissions-level recording and trend analysis, said the company.

The smoke opacity sensor is an option on the MariNOx Evolution to measure the density of the engine smoke. This can be useful when operating in areas of the world where fines are imposed for generating black smoke. By measuring density in 12-minute intervals, data is logged and calibrated should a fine be administered. Martek also added that by monitoring emissions, operators are able to fine-tune engines and see up to 4% fuel savings.
