ALLEGRO: 5 Key Maritime Logistics Trends in 2019

As the industry leverages the latest technologies for growth, some things have changed to cloud the outlook ahead. Carriers have begun to behave differently because of varied changes in external market factors like geo-political climates and trade inbalances, and internal factors such as data duplication, lack of collaboration and the inability to optimize resources. CyberLogitec sees 5 dominant trends this 2019 that we believe will bring clarity in shaping the way forward.

World IT Show review (2) – Operating Eco-Friendly Ships: IT-Related SCR System Designed to Reduce Engine Exhaust from Ships

In general, large ships use a lot of oil. This means that they cause serious environmental pollution. And what accounts for a considerable portion of the pollutants is NOx. They are introducing an ever tighter emission limit on NOx, and starting in 2016, International Maritime Organizatio (IMO) will adopt a drastically strengthened regulation for NOx. Moreover, we need to brace up for expansion of ECA (Emission Control Areas). As there exists a study that has developed a way to improve on the matters, we’d like to share it with you.

NOx is quite common, as it is included in automobile exhaust. When it comes to ships, however, it’s a totally different story. For NOx discharged from ships is no to be compared in quantity to the gas emitted from automobiles. Increasing efforts are put in addressing such environmental questions, and the spotlight lately given on green IT ships is getting related research in full gear. Thus, people have embarked on initiatives to upgrade to eco-friendly and green ships.

The research team got their hint from the fact that NOx decomposes when it reacts with “AdBlue” urea solution, that is, ammonia. Consequently, the researchers came to think that they could develop a filtering system which would decompose NOx. And they named it SCR (Selective Catalytic Reduction) system and a reaction mechanism.

The research team applied solution polymerization and thereby succeeded in synthesizing WO3 powder with nanoparticles designed for NOx gas sensor. The powder is attached to the sensor to detect NOx, and the sensor automatically sprays “AdBlue” urea solution (ammonia) to the ceramic filter. When this filtering system is installed in the exhaust outlet, the discharged NOx automatically converts to nitrogen and water as it goes through the filter.

Currently, ceramic filter and nano powder have been developed. And by working further on the project, they aim to create a total system that will include detection sensor, control, and injector.

The process is as follows. The generated NOx passes through the filter, which has been developed with the team’s technology. Here, spraying WO3 powder will select NOx out. And ammonia meets the NOx to decompose it into nitrogen and water. Once the method is adopted, it will significantly reduce the amount of NOx that is discharged out of ships.

Countries of the world are expected to enforce ever tighter regulations on environmental pollution, and in response, various pollutant reduction technologies and processes will be developed. And, as addressed in one of our earlier articles, they are also trying to use new materials in lightening ships and thereby reducing pollutants generated in the ships. We expect that such eco-friendly technologies designed to reduce pollutants or improve ship efficiency will come along, not only with shipyards and ship-related technology firms, but also through technology development and reorganization of fleet operating strategy by shipping companies.
