SCR system for marine engines - Complies with Tier III NOx emission standards -

Nitrogen oxide (NOx) is a major atmospheric pollutant and as such is subject to strict emission standards. NOx emissions from marine vessels are regulated by the International Maritime Organization (IMO). Hitachi Zosen has developed a diesel marine engine featuring SCR system that complies with the IMO regulations. The engine is the first with an SCR to be commissioned on an actual vessel, having been adopted by Nissho Shipping Co., Ltd.

In conjunction with Nissho Shipping Co., Ltd, Hitachi Zosen will conduct testing in open waters and port areas to assess overall system reliability and catalyst integrity during extended usage.
Joint development with MAN Diesel & Turbo
Hitachi Zosen is involved in an SCR system for marine engines joint development project with licenser of diesel engines MAN Diesel & Turbo to produce safe and optimized SCR systems.
