Hitachi Zosen Receives Order for Marine Diesel Engine Equipped with SCR System -First for Ship Newly Built in Japan Compliant with Tier III NOx Emission Standards-

Hitachi Zosen Corporation has received an order from Sumitomo Heavy Industries Marine & Engineering Co., Ltd. (Shinagawa-ku, Tokyo; President and CEO Hideshi Shimamoto) for a marine diesel engine equipped with a selective catalytic reduction (SCR) system. This represents Hitachi Zosen’s first order for an engine with built-in SCR system as well as its first order from a Japanese shipyard, following an order for SCR systems only for Chinese and South Korean companies.

■Project outline
The engine equipped with the SCR system will be installed in an Aframax tanker owned by a European shipping enterprise to be produced at the Sumitomo Heavy Industries M&E Yokosuka Shipyard.
Hitachi Zosen is a licensee of MAN Diesel & Turbo SE (Germany), the world’s leading provider of marine engines, and the company’s SCR system globally the first to receive first-time approval (FTA) from MAN Diesel & Turbo. The latest order suggests that the system fully compliant with Tier III NOx emission standards was embraced by the environment-conscious shipyard and shipowner, and Hitachi Zosen plans to continue promoting its marine SCR system in future.

■Features of marine SCR system
The marine SCR system uses a catalyst to reduce NOx contained in the exhaust of diesel engines during operation. Hitachi Zosen is globally the only manufacturer of both marine diesel engines and catalysts, and through in-house production realizes an ideal balance between compactness of the system itself and of catalyst volume, and the performance of catalytic activation. The company offers high-pressure and low-pressure SCR systems for installation upstream and downstream of the turbocharger, respectively.

■Tier III NOx emission standards
The third level (tier) of controls set by the International Maritime Organization (IMO) requires an 80% reduction in NOx emissions from operating marine vessels compared to Tier I standards.
