First SCR NOx Removal System Installed on Coal Bulker
Aiming to Meet the IMO's Tier III NOx Emission Controls Nippon Yusen Kabushiki Kaisha, Oshima Shipbuilding Co. Ltd., Mitsubishi Heavy Industries Ltd., Akasaka Diesels Limited, and Sakai Chemical Industry Co., Ltd are to begin shipboard tests of selective catalytic reduction (SCR) nitrogen oxide (NOx) removal equipment installed on NYK Line's new bulk coal carrier Initial Salute, which was built by Oshima Shipbuilding. Shipboard trials of SCR NOx removal equipment were conducted during the voyage of Initial Salute. Once the equipment was verified to meet the tier III NOx emission controls stipulated by the International Maritime Organization (IMO),* it was decided to leave the equipment in place to collect more data through tests to be conducted during actual operational voyages.
MOL Marine Use Diesel Particulate Filter
Mitsui O.S.K. Lines, Ltd. announced the joint development with Akasaka Diesels Limited of a diesel particulate filter (DPF) for vessels that use marine heavy fuel oil. MOL reported that tests showed that the device removed more than 80% of particulate matter (PM) from diesel emissions. In the test, a DPF was installed on the main engine of an MOL Group-operated coastal ferry, the Sunflower Kogane. This test marked the first successful use of a self-regenerating DPF on a large vessel using marine heavy fuel oil. The Sunflower Kogane (9,710 gt, main engine: 9,267kw) is operated by The Diamond Ferry Co., Ltd., an MOL Group company. The DPF includes filters made of silicon carbide ceramic fibers, which remove PM from the exhaust.
