Mitsubishi Shipbuilding a member of Mitsubishi Heavy Industries, Ltd. (MHI) Group, based in Yokohama, has increased production capacity for its SOx scrubber system that reduces SOx from the exhaust gas of ships, and has begun shipments of the DIA-SOx C Series tower and DIA-SOx R Series tower from partner fabricators in China and Taiwan, respectively.

The cylindrical C Series has been jointly developed with Mitsubishi Kakoki Kaisha and the rectangular R Series with Mitsubishi Hitachi Power Systems. Both series utilise a multi-stream configuration that can treat exhaust gas from multiple engines simultaneously.


The fabricator in China that manufactured the C Series tower has a track record of supplying high quality, reliable products for MHI Group, and has increased its capacity to be able to respond to the clients' requests for short delivery times and multiple slots. The Taiwanese fabricator that manufactured the R Series tower is a long-standing business partner of MHPS and has an outstanding quality management system. Mitsubishi Shipbuilding has received more than 50 orders to date for jointly developed systems (including both the C Series and R Series). For 18 of the ships among them, Mitsubishi Shipbuilding also provides engineering services for installation of the scrubber.

With new SOx emissions regulations coming into effect across the globe in 2020, Mitsubishi Shipbuilding has been receiving a steady stream of inquiries from customers worldwide and has responded to various demands with expanding production capacity including those two partner fabricators.
