Mitsubishi Heavy Industries, Ltd. (MHI) Group on Friday (4 September) said the DIA-SOx® series of its marine SOx scrubbers produced by Mitsubishi Shipbuilding Co Ltd has been successfully installed on 22 ships of three vessel types during the last 8 months from January 2020.
Despite the Covid-19 pandemic, Mitsubishi Shipbuilding said it successfully completed the installations as scheduled through remote commissioning conducted via close communication and cooperation with the engineers of its local partners in China and Singapore.
The line-up of DIA-SOx® consists of the R Series and C Series, it explained. The rectangular tower design of the R Series is the most suitable for container ships and its multi-stream configuration can simultaneously with 1 tower treat exhaust gas discharged from multiple engines, including the large main engine.
Moreover, its simplified configuration helps the ship crew to conduct the maintenance work easily. The C Series with cylindrical tower design also utilizes the multi-stream configuration, offering high flexibility that can be easily installed onboard various types of the ships.
Mitsubishi Shipbuilding added it also provides retrofit engineering for installation of both types of scrubbers, supporting customers to increase efficiency and improve reliability of their retrofitting projects.
For 14,000 TEU (Twenty-foot Equivalent Units) container ships for which Mitsubishi Shipbuilding provided engineering services not only scrubber systems, the scrubber tower was installed in the built-in casings on the port side of the existing funnel, and therefore the scrubber system was installed without reducing container loading capacity, which is one of the advantages of the rectangular tower shape of the R Series (see pictures).
Those systems, after their respective sea trials, obtained approval from Nippon Kaiji Kyokai (ClassNK), Lloyd’s Register (LR), American Bureau of Shipping (ABS), and other classification societies.
