JAPAN's Mitsubishi Shipbuilding says its DIA-SOx marine scrubbers have been installed on 22 ships during the last eight months, reports New York's Marine Link.
The builder said the installations were completed as scheduled despite the continued spread of Covid-19 globally through remote commissioning conducted via close communication and cooperation with its local partners' engineers in China and Singapore.
The DIA-SOx lineup consists of the R Series and C Series. The rectangular tower design of the R Series is the most suitable for containerships, and its multi-stream configuration can simultaneously with one tower treat exhaust gas discharged from multiple engines, including the large main engine.
The C Series with cylindrical tower design also utilises the multi-stream configuration, offering high flexibility that can be easily installed onboard various types of the ships.
For 14,000-TEU ships 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.
The R Series has been installed on five 20,000-TEUers, eight 14,000 TEUers and five 10,000 TEUers or less.
The C Series has been fitted on two large oil tankers with dead-weight capacity of 300,000 tonnes and two liquefied petroleum gas (LPG) carriers.
These systems, after the verification by sea trials, received approval from Nippon Kaiji Kyokai (Class NK), Lloyd's Register (LR), American Bureau of Shipping (ABS), and other classification societies.
The French firm will charter all of the six sister vessels scheduled for delivery from Hyundai Samho by 2022.
