MHI BOXSHIP SCRUBBER RETROFITS GAIN FLAG STATE APPROVALS

Thursday, February 6, 2020 

DIA-SOx R series, the marine SOx scrubbers produced by Mitsubishi Shipbuilding, a member of Mitsubishi Heavy Industries (MHI) Group, has recently been certified to conform to IMO 2020 SOx emissions regulations.

The first two examples of the scrubber were retrofitted onboard ultra-large container ships, and obtained approvals from the classification societies Lloyd's Register (LR) and Nippon Kaiji Kyokai (ClassNK), respectively after confirmation of sea trial results. Consequently approval has been given by the respective Flag States, Panama and Singapore.

The DIA-SOx R series, which has been installed onboard 20,000 TEU and 14,000 TEU container ships, was jointly developed by Mitsubishi Shipbuilding and Mitsubishi Hitachi Power Systems (MHPS). Its rectangular tower design is considered the most suitable for ultra-large container ships, and its multi-stream configuration can simultaneously treat, in a single tower, exhaust gas discharge from multiple engines, including the large main engine with output over 75,000kW. Moreover, its simplified configuration allows ease of maintenance.

Mitsubishi Shipbuilding and MHPS jointly dispatched two professional teams in parallel to a repair yard located in Zhoushan, China, and completed the commissioning work on the two vessels in five days, which is shorter than originally planned, through collaboration with the ship owners, the yard and the classification societies despite the congested site condition.

Mitsubishi Shipbuilding says it will continue not only providing marine scrubbers, but also act as an engineering company for scrubber installation to fully meet customers' needs and requests, regardless whether for retrofittings or newbuildings, for ships built by MHI or others, in order to contribute to reducing global environment impact.
