Huarun Dadong Dockyard Co., Ltd. (HRDD), a subsidiary of China State Shipbuilding Corporation (Hudong-Zhonghua Shipbuilding (Group) Co., Ltd, has successfully completed the world’s first Carbon Capture System (CCS) retrofitting project for a large containership”Ever Top”.
The containership “Ever Top” is a 152,300 dwt Panama-registered containership with a capacity of 18,000 TEU. The system that was installed uses amine absorbents to selectively capture and separate CO2 in the ship’s exhaust. It is then compressed and liquified for transportation, storage, or utilization in industrial applications.
The comprehensive carbon dioxide capture rate of the system reaches more than 80%, and the purity of resolved carbon dioxide reaches more than 99%, which fully meets the requirements of the medium- and long-term decarbonization strategy of the International Maritime Organization (IMO), and makes this large box ship with 10 years of age transform into a brand-new green, low-carbon and environmentally friendly ship.
The retrofitting project was extensive and included sub-projects such as segment fabrication, painting, outfitting and equipment installation, segment general assembly, and structural reinforcement. According to the project requirements, the desulphurization tower and carbon capture system had to be pre-installed into the pre-fabricated tower house segments.
It is reported that after more than 3 months, HRDD successfully completed this CCS retrofitting project. And on January 18, 2024, the refitted Ever Top was put back into service.
It is understood that the decarbonization system used in this refitting project is independently developed, designed and built by Shanghai QiYao Environmental Technology Co., Ltd., a leading company in the industry. The system involves a number of specialized technical fields, among which the advanced organic amine cycle adsorption technology, which utilizes the chemical adsorption between organic amine and carbon dioxide to separate carbon dioxide from the mixed gas emitted by the ship’s main engine, has a wide range of application value and market prospects.
