Japanese shipping group NYK Line will retrofit 89 of its ships with a ballast water management system developed by Sunrui Marine Environment Engineering, a unit of Chinese state-owned shipbuilding group China Shipbuilding Industry Corporation.
The number of ships involved makes this the single largest order for ballast water management systems received by any manufacturer.
Sunrui announced that earlier this month, its general manager, Fu Hongtian, had signed the sales contract with NYK’s president, Tadaaki Naito, at a ceremony in the Japanese shipping line’s office in Tokyo.
The ships to be retrofitted include very large crude carriers, large bulk carriers, post-Panamax container ships, and chemical or product tankers.
According to NYK’s website, the shipping line has 755 ships across many segments.
Sunrui said retrofitting 89 of NYK’s ships was a continuation of a business relationship that began in 2013, when both began working on the Japanese company’s newbuildings and retrofitting existing vessels.
Based in Qingdao in Shandong province, Sunrui developed the BalClor ballast water management system, which treats water through filtration, electro-chlorination, and neutralisation. The system has won approval from the International Maritime Organization and the US Coast Guard.
The Ballast Water Management Convention went into force in September 2017 and requires newbuildings to be fitted with ballast water management systems from that date, while existing vessels will have to be retrofitted with such systems in order to have their International Oil Pollution Prevention certificate renewed after September 2019.
On 18 July, French liner operator CMA CGM said it had ordered ballast water management systems from compatriot manufacturer BIO-UV for 17 ships, including nine 22,000 teu vessels under construction in China.
