Copenaghen - China and South Korea have agreed on exemption of ballast water exchange requirements for International ships sailing between People’s Republic of China and the Republic of Korea (South Korea).
The exemption runs from 1 June 2019 to 7 September 2024 and, as reminded by the Baltic and International Maritime Council, Bimco, this exemption is not applicable to ships which are required to meet the D-2 standards of the BWM convention as per regulation B-3. Therefore, if a ship is required to have an operational ballast water treatment plant, it should continue to treat its ballast water as per the D-2 standard.
Taking into account the difficulties found in conducting a safe and efficient ballast water exchange in the waters between China and South Korea, the maritime safety administration of China has issued a notice (Marine anti-pollution Decree  No. 661), exempting such ships from conducting ballast water exchange in accordance with Ballast water management (BWM) convention regulation B-4.1 and D-1.
