Full ban on open-loop scrubbers not yet imposed in China
In recent days, there has been reports that the Ministry of Transport in Beijing has now banned open-loop scrubbers from the country’s emission control areas (ECAs), which now cover most of China’s territorial waters, BIMCO says in press release.
Sources familiar with the matter have however told BIMCO that according to the updated regulation, the banned areas for discharging wastewater from scrubbers remain within inland ECAs, port waters under coastal DECA and the Bohai Bay waters only.
A full ban on open-loop scrubbers could however be adopted soon, sources familiar with the matter also told BIMCO.
In November, regulators said ships equipped with scrubbers were permitted to carry and use High Sulphur Fuel Oil (HSFO), subject to emissions monitoring, and that scrubber waste and water must be disposed according to relevant regulation. This remains the case.
In October, there was speculation that China was planning a ban on open loop scrubbers. Chinese officials confirmed to BIMCO at the time that there were no immediate plans to impose a ban on the technology, as long as they were in compliance with prevailing regulation.
The updated DECA regulation is designed to supplement the previous regulation, as well as to provide more detailed guidelines for implementation.
BIMCO members are encouraged to pay attention to the following points from the new DECA regulation:
Ships that need to switch to low sulphur fuel must make a fuel switch plan and keep it onboard. The switch timing, ships position, fuel sulphur content - before and after switching – as well as fuel tank data and consumption details must be properly recorded on the ship’s Engine Log. BIMCO reads this as in line with IMO requirements for entering and leaving ECAs in accordance with MARPOL Annex VI;
The discharge and disposal of water pollutants generated by ships using exhaust gas cleaning systems (scrubbers) must meet the requirements of relevant regulations. It is prohibited to discharge wastewater generated by open-loop scrubbers within the inland emission control areas, port water areas of coastal emission control areas and Bohai Bay water areas;
A yet to be decided ban on wastewater generated by open-loop scrubbers within the whole of China’s domestic emission control area will be announced in due course;
It is prohibited to discharge exhaust gas washwater residues into any current DECA water or burn them onboard.
