More ports allow use of open-loop scrubbers
The Clean Shipping Alliance (CSA) 2020 has received written approvals and no-objection letters from more than 20 ports covering Europe, the Americas, Asia and Australasia, indicating they have no intention of banning the use of open-loop scrubbers in their waters.
Members of the CSA 2020 executive committee submitted to the ports scientific evidence concluding that the wastewater generated by the exhaust gas cleaning process was environmentally acceptable and well within regulatory limits.
In February, DNV GL verified a three-year study based on 281 wash water samples from 53 different EGCS-equipped vessels, concluding that the samples were well within the allowable IMO criteria, as well as within the limits of other major water standards. (kd)
