Society ClassNK strongly recommends owners and operators do not leave the retrofit of ballast water management systems (BWMS) to the last minute. Its analysis shows an uncomfortable number of retrofit installations are due in 2022

As of the end of November 2020, 7,220 of the 9,159 ships registered with ClassNK are obligated to install ballast water treatment systems in accordance with the Ballast Water Management (BWM) Convention.

Among these, 3,982 ships have completed the installation of ballast water treatment systems, leaving 3,238 ships that still require BWMS to be installed.

Although the number of ships without ballast water treatment systems has decreased by 1,280 since August 2019, the installation deadline for these ships remains largely concentrated in 2022.

The latest information related to the BWM Convention and other technical information will be provided through the ClassNK website, with the latest information of the distribution of BWMS installation dates for Class NK existing ships.

As difficulties are expected in the installation of ballast water treatment systems if owners around the world wait until 2022, ClassNK recommends installing them well in advance.

In addition, plan approval applications are also expected to concentrate during this period, therefore early application is strongly recommended.
