Japan’s ClassNK has advised shipowners to install Ballast Water Management Systems (BWMS) “well in advance” of 2022, which is the installation deadline based on the BWMS Convention for many of its registered ships.

“As difficulties are expected in the installation of BWMS if everyone around the world waits until 2022, ClassNK recommends installing well in advance. In addition, plan approval applications are also expected to concentrate during this period, therefore early application is strongly recommended,” ClassNK stated.

As of the end of November 2020, 7,220 of the 9,159 ships registered with ClassNK are obligated to install BWMS in accordance with the BWM Convention. Among these, 3,982 ships have completed the installation, leaving 3,238 ships that still require attention.

Although the number of ships without BWMS has decreased by 1,280 since August 2019, the installation deadline for these ships remains largely concentrated in 2022, according to ClassNK.

ClassNK said it has been following the retrofitting status of BWMS on its registered ships since 2018.
