Following last year’s analysis of the retrofitting of ballast systems status on its registered vessels, Japan-based ClassNK has confirmed that installation deadlines based on the Ballast Water Management Convention (BWM Convention) for many of them were highly concentrated in the year 2022.

The status has now been updated based on the latest data and the Society has confirmed that installation deadlines for many of its registered ships are still concentrated in the year 2022.

As of the end of August 2019, 7,124 of the 9,097 ships registered with ClassNK must install BWMS in accordance with the BWM Convention. Of this amount, 2,606 ships have completed the installation, leaving 4,518 ships that still require attention. Although the number of ships without BWMS has decreased by 882 within one year, the installation deadline for these ships remains largely concentrated in 2022.

Extensions to the original deadline were announced by the IMO in 2017. That allowed ships to delay installation until the next renewal date of their IOPP certificate after 7 September 2019. Since IOPP certificates have a validity of five years, the final installation deadline by which all ships must have a system installed is 7 September 2024

As difficulties are expected in the installation of BWMS if everyone around the world waits until 2022, ClassNK recommends installing well in advance.
