As of the end of August 2018, there are 7,315 ships on the ClassNK register that have to install BWMS in compliance with the BWM Convention. Of these ships, 1,915 have completed the installation, leaving 5,400 ships that still require attention.

 

The distribution of BWMS installation deadlines in line with the BWM Convention is as follows: 92 ships by 2019, 662 ships by 2020, 795 ships by 2021, 2,832 ships by 2022, 558 ships by 2023, and 461 ships by 2024, with the majority being highly concentrated in 2022. The peak figure for 2022 may decrease due to the influence of ship recycling trends and response to USCG regulations.
