MPA would like to draw up attention to the increase in Port State Control (PSC) detentions experienced by Singapore ships since the beginning of 2019. In particular, it has been noticed that defects relating to the ship’s sewage treatment plant are increasingly becoming a common deficiency that cause ships to be detained by PSC.

The sewage treatment plant (MARPOL Annex IV) deficiency was featured as the second most common detainable deficiency in the Tokyo MOU for Port State Control for the year 2018.
