Corrosion of distance piece on SOx scrubber discharge water line

Recently, ClassNK has received several reports for incidents that sea water leakage was detected from distance piece attached to hull on SOx scrubber discharge water line. The report concerns vessels classed with NKK (=ClassNK) but the design and possible problems are similar for all vessel with scrubber installations.

Until now, the leakages were detected at an early stage and did not cause heavy water ingress into E/R.

However, ClassNK has concerns that similar incidents would occur in the future for the other vessels as well and may cause more serious accidents such as a large amount of leakage and water ingress into E/R, thus providing this Technical Information.
