Bilge suctions ;

The bilge suction line in the hold bilge is normally fitted with a perforated strum box which prevents cargo debris from entering the bilge line.

The strum box should be thoroughly cleaned after each cargo discharge and if possible, dismantled and checked for damage or corrosion. The end of the bilge suction line must be confirmed as clear, with no debris fouling the end of the suction pipe.

To remove residue of previous cargo/ debris

To clean the mud & other rust accumulated

To get rid of foul smell & stench

Bilge suction must be tried out of efficient  working; & this is possible when the cargo hold is empty

Bilge is the potential source of cargo contamination.
