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.
