REMOVING CHLORIDE

Quality standards of bulk chemical cargoes have increased dramatically over the past 5 years. It is reflected in the increasingly demanding inspection, loading and unloading quality control specification. In line with the above some of our charterers require more strict wall wash standard requirement,e.g:
1. Nil hydro carbon
2. Max 0.2 ppm of chloride
3. Pass visual inspection of all lines and connection
4. Suspended matter 12-16 spec

As we can see on the above chloride requirement, 0.2 ppm. It has increased from the previous requirement, 2-5 ppm. It is not so easy to achieve such a very low limit of chloride but of course it is achievable. Recently we have experienced many wwt failed due to chloride. Having a lot discussion with experienced Supercargo / Inspector and also some our chief officer. All agred that to meet above wall wash standard vessel has to conduct more intensive, effective, timely and proper tank cleaning.
