Major changes with regards to cargo ventilation in the new OSV Chemical Code
A number of liquid cargoes has been reclassified in the IBC code and are now considered to pose a safety hazard as well as a pollution hazard. In A.673, there was a possibility of waiving some requirements for tanks carrying ”pollution-only” products. Some of these products are not “pollution-only” anymore. Methanol is now classified as toxic.A.673 limits the products to be carried to IMO Ship Type 3 products, which are non-toxic. Exeptions are made for the carriage of Methanol on exisiting vessel, certified in accordance with A.673. The same goes for other products that are now assessed as being outside of IMO Ship Type 3 products.
