The basic philosophy of the present Code is to apply standards contained in the Code and the International Code for the Construction and Equipment of Ships Carrying Dangerous Chemicals in Bulk (IBC Code) and in the International Code for the Construction and Equipment of Ships Carrying Liquefied Gases in Bulk (IGC Code) to the extent that is practicable and reasonable taking into account the unique design features and service characteristics of OSVs ER -
