Verification of the calculation results
According to classification societies the check of correct working of the software on board is essential for the vessel's safety. Therefore, these societies have rules and guidelines for periodical testing of the loading and stability software. These guidelines can also be found in, amongst others, “IMO — Maritime Safety Committee (MSC) Circ.1108”, “IACS S1 Requirements for Loading Conditions, Loading Manuals and Loading Instruments” and “EBIS questionnaire edition 8”.
