Loading /stress computer for chemical tankers
This instrument is provided to supplement the stability booklet for the vessel. It allows the Officer responsible, to carry out the various complex calculations required to ensure that the ship is not overstressed or damaged during the carriage of the nominated cargoes. It will also permit the assessment of damage stability. The Master and Chief Officer will make themselves aware of the worst case damage stability scenario condition within the stability booklet.
It must be remembered that a loading computer, as with navigation aids, is only an aid to the operator. It relies on human input of data, and more importantly the human interpretation of the output data. If the input data is incorrect, the output data will also be incorrect. Used correctly it will ensure the safe operation of the ship for all conditions of loading, discharging, ballasting and at all stages of the voyage.
It is a requirement that where such equipment is provided to a ship, test conditions must also be supplied for use in verifying the accuracy of the equipment. It is Company policy that test conditions must be run as soon as possible after a change of Chief Officer and at least every three months and prior to the vessel proceeding to dry-dock. Where the running of these test conditions reveals errors the Company is to be advised immediately with a request for attention.
Where online gauging of tank contents is not fitted, the loading computer must be regularly updated during cargo operations in order that stresses, draft and trim can be monitored throughout the operations. The damaged stability as per IBC code for each loading condition and discharging conditions to be complied with.
