Ship Cargo calibration is a method of determining the cargo tank volume accurately in order to determine the exact cargo or products whether in liquid or solid form. Cargo Calibration is the process of collecting cargo tank measurements and calculating accurate tank capacity based on these cargo tank calibration measurements. Sounding is the depth of liquid in a tank measured from the liquid surface to some reference point at the bottom of the tank . As a part of cargo tank calibrations, ship may require sounding table or ullage survey reports for loading/discharging the products.
Sounding table or trip capacity table in cargo ships can calculate by EIWAAs advanced tank gauging system software by our experienced naval architects/Marine Engineers. Final calibration tables in ullage and image (sounding) are made along with correction for ship list and Trim which is very essential when ship is not on an even keel.
Ship Tank Calibration
Two types of sounding methods are automatic and manual sounding surveys. Manual sounding is measuring the depth of tank by inserting sounding tape in the sounding pipe and lower the bob until it touches in bottom.
Ships and Vessel cargo tank calibration as per sounding/ullage booklet basis different increment level and trim will be the part of the deliverable. Cargo tank ullage report is detailed analysis of each cargo tanks ullage, Correction/ullage, Trim Correction Temperature, Exp. coefficient, Correction volume, Volume correction factor, tank sounding trim correction, Weight correction factor, Volume@15°C, Density @15°C after discharging as well as before discharging.
