Ship tank Calibration and Ullage Survey:

Ship Cargo tank Calibration:

Ship Cargo tank calibration in otherwise called Ullage survey 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 tank Calibration is the process of collecting cargo tank measurements and calculating accurate tank capacity based on these cargo tank calibration measurements.

Ullage Survey:

Ullage is a measurement of space between the surface of liquid in a cargo tank and the top of cargo tank inner surface. Ship’s ullage tables are drawn up, based on the internal volume of tank measured from some reference point; called lip of an ullage hole. By using advanced EODR(Electro Optical Distance Ranging Method)Measurements ,we can find out the ullage survey measurements in a cargo tank in order to prepare the ullage survey chart or dip chart as per the IACS regulations.

EIWAA  use the most accurate, reliable, and fastest laser measurement systems available. International Method followed: API MPMS 2.8.A Sounding pipes / gauge points are measured very accurately for ullage or sounding measurements table properties. Final calibration tables in ullage and innage (sounding) are made along with correction for ship list and Trim which is very essential when ship is not on an even keel. All data also provided electronically for Integration into ship software for radar / auto gauging. Our calibration tables are recognized by all IACS approved classification agencies

Sounding Table :

Reverse of Ullage is the sounding. 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.
