The Draft and Load Calculator is used for continuous, quantitative determination of the dredged material. The system provides the operator with a quick and complete overview of the status of the ship (draught, trim, heel and hopper level), the operational data (displacement, load, solid) and the operation mode. The measured and calculated data are shown on a dedicated screen in a clear manner, displaying all relevant data.

With this system the operator can easily decide when the target load has been reached and is informed about his daily efficiency at all times. The reports generated by the system provide a comprehensive documentation of each job. The determination of the load condition of the ship is performed using the values measured by various sensors. The draught is measured by a selection of pressure sensors and the hopper level is measured by different ultrasonic sensors. Trim is calculated from the values provided by the draft sensors.  The ship's displacement and hopper volume are obtained from the tables stored in the loading computer using the draught, hopper level and trim values.  The dredged material without water content (dry) is calculated using the displacement and volume values obtained from these tables and the manual inputs of the seawater, in situ and dry density.
The measured and calculated data are shown on a dedicated screen in a clear manner, displaying all relevant data.

In addition reports can printed per trip, consisting of the most important data values and the loading/unloading diagram. The main trip data is also stored for later reporting and evaluation by third party systems using office tools such as Excel or Access.
