Assuming the shape of the individual cargo tanks is fairly regular / constant in a fore and aft direction and, notwithstanding the fact that the vessel will be significantly trimmed by the stern, then the four measurements, as suggested in the COW Manual guidelines, as obtained by sounding can be used to calculate an average sounding so as to obtain a single sounding. See table above. as per surveyors calculation. Direct Application using the Correction Value. Assumption: Given the small angle involved with the trim of the vessel, then the Sine of an angle can be considered as the same as the Tangent (Tan) of an angle and consequently: Correct the position of the sounding position with respect to the aft bulkhead of the cargo tank due to the trim of the vessel, distance =. 0000002111 00000 n <>>> When you see a result like this, before you use the actual value of the balance, use the correction value, which is now the correction factor that will compensate for the error. Have you encountered the following scenario? Or, how to adjust the correction factor in order to have the exact value you need?
