This video is really helpful for up coming chief officers. Kindly post one video taking into account different densities and hog/sag deflection. Thanks
Very helpful video. Sir, any particular reason as to why hog/sag allowance was applied only at the beginning, but not in the later part of the calculations? Thanks
Very nicely explained all stages for learning purpose. Is there any reason for not taking the extra cargo loadable due to consumption of fuel during the voyage? As the limiting draft restrictions is at arrival port gangavaram only.
yes. we do keep into account hog/sag allowance whenever we plan for cargo. in this example we have not taken this for the sake of simplicity. however we shall discuss the same in our upcoming videos.
Thank you for asking!. The sag allowance is taken mostly when you are loading up to marks OR loading upto maximum allowable draft. When we calculated maximum cargo that can be loaded at Aqaba we took the SAG allowance and came to conclusion that we can load maximum cargo of 81651 mt. However, later we calculated that maximum cargo that can be loaded without exceeding the limits is 69884 mt ONLY. So, if we load this cargo at Aqaba, we will not be exceeding the draft limitations anytime. Therefore, there was no point taking into account the SAG allowance at loadport. Even if SAG develops, the vessel under the influence of dynamic stresses, stretches itself out and normally mostly the SAG would be negligible at the end of a long voyage!. Hope it clears!
But sir if sag will occur than we will be exceeding the draft at gangavaram ,as we calculated the cargo at 13 mtrs 1.025 density, not taken sag allowance.
Good day Sir, can i also ask a copy of your calculations for limiting draft? Im also a aspiring Chief Officer, it help me alot, if you send me your program.. Thanks in advance.. For power and subscribers.
