Ship Stability Video 38 - To find Upthrust & Position of Rock for a Vessel Grounded on Pinnacle
It is very important to apply the knowledge that we acquire in practice. In the process of grounding the change of draft occurs at various points along the ship. It must however be understood as caused due two independent phenomena viz.: trim change alone; and bodily rise or bodily sinkage alone. This is also the secret of resolving the complex grounding cases. In this video, a case of pinnacle grounding is discussed by Capt. S.S. Chaudhari. The knowledge will also be useful in determining the thrust on hull. The precise position of pinnacle and the tidal rise required to refloat the vessel can also be determined by a simple calculation.
