Determining the height of the ship’s forward part on the seabed
and the reaction of the seabed 

Abstract: The article presents the experimentally calculated and verified height of the ship’s forward part on contact with the seabed. According to the height, the reaction of the seabed has been calculated as well. The height of the forward part of the ship is conditioned by the reaction of the seabed when the ship is moored at a wild shore. The force acting on the hull from the seabed is equal to the weight of the part of the vessel’s hull displacing the water. The shape of the landing ship mooring at a wild shore is of great significance, for it conditions the weight of its forward part which is above the water and the seabed. The maximum height of the forward part of the vessel is calculated by the kinetic and potential energy balance equation. The formulas presented in the paper enable one to calculate the reaction of the seabed according to the speed of the vessel as well as the stability and condition in the mooring area.
Key words: amphibious ship, self-propelled barge, contact, design pressure, hull load.
