Abstract

Shipment of the segments and its stability while loading and unloading of cargo over the barge.The calculation of meta center and Meta centric radius makes the barge stable .3.6 tonnes per centimeter immersion increase one centimeter height of the drought .The dimensions of the barge and its displacement of total volume of water helped for calculation of overall mass of the barge .The flooded tank water inertia affects the meta center height of the loaded segment and barge loss its stability. The height if the cargo and maximum in range between 30 degree to 40 degree affects the hull structure.Center of buoyancy force which act in middle of the vessel or ship in upward vertical direction and the center of gravity which also act on the center of the vessel in downward direction this allow any vessel to float on the surface of the water is called as Archimedes principal .Meta center radius which help ship to float on water surface with stability — • Calculation of GZ curve to determine the stability of the barge at the working load and the safe working load chart.The meta center height of the loaded cargo on the ship.The flow rate and the wind intensity at 360 mm of rainfall in 24 hrs. • To prevent from the hull damage and collapse from the pier during the lifting operations.The preparation of risk assessment and the safe working process. • By using the hydraulic tool box software and GZ curve plotting to determine the stability of the barge. • If the rainfall intensity is 360 mm in 24 hours having the wing intensity of 30 m/s.The flow rate of the water is 35000 cubic meter per second then the lifting process is full of hazards. • When heeling angle is above the 30 degree then the both center of buoyancy and gravitational force shift to the port or to the star board .Then the vessel if load is shifted to port side then the both acting force will shift to the starboard and make the ship in the stable position. Flooding tank which is designed in the vessel make the ship in stable position and prevent to damage of hull. Load which is shifted on the vessel should be fixed some time it creates the twisting moment in ship and heeling angle reached to the point more than 30 degree and ship loss it stability vi A ship or vessel state to be in stable phase when both centre of buoyancy force and gravitational force meet at the centre of the vessel and the heeling angle should be in range of 7 degree to 8 degree .When heeling angle is above the 30 degree then the both centre of buoyancy and gravitational force shift to the port or to the star board .Then the vessel if load is shifted to port side then the both acting force will shift to the starboard and make the ship in the stable position. Flooding tank which is designed in the vessel make the ship in stable position and prevent to damage of hull. Load which is shifted on the vessel should be fixed some time it creates the twisting moment in ship and heeling angle reached to the point more than 30 degree and ship loss it stable
