SHIP STABILITY 1
D78A 34
1. A ship has a length at the waterline of 56.2 m and breadth of 11.6 m and floats at a draught of 3.64 m in salt water.
(a) If the vessel’s displacement is 2096 tonnes calculate the block coefficient.
(0.862)
(b) Calculate the TPCSW of this vessel given that Cw is 0.822.
(5.493)
(c) How much more cargo may be loaded so that the ship sails with a draught of 3.96 m in salt water?
(175.8 t)
Use the hydrostatic particulars data sheet for the following examples
2. A ship arrives in port and has a draught of 5.20 m in salt water. How much cargo must be discharged so that the ship may sail with a draught of 4.60 m.
(1314 t)
3. A ship has an arrival draught of 4.90 m in dock water RD 1.006.
(a) What is the arrival displacement?
(9674.3 t)
(b) 2174 t of cargo is loaded. What will be the final draught of this ship when it enters salt water RD 1.025.
(5.800 m)
4. A ship displaces 10,516 t in salt water. 960 tonnes of cargo is loaded.
Calculate the final draught in salt water using:
(a) the displacement and draught scales only;
(5.633 m)
(b) the appropriate TPC value.
5. A ship has a draught of 6.00 m in dock water RD 1.004. How much cargo may the ship load to ensure that the maximum draught on sailing is 6.46 m in salt water.
(1292.7 t)
