Q16. A ship floats at a draught of 10 m in sea water of density 1025 kg/m3. In this condition the center of gravity is 10.396 m above the keel and the second moment of area of the waterplane about the centerline is 110000 m4. Values of tonne per centimeter immersion (TPC) in sea water are given in Table Ql.
A load is to be discharged from the ship’s centerline by the ship’s own heavy lift crane. The crane head is 15 m above the original center of gravity of the load and 18 m from the ship’s centerline when swung out. During the discharge, it is required that the metacentric height should not be less than 1.75 m.
Determine ËACH of the following:
(a) The maximum load the crane may lift;
(b) The angle to which the ship will heel when discharging the maximum load.
