Question 1:You have selected a (dumb) cargo barge for carrying a steel jacket module. Using the following specification guidance and instructions determine the maximum weight permitted for the module in order to ensure that the metacentric height (GM) on sailing is not less than 3.0m.SpecificationFor the jacket: Vertical Centre of Gravity (v.c.g.) = 12m above deck of barge.For a typical barge: Assume that the following are constant:Length = 100mBeam = 28mDepth = 8mBlock Coefficient = 1.0Maximum draught = 6.5mLightship Mass = 1900twith Vertical Centre of Gravity (vcg) 4m above its keeland v.c.g. of its water ballast 4m above keel.Guidance:When the calculation was done for a jacket weight of 8000 tones the metacentric height of the barge was found to be 2.440m.Instructions:Select another value for the weight of the module and calculate the resultant GM. Hence interpolate or plot a simple graph from which the maximum allowable weight of the jacket may be determined. (It is possible that only one calculation may be necessary since an accurate result is not required at this stage).
