1. (10%) A ship of length 180 m and beam 20 m floats at a mean draught of 8.5 m when in water of density 1.025 tonnes/m3. Assuming her block coefficient is 0.5 and her water plane coefficient of fineness is 0.6, calculate the ship’s displacement and her approximate draught when it enters water of density 1.010 tonnes/m3.
2. (10%) A ship of 8,000 tonnes floats at a draught of 7 m with a freeboard of 4 m. A uniform weight of 65 tonnes on the deck is 4 m high and it is to be lifted by a crane with its -suspension point 12 m above the deck. If the original KB = 4.25 m, KG = 6.75 m and KM = 7.65 m, find the reduction in GM when the crane lifts the weight from the deck.
3. (15%) What do you understand by the terms “hogging” and “sagging” in relation to longitudinal strength? Explain how you would go about finding the longitudinal bending moment amidships of a ship:
1. In still water.
2. In waves using a standard wave of length equal to that of the ship.
4. (25%) Describe five types of structural defects on cargo ships and explain why each of these failure mechanisms may occur.
5. (20%) Outline what is mean by “the tort of negligence” and give an example of how it may apply in:
1. Commercial shipping
2. You, as a surveyor
6. (20%) A claimant can sue for damages for both breach of contract and tort of negligence. Explain how the measure of damages applies in each case under English law.
