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 waterplane 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.
