Question:

The report will be assessed against the accuracy and completeness of presenting the following data and answers:
1. Present in one figure how the displacement, block and prismatic coefficients change with respect to the draft. Are the observed changes sensible Explain why.
2. Plot GZ values with respect to the heel angle for two tested displacements (135000 and 145000 tonnes). Explain the difference between the two curves.
3. In the barge, when tanks 1 and 8 are partially filled with fresh water (80% and 10% respectively), does it create a positive or negative trimming moment Support your answer with a relevant simple sketch. Given the fact that the
tanks are not fully flooded, what other important effect will it have on the barge stability
4. When the barge’s tank 1 and 2 are fully flooded with water, calculate the trimming angle and forward and aft drafts and compare your results with Maxsurf.
