Synopsis of the task and its context
Students individually develop a software package to calculate motion response spectrum using experimental data collected for 1:20 scale
model ship (Bluefin) at AMC towing tank. The model is operating in head sea at 1 m wave height at 8 knots (0.05 m @ 0.92m/s model scale).
This is using the constant wave height, varying wave freq data and then by adding the final three runs at varying wave height with constant
frequency. There is an Excel file attached to this assignment that provides the ship's particular and the experimental data. For model scaling
refer to the references.
1- Plot the required spectrum and RAO using variable input parameters collected at different experimental runs
2- Calculate the motion response parameters such as spectral moments, mean response period (frequency), significant response amplitude and
maximum amplitude in each of the given motions.
3- A review should be conducted in a form of a report to demonstrate the knowledge and understanding by discussing the linearity of the
seakeeping behaviour of Bluefin.
