• Compare and contrast dimensional analysis and theory and numerical and experimental results.

Learning Outcomes

Having successfully completed this module you will be able to:

• C1/M1 As a part of the group assessment, students must apply a comprehensive knowledge of mathematics, physics, and the principles of naval architecture to solve the potential flow theory numerically to find the potential coefficients of a ship section. C2/M2 In the seakeeping assessment, students must analyse the ship motions in regular and irregular seas in various operational conditions to make a judgement about the operability of the ship in question while also discussing the limitations of the potential flow theory used in the calculations. C3/M3 As part of the group assessment, students are required to apply computational techniques to model the complex problem fluid-structure problem around a ship section with a view to calculating 2-D added mass and damping coefficients in waves while also discussing the associated theory's limitations. C4/M4 In the seakeeping assessment, students must critically evaluate technical literature and other sources of information, such as project reports or articles in this field. They will apply a commercial seakeeping software tool to address the complex problem of ship motions in waves. C12/M12 As a part of the group assessment, students must undertake experimental tests to the international standards to calculate the roll damping of a ship model and predict its seakeeping responses in waves. During these experiments, students will engage in practical tasks such as calibrating and ballasting the model. C16/M16 As part of the continuous assessment in this module, students must demonstrate effective teamwork and individual performance. They are expected to complete assigned tasks and evaluate both their own and their team's performance based on predetermined assessment criteria.
