Systems Design and Computing for Ships

Learning Outcomes

Partial CEng Programme Level Learning Outcomes

Having successfully completed this module you will be able to:

• As part of a rudder design assignment, students will select appropriate materials for use in analytical models and incorporate suitable practical limitations on the fabrication of the rudder.
• Use engineering principles to analyse experimental rudder data from wind tunnel tests, to determine the forces acting on a new rudder design.
• As part of a small group systems engineering assignment, students will identify environmental and societal stakeholders of a maritime system and use systems thinking to determine their requirements and methods of verification and validation of these requirements.
• This is assessed through a group assignment which presents the results of systems engineering review utlizing diagrams to illustrate the students' system thinking. In a second group assignment, the students need to present their technical design for a Ship's rudder including suitable tables, figures and discussion of results.
• As part of a small group design assignment, students will use mutliple techniques (experimental analysis, rules based calculations, FEA and CFD) to design a ship's rudder.
• In small groups, design a ship's rudder which meets class society rules.
• Work on assignments both in a group and individually. When working in a group highlight contribution to the work made by each member of the team.
• Write python programs to model and solve the motion of simple dynamic systems.
• In small groups, use a systems approach to find the solution of a maritime system such as a small work boat or the sub-system of a larger maritime system such as the manoeuvring sub-system of a cruiseship. The assignment involves using system thinking to identify stakeholders, requirements, functions, before generating and evaluating potential solutions.
