Partial CEng Programme Level Learning Outcomes

Having successfully completed this module you will be able to:

• Hydrostatic and stability calculations use a basic understanding of mathematics and physics and are a vital aspect of Maritime Engineering and assessed through the examination. Links between the calculations and various regulations are explored.
• Students conduct hydrostatic calculations through programming and must select and use appropriate numerical methods for interpolation and integration.
