Aims

The marine structures module aims to explain the fundamental naval architecture concepts for the global and local structural response of a ship in ocean waves.

Outline Of Syllabus

The module provides an awareness of structural principles and their application to marine related problems. The syllabus is in three parts:
Global Strength: Learn how a large ship balances in the water and how the weight and buoyancy forces create global bending moment on the hull structure. Link the behaviour of a ship to that of a simple beam. Develop analysis approaches to determine the wave loading and strength of the metallic ship structure.
Local Strength: Learn how to represent the stiffened plates typically found in a steel ship for the purposes of structural analysis and design. Link this to concepts of beam theory, column buckling and truss structures. Develop analysis skills in beam and buckling strength prediction.
Strength of Advanced Materials: Learn about the types of advanced polymer composite materials that can be used in specialist marine craft. Compare and contrast the differences between steel and other materials applied in a marine environment. Develop approaches to select different materials for specific applications. Determine the stiffness and strength of a composite part.

Intended Knowledge Outcomes

IKO1 Recognise and apply key naval architecture concepts of weight, buoyancy and equilibrium (C1)
IKO2 Calculate load, shear force and bending moment for a ship in still water and poised on a wave (C1)
IKO3 Link bending calculations to hull deflection, shear stress and bending stress and describe the influence of shear deflection and stress on bending (C1, C2)
IKO3 Select and design the scantlings for a ship midship section (C5)
IKO4 Apply fundamental column buckling methods to ship-type applications. (C1)
IKO5 Analyse the forces and displacements in a truss structure. (C1)
IKO6 Discuss the requirements and methods of solving indeterminate structural problems (C6)
IKO7 Explain elastic beam theory; the limitations of moment-area methods and degrees of fixity in end constraints. (C17)
IKO7 Describe the properties of 2D stresses and strains and criteria for failure (C1)
IKO8 List the key stages in manufacture of any composite component and describe anufacture processes from composite materials (C1)
IKO9. Compare the properties of composite materials and their relative advantages (C2)
IKO10 Design a composite sandwich including contributions from the skin and core (C2)

Intended Skill Outcomes

ISO1 Apply longitudinal strength calculations to a ship (C3)
ISO2 Design a basic midship section with adequate strength (C5, C6)
ISO3 Analyse a simple truss structure and also consider elastic buckling (C2)
ISO4 Evaluate the minimum section modulus of a stiffened panel. (C3)
ISO6. Calculate deflections, slopes, shear forces and bending moments on indeterminate beams (C2)
ISO7. Determine critical stresses in stiffened panels under lateral loads (C2)
ISO8. Utilise strain gauge results to determine principle strains and stresses (C2)
ISO9 Calculate the Young’s moduli and strength of a composite materials (C2, C5)
ISO10 Apply design skills to configure a complex composite part (C5)

Teaching Rationale And Relationship

The use of lectures as the principle teaching method is an effective means to provide students with the acquisition of the knowledge and skills within this module

Practical sessions provide the forum for the knowledge and understanding developed through formal lectures to be integrated into a coursework exercise to load an idealised ship with a specified amount of cargo, evaluate the resulting loads, forces and moments. Suggest midship section scantlings and complete local structural analysis

Assessment Rationale And Relationship

The written examination will assess the breadth of knowledge, understanding and ability to perform related ship strength calculations. This medium also allows students to demonstrate intended learning outcomes across a wide range of topics from the syllabus (IKO5-IKO10, ISO5-ISO9).

The coursework assesses ability to analyse the global strength of a ship, and provides students with the opportunity to demonstrate written communication, teamwork, planning, organisation, initiative, problem solving and acquisition of learned skills (IKO2-IKO4, ISO2-ISO4)
The formative assessment enables learning and feedback relating to the fundamental equilibrium of a ship that underpins the entire course (IKO1, ISO1)
