  • Offered for Year: 2022/23
  • Module Leader(s): Dr David Trodden
  • Owning School: Engineering
  • Teaching Location: Off Campus
Semester 1 Credit Value: 10
ECTS Credits: 5.0


To introduce students to the behaviour of material and structural response to the marine environment.

Outline Of Syllabus

The module will be divided broadly into the following themes:
Fatigue and fracture mechanics
Fatigue assessment: S-N curve, Miner's rule, Deterministic fatigue analysis, Spectral fatigue analysis, Narrow and broad band, Non-linearities affecting spectral and fatigue analysis.
Fracture assessment; Brittle fracture, Application of fracture mechanics to fast fracture, Crack propagation.
Marine corrosion: Nature and diagnosis of marine corrosion problems, nature of corrosion, Marine corrosion testing, Environmental factors in corrosion of metals in seawater and sea air, Crevice corrosion, Galvanic corrosion, Cathodic protection, Effects of stress, Application to hull structures.
Materials and NDT (non-destructive testing): Types of non-destructive tests, Methods of examination for defects, Radiographic examinations, Methods of magnetic analysis, Magnetic and particle method, Methods of electrical analysis.

This modules will include preschool reading, examples, an intensive school (five days), an examination, and a post school assignment.

Teaching Rationale And Relationship

Students are encouraged to develop their knowledge and understanding of the subject by independent reading for which they are given guidance in the distance learning material (IKO1-2). The preschool study is reinforced via lectures during the intensive school itself. The use of design during the intensive school and work-based assessments and application after the intensive school also enable the students to learn. Subject specific skills (e.g. IT and project planning) are developed via the distance learning material, which is delivered by a web-based system (Canvas). Cognitive skills (problem solving/ decision making) are taught primarily through case studies and design classes, and developed through work based assignments. Key transferable skills (communication, time management, ability to work alone etc) are developed through the work based post school assignment and via completion of the module itself, including the distance learning material (ISO1-12).

Should the public health situation require it, the present-in-person teaching activities will be replaced by a mix of synchronous and asynchronous online sessions.

Assessment Rationale And Relationship

Knowledge and understanding (IKO1-2) are assessed via the unseen written examination and the written assignment. Subject-specific and cognitive skills (ISO1-12) are assed via design exercises and the module assignments, as are communication skills (ISO10). The Graduate Skills Framework Skills indicated as 'A' are also assessed in this way.

The Zero Weighted Pass/fail Assessment is a formative assessment, but is compulsory to complete the module as forgoing it could hinder the student’s ability to perform during the post-school assignment.

Should the public health situation require it, the planned examination scheduled to be completed present-in-person
