# Marine Engineering Modules

Year 1

### Materials in the Marine Environment

MNO1101

This module teaches students to consider the role of materials in the marine and offshore environment and the particular challenges that this environment poses to the selection of materials.

The syllabus is designed to develop a knowledge of the structure of materials, showing how the microstructure and manufacturing route can influence the properties of the material.

It also considers material failure, typical mechanisms of failure and how failure can be prevented. The course will include case studies and examples of the marine and offshore industry.
