This module aims to:
-       Demonstrate the types and functions subsea structural systems focused on foundations, connection systems
and inspection vehicles.
-       Select and apply design and analysis procedures to subsea structural systems.
-       Provide knowledge and understanding of mooring systems and the analysis applied to different
configurations, components and equipment.
-       Introduce and develop the concepts of risk and reliability and demonstrate how these concepts relate to
integrity management decisions
-       Demonstrate how hazards are assessed and quantified using industry recognised techniques of FMECA and

Outline Of Syllabus

Subsea structural systems are playing a crucial role in supporting offshore infrastructure to meet global energy demands. Subsea configurations must operate in deeper and harsher environments and are increasing in complexity as energy systems move to renewable resources which are often highly distributed across larger areas of the ocean. This module introduces and develops the understanding of fundamental concepts and performance analysis of subsea structural systems and the supporting remote inspection vehicles that are crucial for installation, inspection and maintenance. This also includes knowledge of mooring systems design and analysis methods for offshore floating structures, and the module examines several crucial aspects of these systems.

This module also gives a thorough understanding of the risk management of these assets and analysis methods used in design and operation.

The syllabus comprises:
-       Subsea structural system concepts
-       Integrated analysis of subsea systems and remotely operated vehicles
-       Static and dynamic analysis methods for mooring and riser systems
-       Risk assessment concepts
-       Hazards and failure modes in offshore systems

Learning will be formatively assessed throughout the module through exercises and tutorials. The module will be summatively assessed through both a project-based exercise and written examination. The project based exercise will culminate in a technical report and demonstrate how the taught theory can be used practically to model and analyse a subsea structural system

Teaching Rationale And Relationship

The module will consist of lectures, tutorials and online resources which provide students with a structured format to assimilate the knowledge content and define the scope of each of the syllabus topics (IKO1-5)
Exercise and tutorial sessions provide students with the opportunity to gain feedback which enhances their learning which can be further applied in their summative assessment. (ISO1-5)

The independent study time is essential for students to work through the lecture material, in their own time and at their own pace
Time is allocated for students to both research and complete the coursework activity.

Assessment Methods

The format of resits will be determined by the Board of Examiners

Formative Assessments

Formative Assessment is an assessment which develops your skills in being assessed, allows for you to receive feedback, and prepares you for being assessed. However, it does not count to your final mark.

Assessment Rationale And Relationship

The Written Examination allows the students to demonstrate their basic knowledge and understanding of the subject as well as to demonstrate their problem-solving skills through short subject specific problems, under time constraints. This is similar to time constrained problems found in an industry setting. (IKO1-5)

The Problem-Solving Exercise allows students to demonstrate their knowledge and practical application of assessing the performance of a subsea system. This is a substantial element and requires numerical problem-solving techniques using a personal computer. (ISO1-5)
