MAR8052 : Dynamics of Subsea Installations

Semesters
Semester 2 Credit Value: 10
ECTS Credits: 5.0

Aims

A1: To introduce and develop the design concepts for fixed and floating offshore oil and gas platforms, umbilicals and risers
A2: To provide the knowledge required to understand the factors influencing the dynamic behaviour of fixed and floating offshore platforms, umbilicals, risers and subsea pipelines
A3: To develop skills in order to predict the dynamic motion and structural response of fixed and floating offshore platforms, umbilicals, risers and subsea pipelines

Outline Of Syllabus

1. Metocean Issues: Introduction to wave theories and their influence on offshore operations including:
• wave, wind and current force predictions,
• sea states and regular and irregular wave analysis
2. Hydrodynamic Analysis: Study of the application of hydrodynamic principles to offshore and subsea structures including :
• the analysis of single and multi-degree of freedom systems;
• use of rigid-body equations of single and multi-body systems;
• the study of natural frequencies and vortex shedding and vortex induced vibration in pipelines and riser systems;
• the prediction of the dynamic motion and structural response of fixed and floating offshore structures;
• hydro-elastic response analysis;
• influence of floating installation motions on riser behaviour.
3. Orcaflex Software: Introduction to the use of the Orcaflex software to analysis problems in static and dynamic analysis of offshore and subsea systems.

Teaching Rationale And Relationship

Directed study and the formal lectures will provide an effective method for students to assimilate the knowledge content, define the scope of the syllabus topics and attain the required knowledge and skill outcomes (ISO1-4). The directed study allows students to work through material at their own pace allowing them to develop an in-depth understanding of the material (IKO1-4).

Assessment Methods

Assessment Rationale And Relationship

The exam tests acquisition of a clear general knowledge of the subject plus the ability to think and analyse a problem quickly, to select from and to apply both the general knowledge and detailed knowledge of aspects of the subject. The exam also assesses problem solving skills, the ability to work unaided and to communicate clearly and concisely in writing. The essay or post-school assignment provides students with the opportunity to demonstrate their numerical analysis and information literacy skills. The coursework also assesses written communication skills.
The Graduate Skills Framework entries indicated as 'A' are also assessed in these ways.
