Course Overview

Offshore production of oil and gas requires transportation of the oil and gas from where it is produced to shipping vessels, storage tanks or refinery.  The transportation is done using pipelines which are installed on the seabed. This course examines the engineering and scientific concepts that underpin the selection of the material and size of such pipelines as well as safe installation and operation. The environmental impact and the role played by the seabed profile are also discussed. Contribution from industry-based practicing engineers is used to inform students of current practices and technologies in subsea pipelines.

Course Description

This course focuses on fundamental relationship between the stresses and deformation developed in subsea pipelines and the imposed installation, environmental and service loads.  Significant emphasis is placed on the design implications of the material deformation, geometric imperfection, and variability in the material properties. Methodologies for mitigating against pipeline failure, including seabed preparation and corrosion prevention are discussed.  Environmental impacts of pipeline installation and associated legislative framework are examined. Expertise in the use of pipeline design Standards (e.g. BS PD8010 and DNV-OS-F101) is developed throughout the course.    Students carry out a continuous assessment exercise to enhance their intellectual ability and transferable skills.  

The topics covered will include:

•        Overview of pipeline design, including commercial and environmental considerations, national and international design codes, and technological challenges.

•        Site investigation and pipeline routing, including soil classification, site survey and preparation, , HSE requirements, human and environmental factors.

•        Stress analysis based design.

•        Design against failure, including buckling and collapse.

•        Pipeline on-bottom stability, hydrodynamic loads on pipelines, pipeline-soil interaction response and modelling, pipeline seabed spanning response and evaluation.

•        External corrosion of pipelines and its prevention.

•        Pipeline ancillary equipment design including PLEMs, protection devices, etc.

Pipeline installation methods and installation analysis techniques.

Teaching Breakdown

More Information about Week Numbers

Details, including assessments, may be subject to change until 31 August 2023 for 1st half-session courses and 22 December 2023 for 2nd half-session courses.

Summative Assessments

Three-hour written examination paper (80%) and continuous assessment (20%).

The continuous assessment will be based on the report and presentation on a group design exercise.

The re-sit will comprise of re-doing the failed element/s (exam and/or coursework assessment/s) from the 1st attempt with a maximum CGS mark of D3. The marks for other elements (successfully passed) will be carried over. Resit mark of either RP or RF will be recorded.

Formative Assessment

There are no assessments for this course.


a)             Assessment grade and written feedback will be provided on group design report within three weeks of submitting the report.

b)             Students can obtain feedback on their understanding of key aspects of the course at the weekly tutorial/discussion sessions.

c)              The discussion board on myAberdeen will used to provide feedback and respond to student questions and comments.

Students requesting feedback on their exam performance should make an appointment with the course coordinator within two weeks of the publication of the exam results.
