EG55F2: PIPELINES AND SOIL MECHANICS (2014-2015)

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 group design 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 and commissioning.

For students studying for MSc Subsea Engineering, MEng in Mechanical Engineering with Subsea Technology (Studies), and MEng in Civil Engineering with Subsea Technology (Studies).
