Module overview

This module is designed to provide necessary geotechnical design concepts of deep foundation and deep geological storage facilities related to some of the current and emerging energy projects. They include renewable energy systems (offshore and onshore wind turbine generator foundations), foundations for offshore oil and gas installations, geothermal energy pile foundation and nuclear power plant foundations There will also be specialised lectures on high level nuclear waste disposal and carbon geo-sequestration, methane hydrates and compressed air energy storage.

Module aims

to discuss the energy challenge and introduce a new emerging discipline

to provide an appreciation of the complexity of foundation design in offshore and the technolgical challenges in deep water hydrocarbon exploration

to introduce the different types of foundations for energy projects and the guiding design principles

to provide ability to carry out analysis and design of foundations for offshore wind turbine, oil and gas installations, nuclear power station

to provide the ability to recognise the uncertainties in foundation design and need for site investigationĀ 

to provide a broader understanding on the geotechnical design aspects of the geothermal energy pile

Methods of Teaching / Learning

The learning and teaching strategy is designed to:


provide a specialist knowledge of foundation design related to energy sector, and will be delivered principally by lectures but also learning by analysing field data and through a course work.


The module is delivered principally by lectures with tutorial/question classes.

The learning and teaching methods include:


Geothermal energy pile foundation lectures/tutorials (6 hours)
Wind and marine foundations lectures/tutorials (3 hours)
Foundations for offshore oil and gas installation lectures/tutorials (3 hours)
Nuclear power plant foundations lectures/tutorials (3 hours)
Nuclear waste disposal lectures/tutorials (6 hours)
Carbon geo-sequestration lectures/tutorials (6 hours)
Methane hydrate and compressed air energy storage lectures (3 hours)
Directed and guided reading (78 hours)
Coursework (40 hours)


 

 

Assessment Strategy

The assessment strategy is designed to provide students with the opportunity to demonstrate


Knowledge and understanding of principles of specialist foundation design (LO’s 1-5) through a 2 hour unseen examination.
Solving open ended problems such as a foundation design using real data, ability to interpret soil test data to obtain the design parameters (LO 5) is assessed through coursework.


Thus, the summative assessment for this module consists of:

·         Examination [Learning outcomes assessed 1, 2, 3, 4, 5] (2 hours) {60%}

·         Coursework [Learning outcomes assessed 5] (40 hours) {40%}

Formative assessment and feedback

Formative Feedback will be through a range of self assessment exercises and quizzes held in the class.

Students will receive written feedback on their coursework.
