ENERGY GEOTECHNICS - 2019/0

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.

Assessment pattern

Alternative Assessment

None

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.

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 investigation 
• to provide a broader understanding on the geotechnical design aspects of the geothermal energy pile
• to understand design challenges involved in deep geological storage facilities related to nuclear waste disposal, carbon geosequestartion, compressed air energy storage

Learning outcomes

Methods of Teaching / Learning

The learning and teaching strategy is designed to:

• provide a specialist knowledge of foundation design and deep geological storage facilities 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)

 

 

Indicated Lecture Hours (which may also include seminars, tutorials, workshops and other contact time) are approximate and may include in-class tests where one or more of these are an assessment on the module. In-class tests are scheduled/organised separately to taught content and will be published on to student personal timetables, where they apply to taken modules, as soon as they are finalised by central administration. This will usually be after the initial publication of the teaching timetable for the relevant semester.
