This biannual course is taught on years 2015-2016, 2017-2018, ....
iCampus : LAUCE2167
Basic concepts of soil classification, effective stress, compressibility, shear strength, laboratory and site investigation, design of shallow and deep foundations.
The objective of the course is to provide an introduction to current geotechnical engineering practice in offshore conditions. Over the last decades, offshore geotechnical engineering has grown up as an independent branch of geotechnical engineering due to significant differences in the scale of foundation elements dealt with but also due to the challenging soil behaviour characterization.

Specific learning outcomes of the course
At the end of the course, the student will be able to:
' Describe the current techniques of offshore site investigation and their fields of application.
' Describe behaviour issues of offshore soils and identify potential issues.
' Identify the most significant parameters that affect the performance of offshore foundation elements
' Determine the capacity of foundation elements and anchors.
The contribution of this Teaching Unit to the development and command of the skills and learning outcomes of the programme(s) can be accessed at the end of this sheet, in the section entitled “Programmes/courses offering this Teaching Unit”.
Oral exam with written preparation.
Lectures will be given by means of slides in classroom. Teaching material to support the learning process will be electronically available.
The topics covered in the lecture sessions include:
- Offshore site investigation: geophysical and geotechnical methods and their interpretation.
- Behaviour of calcareous sands, cemented soils, impact of cyclic loading.
- Installation of suction caissons, and evaluations of their capacity.
- Installation and capacity of anchors (suction anchors, VLA).
- Capacity of shallow foundation, spudcans.
- Installation of pipelines and pipeline protection.
Slides, lecture notes and supplementary documentation (available online).
