Graduation assignment - Pile Driveability
The Swiss-based Allseas Group, founded in 1985 and headed by Edward Heerema, is a global leader in offshore pipeline installation and subsea construction. Allseas Engineering, located in Delft, provides project management and engineering services to other subsidiaries of the Allseas Group.
Assignment: Pile driveability assessment for hard clays and very dense sands
Allseas often uses piles as a start-up method for pipelaying projects. Pile driveability refers to the ability of a pile to be safely and economically driven into the seabed to support the required bearing capacity and possibly to a minimum required penetration depth. Factors that affect pile driveability include the hammer driving system characteristics, pile type/size/length, and soil resistance behavior. Pile design is a multidisciplinary process involving structural, geotechnical and constructability considerations.
The objective of this assignment is to understand and analyse soil behaviour during pile driving in hard soils. The challenge will involve a literature research, identifying the different mechanisms and developing a model to determine pile driveability in hard soils.
We are looking for a student with an affinity for the correlation between theoretical models and real-world applications. During this project you will develop both your engineering and your scientific skillset.
The assignment requires a solid understanding of soil mechanics and foundation design issues; experience with FEM software package is preferable. You will be expected to work independently, although multi-disciplinary support will be provided.
This graduation assignment is available for a period of 9-12 months.
