About the position

We have a vacancy for a PhD position on Impact of submarine slides on anchorage systems.

Norwegian Public Roads Administration has since 2012 worked with development of the E39 Bjørnafjorden fjord-crossing project. Bjørnafjorden is approximately 550m deep with relatively steep slopes along the shores. The floating bridge is planned to be anchored with a mooring system to foundations or anchors at seabed. Two anchor groups are located near a slope where a recent Geohazards study show that there is a high probability that these anchors can be hit by a submarine slide. Acquiring deeper understanding of submarine landslides, its impact on the anchors and mitigation methods will be important for the E39 project. One of the most relevant mitigation measure is to design the anchors such that they can withstand major submarine landslides. This will require to reduce the uncertainties in the existing knowledge such as; the sediment thickness in the release areas, the flow (rheological) properties of the sliding materials, whether the slide/flowing materials will plough or not, landslide type, velocity and volume, disintegration process of landslide masses and probable scouring depth around anchors.

This PhD is jointly supported by E-39 project, Norwegian Public Roads Administration and the Department of Civil and Environmental Engineering at NTNU. The work will be performed in close cooperation with NTNU, E-39 project team at the Norwegian Public Roads Administration.

The position reports to Professor Steinar Nordal.

Main duties and responsibilities

Accordingly, a PhD study to contribute to the ongoing work by the E39 project group has been proposed. The study aim to fill the gap in the existing knowledge about how submarine slides may impact anchors on the seabed. The PhD study will look for solutions and explore possibilities to calculate impact forces more accurately and to propose viable solutions to alleviate impact of submarine slides on the anchors. Of particular interest is to improve the understanding of the impact forces from the sliding mass. An attempt shall be made to establish the representative rheology and the flow behavior of material to assign high degree of confidence to the input parameters for the numerical calculations. The disintegration rate of the slide material will be essential for landslide types, velocity, impact forces on anchors and the erosion. Through the study of submarine slide, a physical and numerical idealization will be created so that parameters important for the slide/flow can be estimated or measured. In the physical and numerical models, countermeasures will be studied with respect to forces, efficiency and functionality.

Qualification requirements

PhD candidate:

The PhD-position's main objective is to qualify for work in research positions. The qualification requirement is completion of a master's degree or second degree (equivalent to 120 credits) with a strong academic background in Geotechnical Engineering or equivalent education with a grade of B or better in terms of NTNU's grading scale. Applicants with no letter grades from previous studies must have an equally good academic foundation. Applicants who are unable to meet these criteria may be considered only if they can document that they are particularly suitable candidates for education leading to a PhD degree.

In the application the candidate is encouraged to present his or hers motivation for this particular PhD study and briefly sketch how he or she expect to the aims of the project.

The appointment is to be made in accordance with the regulations in force concerning State Employees and Civil Servants and national guidelines for appointment as PhD, postdoctor and research assistant

NTNU is committed to following evaluation criteria for research quality according to The San Francisco Declaration on Research Assessment - DORA.
