OLE-CHRISTIAN EKEBERG

• JUNE 3RD

Studies of ice ridge shape and geometry from upward looking sonar data

Ekeberg is currently Senior Engineer in DNV GL and works with challenges related to Arctic oil

and gas exploration. He is currently the project manager of the RigSpray project working with the

development of knowledge, models and a tool to estimate marine icing loads required for design.

Main supervisor:

Knut V. Høyland, SAMCoT WP3 Leader and Professor at the Department of Civil

and Transport Engineering.

TORODD NORD

• NOVEMBER 20TH

Force and state estimation on bottom-founded structures prone to ice-induced vibrations

During his postdoc, Nord is working with the estimation of ice forces and responses of structures

that suffer from dynamic ice actions. Currently enrolled in different courses at the Department

of Cybernetics, Nord aims to acquire further knowledge on estimation methods. And in doing so,

assess their applicability on estimation problems related to dynamic ice-structure interactions.

EMILIE GUEGAN

• DECEMBER 10TH

Erosion of Permafrost Affected Coasts: Rates, Mechanisms and Modelling

Guegan’s postdoc builds on the research she did for her PhD, where she will continue her studies of

frozen soils and erodibility, as well as build a computer model that allows her to combine what she

has learned about cliff stability and erosion with information on wave action. Guegan also plans to

continue and extend the scope of her fieldwork to include jet erosion tests, which she believes very

applicable for Arctic coasts.

Main supervisor:

Professor Steinar Nordal at the Department of Civil and Transport Engineering.

ANDREI TSARAU

• DECEMBER 15TH

Numerical Modelling of the Hydrodynamic Effects of Marine Operations in Broken Ice

Andrei Tsarau plans to do experimental and numerical work linked to research subjects such as

waves in ice and wave/ice actions on structures. In the light of the observed climate change in the

Arctic, there is a need for in-depth research in the field of wave/ice interaction. This research will

focus on marginal ice zones (MIZ), transitional areas between the open ocean and the pack ice

cover. Here ice actions contribute to the formation of ice floes as ocean waves penetrate into the ice

field. Hence an important research both for winter navigation as well as for offshore structures.

Main supervisor:

Sveinung Løset SAMCoT WP4 Leader and Professor at the Department of Civil

and Transport Engineering

QIN ZHANG

• DECEMBER 17TH

Image Processing for Ice Parameter Identification in Ice Management

In addition to her work as PhD candidate, Zhang collaborated in the OATRC15 research cruise.

During this field activity, a helicopter was used to capture ice conditions in the marginal ice zone

(MIZ). Zhang developed the algorithms that facilitated the online imaging processing.
