Stillingsbeskrivelse:

NTNU - knowledge for a better world

The Norwegian University of Science and Technology (NTNU) creates knowledge for a better world and solutions that can change everyday life.

Jobbnorge ID: 122744

A PhD position is available at the Department of Marine Technology, NTNU, with affiliation to the Centre of excellence AMOS. The research will be carried out at the Marine Technology Centre in cooperation with other researchers at NTNU and MARINTEK.

 

The wind industry has developed very fast in recent years, moving from onshore to offshore in shallow water and then in deep water, while turbine size also continues to increase. Many floating wind turbine concepts have been proposed for water depths larger than 100-200 m; with increasing turbine size. Global dynamic analysis of floating offshore wind turbines has typically focused on the dynamic loads in the mooring system, tower, and blades, while structural design of the hull has been based on hydrostatic and hydrodynamic loads in the frequency domain, while wind loads have been considered in a simplified manner. Both load effects for ultimate and fatigue design are of interest. The dynamic loads in the hull due to coupled wind-wave action are of interest in the structural design. For some platforms and turbines, the flexibility in the tower and hull may also be important for the global behaviour - considering interaction with the rotor.

 

Hydrodynamic loads for large-volume structures depend strongly on frequency, and novel methods are needed to simultaneously and efficiently account for structural flexibility and distributed hydrodynamic loading in coupled global analysis. With the inclusion of the correct hydrodynamic loads in the global modelling, it becomes possible to optimize the structural design of the hull in order to further reduce costs of offshore wind turbines, currently the major challenge for the wind energy industry.

 

Time domain analyses prevail for design analyses today. Their efficiency needs to be improved. Moreover, further development of frequency domain methods for the global analysis of both stochastic wave and wind loads are needed.

 

Qualifications 

Applicants must have an MSc (or equivalent) degree in marine technology, ocean engineering, mechanical engineering, or wind engineering, especially within disciplines such as structural dynamics, hydro- and aero-dynamics, preferably with some experience regarding automatic control and wind turbine technology. Research or engineering experience on marine operations or in offshore wind industry is considered an advantage.

 

Excellent English skills, spoken and written, are required. Applicants from non-English-speaking countries outside Europe must document English skills by an approved test. Approved tests are TOEFL, IELTS, Cambridge Certificate in Advanced English (CAE) or Cambridge Certificate of Proficiency in English (CPE).
