PhD Candidate in floating structures for the next generation of ocean industries

For a position as a PhD Candidate, the goal is a completed doctoral education up to an obtained doctoral degree.

The Department of Marine Technology, NTNU has a vacancy for a PhD candidate focusing on floating structures for the next generation of ocean industries. This PhD project is part of the Centre for Research based Innovation SFI BLUES. The centre aims to develop new knowledge and technology that will contribute to solving the industrial and societal challenges the world is facing. The ambition is to enable Norwegian industry to create new types of floating stationary structures, which will satisfy the needs and requirements from renewable energy, aquaculture, and coastal infrastructure. The Centre is led by SINTEF Ocean, with research partners NTNU (Norwegian University of Science and Technology), the Norwegian Geotechnical Institute (NGI) the Norwegian Meteorological Institute (MET) and SINTEF Industry. The Centre involves more than 10 national and international industrial partners.

The focus of the PhD project is on the design and dynamic analysis of multi-modular floating structures. Floating structures composed of interconnected modules are proposed as economical solutions for floating solar power plants, floating islands, floating hubs, and other applications. Experience with such structures is limited, however, and there are limited design guidelines and simplified tools for early design. For design optimization, rapid screening of concepts is desirable, but the screening needs to capture trends in important performance criteria with an acceptable level of accuracy. ​Dominant physical effects must be included in the analysis. This includes possibly nonlinear structural responses in connections and nonlinear wave and current loads.

The performance criteria for different types of multi-modular structures are not very well defined at present. In any application, one may expect that the dynamic loads in the connections between floaters will be an important constraint. Required sizing and acceptable motions and accelerations for floating solar will differ significantly from those for i.e. a floating living space. ​

The objective of the PhD project is to develop efficient simulation approaches which capture the most critical dynamic responses of generic multi-modular floating structures in wind and waves, and to use these approaches to better understand the dynamic responses and design trends for novel multi-modular floating structures.

Your will report to Supervising Professor Erin achynski-Polić.
