Job title PhD in Marine Technology – Response Estimation and Wave Prediction for Offshore Wind Farm Installation and Operations. Company Department of Marine Technology, Norwegian University of Science and Technology (NTNU). Description of the job The Department of Marine Technology at NTNU offers a 3-year PhD position focused on response estimation based on remote distributed sensing of the wave field in an offshore wind park, in combination with metocean forecasting data. Cost- and risk-optimal installation and operation of offshore wind farms depend on accurate forecasts and predictions of environmental conditions and response of vessel and auxiliary systems. Improved sea-state and wave prediction can lead to real-time solutions for prediction of motion responses and wave loads during installation tasks such as turbine/blade installation as well as mooring and cable installation. The research task will further investigate exploitation of such methods for...

Job title PhD in Integrated Wind Turbine Modelling Tools for Drivetrain Health Monitoring. Company Department of Marine Technology, Norwegian University of Science and Technology (NTNU). Description of the job The Department of Marine Technology at NTNU offers a 3-year PhD position focused on developing near real-time hybrid, data-driven models considering the whole offshore wind turbine system and environmental loading for early fault detection in drivetrains. An offshore wind turbine installation is the result of a two-stage design process. As turbines get larger, the interaction between machinery and structure becomes more important. It is common practice to use a very simplified model of drivetrain in global analysis tools and ignore the coupling effects, often due to model complexity. This project is based on earlier experience in drivetrain and global models, aiming to build near real-time hybrid, data-driven models considering the whole system and...

Job title PhD Candidate in Seaweed Hydrodynamics. Company Department of Marine Technology, Norwegian University of Science and Technology (NTNU). Description of the job The Department of Marine Technology at NTNU offers a fully funded PhD position in the field of hydrodynamic loads on seaweed and macro algae. The application of the research is towards industrialization of seaweed production in general, and design of floating seaweed production facilities in particular. The main cost of a seaweed farm is the longlines, which there may be hundreds of kilometers of. The seaweed grows on the longlines and is exposed to waves and current at various stages of growth. The hydroelastic behaviour of the seaweed is not sufficiently well understood, and hence there are no good hydrodynamic load models. The purpose of this work is to increase the understanding of longlines with seaweed under sea loads and develop accountable hydrodynamic load models. The position is part...
