1. Early Gear Failure Detection in Fatigue Testing of Driveline Components
University essay from KTH/Maskinkonstruktion (Inst.)Abstract : Early failure detection has been an integral part of condition monitoring of critical systems, such as wind turbines and helicopter rotor drivetrains. An unexplored application of early failure detection is fatigue testing of driveline components. READ MORE

2. Self-levelling Platform Concept for a Winch-based, Single Point Absorbing, Wave Energy Converter
University essay from KTH/Maskinkonstruktion (Avd.)Abstract : This report covers a bachelor thesis project to design a concept for a levelling system to a point absorbing wave energy converter that uses a winch with a chain, which has restricted capabilities to bending and thus requires a system which compensates for this. First of all, a literature study was made to see if there were any technologies that could be used, and also a wide search for information about the wave conditions in the Baltic sea were performed to find what requirements would be necessary for the concept to be able to withstand the conditions faced there.

3. A durable mooring system for a winch-based wave energy converter
University essay from KTH/Maskinkonstruktion (Inst.)Abstract : This project has dealt with the developing a new technology for a renewable energy source, the wave energy, which is considered as one of the renewable resources with a potential to contribute to an energy production corresponding to about 10% of the world’s energy consumption nowadays. A point absorber concept that is using a Power Take-off (PTO) unit converts the sea surface wave motion into electricity thanks to a buoy at the sea surface which is moved by the waves. READ MORE

4. A fatigue investigation in a Kaplan hydropower station operated in frequency regulating mode
University essay from KTH/EnergiteknikAbstract : Due to the increase of intermittent power in the Nordic grid the need for frequency regulation increases. Hydropower has the ability to respond fast to frequency changes in the grid and is the power source mainly used to regulate the frequency in the Nordic grid. READ MORE
