Flap-type wave energy converters: From accelerated testing to fault detection

Faults in complex systems such as Wave Energy Converters (WECs) are inevitable. WECs are expected to work in harsh environments to produce more power which increases the possibility of major failures. Increasing the reliability of WECs calls for the development of early Fault Detection (FD) algorithms which needs understanding of the enormous...

Vibration-assisted installation and decommissioning of a slip-joint

The structural failure of grouted connections for offshore wind turbines focused the industrial attention towards different and innovative solutions to guarantee a safe connection between the monopile foundation and the turbine tower. An alternative option to the traditional grouted joint is a direct steel-to-steel connection, also called a...
