Perforation of Monopiles to Reduce Hydrodynamic Loads and Enable use in Deep Waters

The offshore wind industry in Europe has experienced significant growth in the past decade, with wind farm development mostly focusing on the shallow area's in the North Sea. Naturally, the market is driven to reduce the Levelised Cost of Electricity (LCoE) to become more competitive with fossil fuels and less dependent on government subsidies....

A heat-transfer based method for slip-joint contact area measurement

Delft Offshore Turbine (DOT) is developing a new offshore wind turbine, including, amongst other innovations, a slip-joint that connects the turbine tower and monopile foundation. The slip-joint is a mechanical, friction-based connection that provides many advantages over a bolted or grouted connection, such as the ability to support high loads,...
