Potential output of the project:

An important issue to be considered in the structural integrity of offshore wind turbines is the design and life assessment of the connection between the monopile foundation and the transition piece (MP-TP connections). These connections are subject to variable loads and stresses imposed by the forces and moments generated by the effects of winds, waves and currents. Therefore, careful considerations must be made to design these connections against fatigue cracking and failure. Flanged bolted connections are widely used in the currently deployed offshore wind turbines. However, the suitability of these connections for future generation of offshore wind turbines, which will be much larger in size and capacity, needs to be evaluated and compared with alternative solutions do not involve bolts such as wedge connections. The objective of this research is to investigate the fatigue performance of the current and future MP-TP connection types by accounting for different factors that affect fatigue performance such as marine environment, welding and variable amplitude loading. Through theoretical, numerical and experimental study will be analysed the effect of the different factors on fatigue life of both bolted and non-bolted MP-TP connections. In particular, the research will aim to verify the design on non-bolted connections and determine any threats to structural integrity and limitations on safe working life.
