Dr Peter Greave is ORE Catapult’s Senior Research Structural Engineer who responsible for projects involving structural design and testing of wind turbine blades. Since completing his doctoral studies on bi-axial fatigue testing of blades, Peter has continued to be heavily involved in the development of the technology (which aims to perform a faster and more realistic fatigue test on blades by accounting for the fact that in real life blades are continually bent about two axes at once) with tests on a 40m, 62m, 88m blade (the largest in the world at the time) and is now once more involved in testing the longest blade in the world – the 107m blade manufactured by LM Wind Power for the GE Haliade-X.

Peter is also an experienced structural analyst – a recent example of this is the Leading Edge for Turbines (LEFT) project aimed at a technology transfer between the helicopter industry and wind turbines of a nickel-cobalt erosion protection shield with extremely good erosion performance. Peter’s work was focused on validating the adhesive joint using a sub-modelling approach and cohesive zone elements. Fracture mechanics testing was also performed to validate the joint.

His most recent work is the Joule Challenge, which was a BEIS funded project to investigate upscaling of floating wind turbines to 20MW. Peter was involved in optimisation studies on the floater and tower using an in-house code, and was also responsible for the loads calculations. He has an MEng in Mechanical and Design Engineering from Newcastle University, and MSc in Renewable Energy (also from Newcastle University) and a PhD from Durham University. He is also a chartered engineer (CEng).
