First-full scale Wrapped Composite Joint sees light of day

Tree Composites produced the first full-scale Tree Composites Joint (TC-joint) within the WrapNode-I project, which is supported by the Netherlands Enterprise Agency (RVO) and TKI Wind op Zee. With a height of 2.6 meters and a length of 10 meters, and a total weight of around 6 tons, it is the largest joint that Tree Composites has produced so far.

Big joints require big testing machines, and therefore the full-scale joint will be tested next month in CRONOS at OCAS, Belgium. The test aims at performance validation of the full-scale wrapped composite joint under cyclic loading. The joint dimensions and testing loads are based on a jacket design with wrapped composite joints that was performed in the Wrap Node-I project. Next to the cyclic load test also, two full-scale wrapped composite joints will be tested in static loading, and we will witness its performance together with our partners AOC, BUEFA, Enersea, GROW, HSM Offshore Energy, Salzgitter, Shell, Siemens Gamesa, Smulders, TU Delft and Vattenfall. We are proud that we produced the TC-joint at full-scale, which marks a major milestone for the
commercial roll-out of TC-joints in next-generation offshore wind support structures.
