The Double Slip Joint is being developed by KCI to replace grouted or bolted connections between the transition piece and monopile of wind turbine foundations. Together with partners Van Oord and SIF a joint project has been set up with support from TKI-Wind op Zee. A scale 1:5 prototype for an 8 MW offshore wind turbine is being tested in the laboratory of Knowledge Centre WMC.
The prototype diameter is 1.6 m. The longest component is about 15 m long (12 ton). The smaller main part is about 6 m long (5 ton). Test plans and test results will be reviewed by DNV-GL.
Two members from the WMC materials research team, Francisco Lahuerta and Iuri Rocha, took part on the IRPWind Mobility Programme, aimed at fostering collaboration between research organizations involved in the IRPWind project. Two research proposals were submitted to the programme and were both approved, resulting in two visits to the DTU Risø campus in Roskilde, in collaboration with Lars Pilgaard Mikkelsen from DTU Wind Energy.
The fifth edition of the International Conference on Computational Modeling of Fracture and Failure of Materials and Structures (CFRAC) took place from 14 to 16 June in Nantes, France. WMC researcher Iuri Rocha attended the conference with the work entitled "Multispatial/multitemporal homogenization analysis of hygrothermal fatigue in glass/epoxy composites", presenting a novel constitutive model for epoxy incorporating viscoelasticity, viscoplasticity, time homogenization and Model Order Reduction (MOR).
On March 9, 2017 the second expert meeting took place in the context of TKI Wind op Zee R&D project C-Tower. Engineers of offshore contractors, turbine developers and research institutes gave valuable feedback on the composite tower design. The development of a lightweight composite tower for the offshore wind industry aims to achieve cost savings through weight reductions and use of new materials. The 100-meter composite tower for a 10 MW wind turbine has a design life of at least 20 years under offshore conditions. The current design achieved a weight reduction of almost 40% relative to a conventional steel tower. The project aims to have 50% weight reduction, this will need further optimization. In spring of 2017 a 5-meter scale model will be produced and tested. The project is carried out by project partners WIND2020, Jules Dock Composites and Knowledge Centre WMC and will be completed in 2017.
