DNV GL has announced three Joint Industry Projects (JIPs) which are aimed at developing recommended practices for the global wind industry to further develop industrial accepted design practices and methods, lower risks and reduce costs.
The three JIP’s are:
- Coupled dynamic analysis of floating wind turbines; the aim of this JIP is to gain a deeper understanding of the coupled dynamic analysis of floating wind turbines and develop recommendations to effectively guide designers and engineers. The project is scheduled to start in the second half of 2015, with final review and publication of recommended practices in the first half of 2017. A total of 8-12 participating companies are anticipated.
- Validation of turbulence models; The aim of this JIP is to gain a deeper understanding of which turbulence methods should be used under which circumstances. Specific recommendations shall be published to guide the industry through the load validation and site assessment process, which relies on accurate turbulence models. The project is scheduled to start in the second half of 2015, with final review and publication of recommended practices in the first quarter of 2017. A total of 15-20 participating companies are anticipated.
- Integrated approach to design, installation and maintenance of heavy duty bolted joints; The aim of this JIP is to enable wind turbine designers to further optimize the structural bolted joints and thus the dimensions and weights of the joined parts, while lowering the risk of damage in the field. It will also enable wind farm operators to reduce costs related to inspection, corrosion protection and retightening of bolted joints which make up a major part of the operating expenses, especially offshore. The project is scheduled to start in autumn 2015 and is planned to run until the end of 2016. A total of 6-10 participating companies are anticipated.
