Description
The primary cause of structural failure in a jacket-type offshore wind turbine is attributed to the fatigue deterioration of a local joint. In the context of wind and wave random loading, the structure undergoes a complicated multiaxial stress condition. The objective of this training is to establish a multi-scale modeling approach for a jacket-type offshore wind turbine. In this approach, the local joints of the jacket structure will be represented in a highly detailed manner using solid elements, while the other components will be modeled using the conventional beam element technique.
This study delves into the examination of codes and standards used in the design of maritime structures, with particular emphasis on the Limit State Design methodology. This technique takes into account probable failure scenarios, including Ultimate Limit States (ULS) and Serviceability Limit States (SLS), to guarantee the safety and dependability of the structures.
During the course, the following topics will be covered.
- In-service: In place, Reserve strength
/push-over, ship impact, seismic, fatigue
- Pre-service: Lift, load-out, transportation, buckling.
- Offshore structures' SCF calculations.
- Analysis of the fatigue limit state (FLS), ultimate limit state (ULS), and serviceability limit state (SLS) of wind turbine foundation structures
In conjunction with the acquisition of FEA training, it is important to possess a comprehensive comprehension of the many regulations and standards that pertain to offshore wind turbine constructions. DNV GL is a prominent certifying group that has formulated many standards for these structures.
The course also goes into nonlinear concrete simulations, which are critical in precisely forecasting the behavior of concrete buildings. Stress-strain diagrams, contact nonlinearity, and buckling analysis will be covered.
Participants will have developed a thorough grasp of structural design using FEA, including the use of advanced nonlinear simulations, by the conclusion of this course. They will be prepared to confidently design and assess wind structures, guaranteeing their safety and optimum performance.
