REGISTRATION:

The registration for the course must be done through AAU PHD Moodle, on a "first come, first served" basis.

The maximum number of participants is set to 24. The registration deadline is 15 November 2019.

Please note:

Important information concerning PhD courses:

We have over some time experienced problems with no-show for both project and general courses. It has now reached a point where we are forced to take action.

Therefore, the Doctoral School has decided to introduce a no-show fee of DKK 5,000 for each course where the student does not show up. Cancellations are accepted no later than 2 weeks before start of the course. Registered illness is of course an acceptable reason for not showing up on those days.

Furthermore, all courses open for registration approximately three months before start. This can hopefully also provide new students a chance to register for courses during the year. We look forward to your registrations.

    Reliability and Risk Analysis of Wind Turbines and Wave Energy Devices

    3-5 DECEMBER

    Reliability is a very important issue for both wind turbines and wind energy devices. Reliability is important both for estimating failure rates and probabilities for different components and members in structures, and for planning optimal operation and maintenance.

    In traditional deterministic code-based design the structural costs are influenced by the value of the safety factors. These reflect the uncertainty related to the design parameters. Improved design with a consistent reliability level for all components can be obtained by use of probabilistic reliability-based design methods, where explicit account of uncertainties related to loads, material
    strength, and calculation methods is made.

    The course will include the following topics:

    • Introduction to risk and reliability analysis
    • Stochastic modelling of uncertainties and failure rates, incl. Bayesian techniques
    • Reliability analysis of electrical and mechanical components
    • Reliability analysis of structural members by FORM/SORM and simulation methods
    • Reliability assessment using theoretical models incombination with information from tests
    • Methods for reliability analysis of wind turbines
    • Methods for reliability analysis of wave energy devices

    Prerequisites: Basic knowledge on probability theory and statistics.
