Task 33 Navigation

Welcome to Task 33 Work Plan

Subtask I: Experience
In terms of reliability, the use of experience is indispensable. Subtask I Experience is therefore a cross-section task and affects both Subtask II Data Collection and Subtask III Data Analyses. Comprehensive work and research have already been conducted to gather and compare different failure statistics and approaches used in various research activities. The experience gained from these failure statistics will be used to plan future work. Experience from other industries like the oil and gas industry or the automotive sector will also be considered (e.g. the OREDA-database). This task should process and present experience regarding data collection and analyzing tools from related as well as from the wind energy sector itself. Valuable findings will then be transferred and implemented in the overall structure of data collection and analyses. 

Subtask II: Data Collection
This Subtask comprises different aspects of data collection. Basic requirements of the right set of reliability relevant data need to be defined. Therefore, an agreement on necessary data (e.g. core‑, in-service-, event data) is required, whereby the flow of maintenance information needs to be considered and taken into account. The development and implementation of standardized designation systems is another main focus of this task. International standards like the adopted component designation system RDS-PP as well as national efforts of providing guidelines, e.g. the Technical Guideline “Maintenance of wind turbines” (Technische Richtlinie TR 7 “Instandhaltung von Windenergieanlagen”) from the Federation of German Wind Power FGW (Fördergesellschaft Windenergie und andere Erneuerbare Energien), need to be developed further to a stage where they find application. Comprehensive efforts have recently been undertaken to agree on e.g. RDS-PP and the implementation of such designation systems (standards) have to take place globally.

In Subtask II all participating institutes will contribute information from recent activities to identify different development directions and collaborate on a state of the art data collection strategy for reliability analyses. Participants will establish contacts with operators, manufacturers, and other industries to get a wide input and dialogue. This task can benefit from the results of several projects such as Reliawind, Sandia CREW database, Offshore~WMEP, EVW, VTT statistics, etc. as well as from different working groups for standardization such as VGB Powertech, RDS-PP Fast Track User Group, FGW, etc. Additionally this Subtask needs a strong trade-off with Task III (Data Analyses) for defining a necessary (for suitable analyses), but also possible (regarding the data collection efforts) level of detail of collected data.

Subtask III: Data Analyses
The main objective of Task 33 is to identify the most valuable O&M tools in the market. In this subtask, participants will determine and commit to a level of analyzing detail. An agreement on type and scope of future O&M tools will be considered, which includes the definition of possible and convertible reliability analyses. The interaction between Subtasks I and II are important for the defined Data Collection and the level of detail, that are of great significance for a successful realization of preparing recommended practices. Demands and requirements of reliability data for O&M tools define the level of detail for relevant data. In addition, the complexity of maintenance information from various locations will have an effect on the degree of analyzing opportunities.

In the entire process and task duration, the possibilities of sharing information both in terms of data and analyses will be discussed. More transparency and confidence in the overall goal of defining a standardized data structure will encourage sharing and merging information. This is necessary to conduct sound and purposeful analyses.

The competences gained in the IEA Task 33 will be collected and summarized in an IEA “Recommended Practices for Reliability Data”.
