Monitoring Of Offshore Wind Structures: Standards And Developments
09:40 What Are The New Developments In Structural Monitoring Systems?
• Reliability and long term performance, experience from installed monitoring systems. What can be expected?
• Linking foundation monitoring data to environmental data (wind, temperature, tide and waves), through practical examples
• Instrumentation below the water line - difficult or just a matter of experience?
• What can we do with monitoring data?
• Understanding new developments including in-situ monitoring of grouted connections and strain measurements to make use of optical fibre
Per Sparrevik, Expert Adviser,
Norwegian Geotechnical Institute (NGI)
10:20 Parkwind Case Study:
Monitoring The Corrosion And Integrity Of Offshore Wind Structures
• From an operator and project developer point of view, what are the opportunities, costs and technical drivers for monitoring?
• What are the critical parameters being monitored?
• What have we learnt about design and O&M optimisation from three years of monitoring?
• Why fatigue and lifetime assessment is a crucial decision support parameter
Cedric Van Den Haute, Foundations Engineer,
Parkwind
10:40 - Networking Break and Morning Refreshments -
11:10 Structural Monitoring: What To Monitor And How To Transform Data Into Information?
• What are the basic and specific monitoring solutions implemented at Belwind phase 1 and NorthWind?
• What is the reliability of these systems and what kind of data is coming from them?
• How to transform this data into useful information for improved design calculations and O&M optimisation
• What is the influence of the operational and ambient conditions on the fatigue and lifetime of offshore wind turbines?
• Can we translate findings from one turbine or one site to another turbine or site?
• Combining long term monitoring with short term measurements for improved decision support
Christof Devriendt, Scientific Research Coordinator,

11:50 Panel Discussion
What Is Emerging As Standard Practice In Remote Monitoring And Measurements For Foundations?
• What are other companies monitoring and how are they turning the data into useful information?
• What stresses, strains, and acceleration are these systems showing us?
• What is happening to structures under certain loading conditions?
• Do we need an industry standard for Offshore Wind? Is this technically feasible?
• Gaining buy-in from certification bodies, regulatory authorities and insurers

12:40 - Networking Lunch -
Ensuring Integrity In The Design And Manufacturing Phases
13:40 Improved Fatigue Crack Growth Models Taking Into Account Load Sequence Effects
• The performance of the new fatigue model which can lead to a 25% - 50% longer design life for fatigue critical parts
• The probabilistic model to determine improved inspection intervals without jeopardising safety and operational availability
• Details of extensive laboratory tests to validate models for corrosive and non-corrosive environments
Sjoerd van der Putten, Structural Dynamics Project Manager,

14.10 Monopile Design: Overview Of The PISA Project
• Trends towards deeper water and larger turbines
• Current design approaches for monopiles and their limitations: opportunities to reduce conservatism
• An overview of research output from the PISA Project and the implications for monopile design
Dr Byron Byrne, Professor of Engineering Science,

14:50 - Networking Break and Afternoon Refreshments-
15:10 In-Depth Update: Maximising Lifetime Asset Integrity Study
• What were the main lessons learnt from the study?
• Potential improvements to lower costs and avoid structural issues
• CAPEX versus OPEX: which is the best approach for achieving the predicted lifetime and lowering LCE?
Marc Costa Ros, Senior Manager, Offshore Wind,

16:00 Microbiological Influenced Corrosion (MIC): Assessing And Reducing The Risk
• MIC, a significant risk for our industry?
• Is prevention of MIC already a part of the planning and design of new structures? Should it be?
• An overview of methods and strategies for reducing the risk of MIC
Dr Nanni Noël, Research Scientist, Microbiology,
Endures
16:40 Wrap Up Discussion:
Major Lessons Learnt And The Implications For The Industry Going Forward
• What are the main lessons learnt from existing wind farms across Europe?
• How can we share knowledge better in this area in terms of ongoing research, R&D and industry or government initiatives?
• What are the implications for the design life of offshore wind structures and how will it impact possible repowering options, life extensions and decommissioning plans?
