Day 2 - Wednesday 3 June 2014

Chairs Opening Remarks

Adrian Fox, Programme Manager Supply Chain and Technology, The Crown Estate

Monitoring Of Offshore Wind Structures: Standards And Developments

Parkwind Case Study:
Monitoring The Corrosion And Integrity Of Offshore Wind Structures

• What are the opportunities, cost and technical drivers for monitoring from an operator and project developer point of view?
• What are the critical parameters being monitored?
• What lessons have we learned from three years of monitoring towards design and O&M optimisation?
• Why fatigue and lifetime assessment is a crucial decision support parameter

Cedric Van Den Haute, O&M Package Manager Foundations And Cables, Parkwind

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, OWI Lab

What Are The New Developments In Corrosion And Structural Monitoring Systems?

• What independent reliability trials have been carried out on existing systems?
• Should we be linking foundation monitoring data to environmental aspects such as sea tidal movement, temperature and the seasonal evolution of microbial activity?
• What’s next? Can we integrate observations from onsite staff into the system?
• What can we do with monitoring data? Can it replace design calculations?

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

Panellists Include:
Dr Feargal Brennan, Director of Energy, Cranfield University
Christof Devriendt, Scientific Research Coordinator, OWI Lab

- Networking Break And Morning Refreshments -

Ensuring Integrity In The Design And Manufacturing Phases

Designing Structures For A 25 Year Lifetime And Reduced O&M Expenditure

• Defining the critical areas to prevent corrosion and decay
• Prevention of corrosion by appropriate structure design
• Which third parties should be consulted in the design review to reduce the risk of error?

SLIC Project Update: Future Fatigue Design Guidance And Standards For Offshore Wind

• The aims of the Structural Lifecycle Industry Collaboration (SLIC) project
• Preliminary results from the pre-testing phase where tailored methodologies were
developed through small scale testing programmes
• When will the guidance be finalised and what is its likely scope?

- Networking Lunch -

Optimising Structures To Reduce The Cost of Materials: How Will This Affect The Lifetime?

• Integrated design of turbine and foundation: what is the best model for getting the WTG and foundation OEMs to work together on the design the process?
• How much can we realistically optimise using SN curves and the available modelling tools?
• Making use of information from structures of our existing sites to benefit new designs
• Is this a safe option or do we need the additional metal to allow for corrosion?

Dual Perspective
Do We Need To Lift Fabrication Quality Standards To Prevent Corrosion And Integrity Problems?

• What are the current controls on and training of welders? Does this need to improve?
• Should manufacturers and clients work more closely together to ensure specifications are met?
• How can we join up construction with O&M to take lifetime costs on board in the early stages?

- Networking Break And Afternoon Refreshments -

New Research Into Corrosion And The Marine Environment

Microbiological Influenced Corrosion (MIC): Assessing And Reducing The Risk

Microbiological Influenced Corrosion (MIC): Assessing And Reducing The Risk
• MIC, a significant risk for our industry?
• Prevention of MIC already as a part of planning/ design of new structures?
• Overview of methods and strategy
• Are we designing structures to avoid MIC? Should we?

Dr Nanni Noël, Research Scientist, Microbiology, Endures

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?
