Integrity And Corrosion Of Offshore Wind Structures

Integrity and Corrosion Of Offshore Wind Structures

Day 1 - Tuesday 2 June 2015

08:30 Registration And Morning Refreshments


09:00 Chair's Opening Remarks:
What have We Learnt About Applying Solutions To The Offshore Wind Environment?

Trevor Osborne, Past President, Institute Of Corrosion (ICorr)


09:20 EDF Energy Case Study:
Experiences Of Internal Corrosion Protection For Offshore Wind Monopile Foundations

• Issues that were faced within the internal monopiles
• Results of the CP survey, corrosion coupons and gas sensors from the site
• Chemical reactions caused by cathodic protection inside the monopile and its impact on the behaviour of the steel
• Future plans for long term corrosion monitoring experiments

Claire Canning, Offshore Wind Research Engineer, EDF Energy

Which Electrical Protection Solutions Are The top Performers?

10:00 Panel Discussion:
ICCP Systems: Weighing Up The Benefits And Concerns 

• How are existing ICCP systems performing on wind farms?
• What has been the experience of installing ICCP systems? What has gone well and what were difficulties have been encountered?
• How does ICCP affect coatings? Is this dependent on how far the devices are turned up? What are the guidelines on this issue?
• Is there a relationship between corrosion protection of offshore wind structures and the corrosion of vessels entering a site that uses ICCP?

Panellists include:
Frits Verbruggen, Chief Of Field Sales, Corrosion & Water-Control bv

Gro Østensen Lauvstad, Principal Engineer - Corrosion And Materials, FORCE Technology


11:00 - Networking Break And Morning Refreshments -

11:30 Cathodic Protection Of Monopiles In Deeper Water: What Are The Challenges?

• What solutions can be considered to ensure the corrosion protection of monopile internals/externals in deeper water?
• What are the economics and benefits of applying coating?
• What can be gained by CP monitoring and inspection?

Gro Østensen Lauvstad, Principal Engineer - Corrosion And Materials,  FORCE Technology

The Future Direction Of Coatings Use In The Offshore Wind Industry

12:00 The Viability Of Using Aluminium, Zinc And Copper Coatings For Offshore Wind

• What guarantees do we have that this will last for the lifetime of the structures?
• What if these coatings are damaged? Can they still protect offshore structures?
• Performance experiences from the Offshore industry
• Is it commercially viable? Or are these options only feasible for sites that have a particularly high corrosion risk?

Dr Shiladitya Paul, The Welding Institute (TWI)


12:40 - Networking Lunch -


13:40 Coatings: What Have We Learnt About Applying Them To Offshore Wind Farms?

• What have been the lessons learnt about the application of coatings to internal and external surfaces on monopiles and jackets?
• Are coatings really being damaged during installation or is this an empty concern?
• How long are different coatings lasting on offshore wind farms?

Clare McDermott, Business Development Manager Renewables, Azko Nobel 


14:20 A New Testing Tool For MIC: What Problems Will It Solve?

• What are the current possible methods for monitoring and testing for MIC or MIC risk?
• Reflection on the research, development and testing that has gone in to the new MIC testing solution
• How does the testing equipment work on a practical level and how accurate are the results?

• What are the remedial actions that can be taken for MIC once it has been diagnosed at a site? How effective are they?

Oliver Kranz, Chemist, Fraunhofer IWES


15:00 - Networking Break And Afternoon Refreshments -


15:20 Experiences With Monitoring And Inspection Of Corrosion In Offshore Wind Foundations

• What are the key corrosion risks? An exploration of macro galvanic elements, MIC and HISC

• How can effective inspection techniques, including visual and UT, aid in preventing corrosion?

• An assessment of CP surveys; drop cell, environmental depth profiling

• Exploring the various monitoring techniques; coupons, full-length coupon, potential, ER

Troels Mathiesen, Corrosion Specialist, FORCE Technology


15:50 Interactive Whole Room Discussion:
Which Solutions Will Ensure The Lifetime Of Offshore Structures And Bring Down LCE?

• Which systems will survive the 20 – 25 year lifetime of the wind farm?
• What kind of impact each solution will have on the design of structures and how will it affect CAPEX and project timescales?
• Calculating the LCE of each system, looking at both CAPEX and OPEX over life

Led by: Trevor Osbourne, Past President, Institute Of Corrosion (ICorr)
