Knowledge Transfer and Challenges of Emerging OWF Markets
Emerging Markets OWF Projects – What can we learn
Development in the OW industry has seen drastically reduced LCoE over time in more developed markets
Can we have the same reduced LCoE in Asian region on day one?
What are the local challenges?
What can we learn from previous mistakes and knowledge gains made in existing markets?
Knowledge Transfer During Concept Design
• Wind farm concept design to achieve
minimum levelised cost of energy (LCoE)
is a multi-variable design optimisation
problem which requires a broad view over
many technologies:
• Influence of turbine on support structure design
• Energy yield assessment
• Design of electrical infrastructure
• Installation methods
• Operations and maintenance
• Etc.
• Pre-FEED studies informed by a reliable
cost-model and prior project experience
can repay their cost many times over.
Knowledge Transfer During Turbine Engineering/Selection
• The wind turbine is the single most influential component in an offshore wind farm:
• CAPEX typically responsible for 40% of levelised cost of energy (LCoE)
• Most significant source of structural loads
• Responsible for ALL of the revenue!
• Experienced independent technical review of the turbines can provide project efficiencies and help to:
• Understand energy yield for turbine position optimisation & assessing performance in operation;
• Understand reliability of technology when selecting turbine model;
• Understand dynamic interaction between turbine & support structure in order to design most cost effective support structure;
• Understand condition of components at end of warranty period;
• Understand condition of turbine & support structure when assessing lifetime extension options.
Knowledge Transfer – Operating Environment
+ =
BUT......
Normally….
Asian OWF Technical Challenges – Environment
What about too much wind? What about earthquakes?
or
Knowledge transfer from the Oil and Gas industry that
have been operating in similar
offshore environments for
decades essential both from a design
perspective but also from an
installation and operations perspective
New Market – Technical Challenges – Standards
Contractor Procedures and Equipment Standards
International Market has seen continual improvement for over a decade
No need to re-invent the wheel every time a new regional market is entered
Asian OWF – Installation Vessels – Heavy lift vessel or jackup?
• Assets availability in the region?• O&G offshore heavy lift vessel or barge with lifting capacity but no deck space
• Shear leg
• Extensive O&G experience in transportation & installation but no renewable experience
• Regional operational limitation?• Weather condition (typhoon and monsoon)
• Earthquake and soil liquefaction
• Water depth
• Bottom fix or floating
Asian OWF – Installation Vessels – Heavy lift vessel or jackup?
We should share our knowledge
• Create awareness within O&G contractors on specific renewable constraints
• Assist developers in assessing existing asset suitability and operability
• Convert, upgrade, reconfigure assets that suits regional specific renewable requirements
• Adjust best practices to regional specific operational requirements
Asian OWF – Installation Vessels – Cable Laying Vessel?
• Assets availability in the region?
• Barges not meeting class and international standards with limited operability
• Large O&G offshore cable and pipe layer (availability, price )
• Number of offshore vessel ready for mobilization (MPV, OSV …)
• Number of flat top barge candidate for conversion with yard availability
• What are the operational differences with Europe?
• Limited experience to large diameter export power cable operations
• Different installation practice
• Limited documentation (operation philosophy, engineering studies)
• Survey requirements
Asian OWF – Installation Vessels – Cable Laying Vessel?
We should share our knowledge
• Share best international installation practices – to avoid losses
• Re-use and upgrade vessel when possible
• Help Balance operability versus cost
Emerging OWF Market Challenges – Re-inventing The Wheel
Challenges...... Education is down to knowing the
unknow unknowns ……….• Lack of country based regulations enforcing
minimum standard.
• Local power Co(s) not used to operating in
Marine Environment.
• Local Contractors not used to working in OWF
projects or in some cases even offshore.
• Local Vessel operators not used to working to
international offshore standards

• Large project being developed in short time
frame, contractors need redundancy in local
supply chain but also qualified people
Case Study – Cable Layer Design – Taiwan
• Initial assessment:
• Compliance with class and standards
• Equipment review
• Advise on upgrade scope of work and cost
• New build basic design:
• Compliance with class and European Developer standards
• Back deck layout based on European best practice
• Equipment supplied from Europe and Asia
• Regional construction
• How did we transfer our knowledge?• Create awareness of operational limitation
• Supply highly technical expert to explain “how” and “why”
• Do not perform on behalf but assist and educate
• Stand in our client shoes instead of ours
• Development of Installation Procedures
Case Study – Cable Installation Analysis Training – Taiwan
• Develop understanding of offshore wind farm related operations.
• Develop analytical skills to model those operations.
• Support through: practical examples; training workshops; real case studies.
• Goal to be able to provide analysis to be approved by MWS.
• Develop Taiwan offshore operations analysis skills.
• How did we transfer our knowledge?
• Explained operation and the analytical aspect
• Developed local resources that can assist the industry going forward
Case Study – Knowledge transfer in Foundation Design
• Assisting Chinese design institute by providing support for WTG
foundation jacket design for a 1.2 GW project.
• Support consists into:
• Supply of INNOSEA PREDIN software tool, dedicated to the design of offshore wind
foundations.
• Training of Client’s team
• Software customization to Client’s specific needs
• Independent jacket design (FEED stage)
• Review of Client’s in-house jacket design and optimization analyses.
• How did we transfer our knowledge?
• Explain the specific turbine loads and cyclic loading which most traditional offshore
foundations do not consider.
• Supply highly technical experts to explain “how and “why”
• Do not perform on behalf of but assist and transfer our knowledge
Case Study – Knowledge Transfer in Floating Wind
• What knowledge may be needed?
• Awareness on the limitation in coupling aeroelastic and
hydrodynamic models which is new to the offshore floating
industry
• Turbine suppliers and floater designers need to share design
information not to constraint the design cycle
• Contracting independent consultants who can interface
between parties
• What has LOC group been doing?
• Development of a software package allowing the integrated loads assessment for floating wind turbine, by linking Orcaflex software to Siemens-Gamesa in-house aeroelastic software (BhawC).
• Implementation of a numerical framework in line with the aeroelastic code mathematical theory and OrcaFlex requirements
• Development of a pre-processing tool allowing the WTG supplier to automate the creation of OrcaFlex input files for integrated load assessment loop.
Why should we all transfer our knowledge
• Because we don’t want to repeat the same mistakes
• There will be cost saving by sharing knowledge
• Project risk can be decreased
• Projects delivered in time with no LTI
• By helping others, the regional market will take-off faster and we will all benefit from it
Because climate change is happening and
continued OFW development is needed in Asia!
