Large Turbine Guidelines Subcommittee:
Next Meeting
The next in-person meetings of the subcommittee and the project teams are currently scheduled for all day Monday, October 4. However, the first event of the AWEA Offshore Workshop will be the opening reception at 4 p.m. Eastern on Tuesday, October 5. Therefore, the leadership of the subcommittee and the project teams concur that the meetings should be held on Tuesday instead.
AWEA Standards Coordinating Committee
Subcommittee on Large Wind Turbine Permitting Guidelines Meeting
2010 October 05
08:00 – 16:00
Atlantic City Convention Center
One Convention Boulevard
Atlantic City, NJ 08401
Phone: 609-449-2000
More details will be sent when they are available. It is not necessary to attend the Workshop in order to participate in this meeting. To register for the workshop, please visit the AWEA web site.
Name Change
The subcommittee is being asked to consider a name change. When the subcommittee was considered by the AWEA Standards Coordinating Committee in May of 2009, the intent was to investigate the process in the U.S. for complying with equipment quality assurance requirements of the financial community and insurers and to receive building permits from local Authorities Having Jurisdiction (AHJs).
The shorthand phrase that was used in the establishment of the subcommittee was “permitting guidelines” – guidelines on how to get equipment permitted. However, the name of the standards group, “Large Wind Turbine Permitting Guidelines,” has been interpreted by people outside of the standards community as an effort to address siting issues – for which permits are also issued.
To avoid further confusion in the broader wind community, I suggest that we recommend to the Standards Coordinating Committee that the name of the subcommittee be changed to “Large Wind Turbine Compliance Guidelines” – i.e., compliance with conditions required to receive permits. Actually, I believe that this non-substantive matter can be handled by Suzanne Meeker, the new chair of the Standards Coordinating Committee, who is copied on this note. Unless subcommittee members or leadership have other suggestions, the subcommittee chair, Sandy Butterfield, can make the request to Suzanne on behalf of the subcommittee.

Dear AWEA/ASCE Structures Project Team:
The leaders will be sending me the latest draft of their sections later this week. Please provide them any assigned input you had on Wednesday or Thursday. I will be working all this week on this document and on Friday (July 30th) I will re-assess the current status of the Draft document and communicate with you all again in this regard.
Sandy Butterfield, John Dunlop, Jim Rossberg and I met with the Canadian folks leading the effort to adopt CSA/IEC 61400 into their existing building codes. A brief summary note about our meeting follows. They have acknowledged with appreciation our great effort to reconcile existing IEC 61400-1 with U.S. building codes, especially as they relate to IBC. U.S. and Canada will continue interchanging ideas and updates about our progress with the Guide. In fact, they are expecting a copy of our draft document as they still need to see what gaps remain to be solved in their existing CSA/IEC and their building code NBCC. They have found, on the other hand, that their building code needed a change in the definition of “Building” such as to include wind turbines. By doing this as an amendment to NBCC they have gained momentum towards an adoption of CSA/IEC into their code.
As for the U.S. counterpart we are targeting adoption of a U.S. Standard in the International Building Code (IBC). We currently have no issues for the definition of “buildings” as IBC is focused on “structures” and already has a Chapter for “Special Construction” that is being considered for potential referencing. Please note that IBC would not reference a Guide as it is not mandatory. ASCE has committed to help us through this process more effectively beginning this Fall 2010. The following, then, seem to be a mid- to long-term goal of our team effort.
The above plan is tentative and I would be happy to hear your input/comments. We will review/discuss during our next telecom in August 12. If you have any questions don’t hesitate to contact me.
Please note that our meeting in Atlantic City has been changed to Tuesday, October 5.
Kind regards,

Dear AWEA/ASCE Structures Project Team,
Please find attached the latest meeting minutes from the August 12 teleconference. Please provide any comments to the meeting minutes to our Secretary Leonardo Dueñas (leonardo.duenas-osorio@rice.edu) before our next meeting on September 16th.
As an update to the most recent discussions please see the attached meeting minutes…
In short,
It does not seem like a normative Standard is wanted or possible for inclusion into IBC in the near future (this makes me think that a U.S. normative Standard would not be anticipated before 2015-2020).
The non-mandatory Guideline we are working is expected to be used a general tool by Authorities Having Jurisdiction, Designers, Inspectors, etc. to guide the process in how the normative existing U.S. and International Standards apply to wind energy structures.
To position the industry to develop a Standard in the future, ASCE is considering to initiate a Task Committee to address the existing (i.e. not completely “solved”) challenges that will be presented in our Guide. The ASCE Task Committee expects to produce one or more State-of-the-Art reports that intend to expand upon and discuss the technical difficulties/differences of national and international Standards. This Task Committee is being formulated and led by the Chair of ASCE Wind Energy Structures subcommittee Jomaa Ben-Hassine. The existing Guide development has priority over this Task Committee, but as you find time to contribute to the efforts in ASCE please do so.
A MOU or other type of agreement is still being discussed to articulate how the present Guide being developed by the joint AWEA/ASCE subcommittees becomes in fact a joint released document by AWEA and ASCE.
Kind regards and Thank you.

AWEA Structures Outreach Summary for Groups.pdf (175 KB)
Dear Kevin and team,
I believe you have the right list, in any event I am cc’ing the Yahoo group and anyone who didn’t receive 2 emails from me today should notify me.
Kevin et al.
You have done a good job at synthesizing this information. I encourage you all to review these results on your own and create an independent view of the same to be shared in our next meeting. The following are some of the comments and (seemingly obvious) questions I will have for you all next time.
Comment 1: I’m aware of the internationally-recognized stds. but survival wind speeds are a problem for otherwise appropriate turbines for this region (Class II/III) due to potential hurricane exposure.
Question 1: Does our Guide address this issue? How will it be addressed? Can anyone provide further input? Comment 2: The IEC/EN standards are performance related and specifically state that they are only for protecting the multimillion dollar investment of the buyer = they have NOTHING to do with “safety”
Question 2: Is this true? What “safety” are they referring to? Doesn’t IEC 61400-1 state that structural, mechanical and electrical safety of these systems is covered by the same Standard? Comment 3: Permitting is similar to other towers and stand-alone structures.
Comment 4: And this is not good for large vibrating structures
Question 3&4: If permitting of wind turbines is done as for towers and stand-alone structures, and this is not good for large “vibrating” structures, will our Guide provide the necessary interface of knowledge between standards for tower/stand-alone structures and “new” international Standards for wind turbines? Comment 5: My staff is fully trained and certified to make the necessary code related decisions and observations. Our biggest trouble is with the owners, engineers, and contractors involved in these projects and their lack of understanding of the codes and their lack of plannign and coordination.
Question 5: Will our Guide provide enough information or help “owners, engineers, contractors” regarding their understanding of codes, planning and coordination? Do/Can/Should we provide solutions to all these?
Comment 6: Your qeustions seem geared to achieve a particular answer.
Question 6: Can somebody review our survey questions and see if they all seem geared towards a particular answer? Comment 7: PERMITS ARE ISSUED BASED ON REVIEW BY A CERTIFIED STRUCTURAL ENGINEER.
Comment 8: Wind turbine structures are designed and permitted on aperformance based design for the entire installation as required by the statewide buildign code.
Question 7&8: If permits are issued based on review of Certified Structural Engineer and wind turbines are designed and permitted on performance-based design…. Are these structural engineers working for the manufacturer or all the independent structural engineers who provide review perform a “performance-based” analysis? Comment 9: If vetted through the ICC code review process
Question 9: Should our Guide be vetted through the ICC code process? What can we do better to create more trust in our consensus-based Guide developed under the AWEA/ASCE umbrella? Comment 10: THE APPROVALS NEED TO COME FROM WITHIN THE UNITED STATES BY US TESTING AGENCIES, US ENGINEERS AND US CODES, NOT JUST WITHIN THE “INDUSTRY”
Question 10: What approval are they referring to? Really? Why? Kind regards and Thank you.

[LgTurbineStructures] AWEA/ASCE Survey Key Questions for Discussion Today
REVIEW OF SURVEY QUESTIONS
Questions sent previously attached below for convenience.
Dear Kevin and team,
I believe you have the right list, in any event I am cc’ing the Yahoo group and anyone who didn’t receive 2 emails from me today should notify me.
Kevin et al.
You have done a good job at synthesizing this information. I encourage you all to review these results on your own and create an independent view of the same to be shared in our next meeting. The following are some of the comments and (seemingly obvious) questions I will have for you all next time.
Comment 1: I’m aware of the internationally-recognized stds. but survival wind speeds are a problem for otherwise appropriate turbines for this region (Class II/III) due to potential hurricane exposure.
Question 1: Does our Guide address this issue? How will it be addressed? Can anyone provide further input?
Comment 1 should be considered in conjunction with whether or not the document we are developing will require certification of the turbine, and therefore development of the system loads, per IEC. If so, certification per the IEC standard should include design for maximum wind speed in site-specific events like hurricanes if necessary, with design to include turbine active yaw, which is understood to reduce combination of peak wind load with static moment. Tornadoes may not be covered, however. Our loads section should identify that turbine manufacturer loads are produced per an existing standard (IEC) utilizing the proprietary knowledge required to define / determine the electromechanical and aerodynamic interactions of turbines with different wind conditions (drag coefficients, angle of attack of wind, etc). Local engineers will not be able to utilize only ASCE-7 (for example) without direct employ of turbine manufacturers as turbine loads in wind are not (as indicated) JUST dependent on wind.
I agree with Mr. Moller’s comments. IEC has a wind turbine class S design for extreme wind conditions. Unlike ASCE (or similar) codes, it considers fatigue life. Local Engineers following ASCE (or similar) will be gauging single-event survival (less stringent) without the benefit of proprietary knowledge and consistency.
Comment 2: The IEC/EN standards are performance related and specifically state that they are only for protecting the multimillion dollar investment of the buyer = they have NOTHING to do with “safety”
Question 2: Is this true? What “safety” are they referring to? Doesn’t IEC 61400-1 state that structural, mechanical and electrical safety of these systems is covered by the same Standard?
The basis of the comment is not clear, plus we are not readily familiar with all aspects of IEC/EN.
IEC does direct that the “appropriate” personal safety be used during construction, erection, commissioning, service etc. It does not give specific safety guidelines as those vary from region to region – or state to state for that matter. Comment 3: Permitting is similar to other towers and stand-alone structures.
Comment 4: And this is not good for large vibrating structures
Question 3&4: If permitting of wind turbines is done as for towers and stand-alone structures, and this is not good for large “vibrating” structures, will our Guide provide the necessary interface of knowledge between standards for tower/stand-alone structures and “new” international Standards for wind turbines?
It is not clear what Comment 3 refers to, i.e. design and associated review, or some other aspect of permitting, however we must admit not being familiar with e.g. transmission or radio tower design standards. Relative to wind turbines, it is as simple as requiring adherence to an existing standard for the turbine / tower loads assessment, production of both ultimate strength and fatigue limit state design scenarios, and requiring thorough (e.g. complete load path for fatigue and ultimate) tower / foundation design for each. The loads are EVERYTHING; development of them is discussed above.
The comment is not clear to me either.
Comment 5: My staff is fully trained and certified to make the necessary code related decisions and observations. Our biggest trouble is with the owners, engineers, and contractors involved in these projects and their lack of understanding of the codes and their lack of plannign and coordination.
Question 5: Will our Guide provide enough information or help “owners, engineers, contractors” regarding their understanding of codes, planning and coordination? Do/Can/Should we provide solutions to all these?
Without knowing what area of code compliance review the respondent specializes it’s difficult to comment, however addressing the comment may be a local issue, something that the guide probably can’t address. The comment also sounds like whining.
This sounds like it comes form an AHJ who insists on enforcing building codes even when they don’t make sense. A note in the guide that these are not buildings or subject to are subject only to applicable codes would be helpful. Comment 6: Your qeustions seem geared to achieve a particular answer.
Question 6: Can somebody review our survey questions and see if they all seem geared towards a particular answer?
The questions seem fair.
Comment 7: PERMITS ARE ISSUED BASED ON REVIEW BY A CERTIFIED STRUCTURAL ENGINEER.
Comment 8: Wind turbine structures are designed and permitted on aperformance based design for the entire installation as required by the statewide buildign code.
Question 7&8: If permits are issued based on review of Certified Structural Engineer and wind turbines are designed and permitted on performance-based design…. Are these structural engineers working for the manufacturer or all the independent structural engineers who provide review perform a “performance-based” analysis?
Comment 7 seems to say that the author is not familiar with the code classification (i.e. non-building) of turbines for structural permits and is satisfied knowing that a structural engineer is doing the review, which may not always be true. The definition of “performance-based” design for a given structure is highly dependent on criteria. Insofar as the code sets criteria for non-building structures related to strength it establishes performance requirements for turbine foundations – but this is less than half the story as dynamic stiffness and fatigue requirements are not covered in the code but are at the fore of criteria derived from turbine needs. The tower and foundation structural engineers have historically had to determine how to come to this without the benefit of US standards, often against their will.
These are typically independent engineers – the guide should be moot as to who hires them as this is a commercial matter,
Comment 9: If vetted through the ICC code review process
Question 9: Should our Guide be vetted through the ICC code process? What can we do better to create more trust in our consensus-based Guide developed under the AWEA/ASCE umbrella?
Does the ICC have a code review process for other than of their own codes? We have aligned the guideline with IEC, the body that has authored standards to which the turbines are often certified using defined wind classes and turbine operational states (=> loads) that also fall under IEC. Technical committee 88 of the IEC authors the relevant documents in wind iec.ch/dyn/www/f?p=102:7:0:: … RG_ID:1282. By producing a document that marries the preeminent international standard (with its inherent reliability framework around loads pegged at 20-year life) to a standard or standards for structural design aimed at US compliance may very well provide the connection needed between the world of turbines (IEC) and the world of US building codes (IBC, ASCE, ACI, AISC, etc). Fatigue design requirements would need to be folded into this, however, and there is more available through reference to standards from other countries than US standards (unfortunately).
Comment 10: THE APPROVALS NEED TO COME FROM WITHIN THE UNITED STATES BY US TESTING AGENCIES, US ENGINEERS AND US CODES, NOT JUST WITHIN THE “INDUSTRY”
Question 10: What approval are they referring to? Really? Why?
The comment appears to be utilizing “approval” to replace “consensus” from the survey question “…consensus within the industry on code provisions, safety margins, and design life…” The comment also appears to not recognize that US engineers are preparing the guideline and that US codes are the basis of the guideline, supplemented by international codes as necessary.
Is he talking about certification (DNV, GL…)? Kind regards and Thank you.

Large Turbine Compliance Guidelines Subcommittee - PLANNING MEETING SEPTEMBER 3
Group,
Here is a nice gift basket for your Labor Day weekend. Included are the minutes that Lars recorded from our last call, the original document outline, our contact list and an e-mail regarding the agenda for the AWEA meeting next month. Per our last discussion, I would like to have final comments on the main sections headings, included both on the minutes and on the outline spreadsheet, within the next 2 weeks. Don’t worry too much about the sub-sections that are shown on the spreadsheet; we will leave that up to the section leads to finalize and we can collect those comments later. I left that information on the spreadsheet since several of you had asked and I thought it would be helpful to recap the original logic as you consider any comments that you may have on the main sections. In conjunction with any comments that you may have, please also indicate your ability to contribute either as a lead author, contributor or reviewer in any of the sections identified. I know that it would be better to compile comments, adjust the sections as needed, and then ask for this identification but we need to short cut the process a bit. My hope is that we have the final sections and allocations of leads identified prior to our next call so that we can begin to have more topically focused discussions.
Lastly, please let me know if you intend to attend the meetings on Oct 5th in Atlantic City.
Please note the following issues and events relevant to the Subcommittee:
Name: SCC Chair Suzanne Meeker concurs that we should discontinue using the term “permitting” in the subcommittee name. Please use the current name of the subcommittee: Large Turbine Compliance Guidelines Subcommittee
Leadership: Sandy has resigned as the Subcommittee chair. Suzanne has accepted the recommendation to appoint Paul Veers as the new Subcommittee chair, and Paul has accepted.
Subcommittee Meeting: The next meeting of the Subcommittee will be on Tuesday, October 5, in Atlantic City, NJ from 9 a.m. to 5:30 p.m. We will have three separate rooms available throughout the day, each with AV equipment. The opening reception for the Off Shore Workshop will be held that day from 4 – 7 p.m. Information on the conference, logistics and lodging is available at: offshorewindexpo.org/.
Draft agenda for October 5 meeting:

All,
I have had few responses to my e-mail. We have a call scheduled for next Tuesday which will then be followed two weeks after that with the meetings at AWEA. I would really like to have input from everyone in the group this week so that I can compile data and be in a position to present a plan to go forward next Tuesday. To re-cap, I am looking for the following from each of you.
• final comments on the main sections headings
• indicate your ability to contribute either as a lead author, contributor or reviewer in any of the sections identified
• if you intend to attend the meetings on Oct 5th in Atlantic City
If you have no comments on the headings or do not intend to contribute to the document please indicate as such.

6. Contact industry associations (ACI, AISC, ANSI, etc.) and ask for review of the consensus-based Guide.
7. Reconcile additional comments from associations and the public
8. Submit to AWEA/ASCE Standard Committees for consideration and approval.
9. Release Guide in First-Quarter of 2011.
For those also participating in ASCE Wind Energy committee, I recommend to focus in producing the above-mentioned AWEA/ASCE Guide, then any missing elements or unsolved issues of the Guide can be addressed by the ASCE Task Committee that is being formed.
See you all in Atlantic City in October 5th. I will send again the invite to this next week, including our agenda and action plan.
Kind regards and Thank you.
