1 Technology Implementation Design, Construction, Materials, and Welding Technology Track at R & D Forum Yong-Yi Wang Engineering Mechanics Corporation of Columbus 3518 Riverside Drive, Suite 202 Columbus, Ohio ext. 230

2 2Implementation by Yong-Yi Wang What is Implementation? n Put technology to field practice u Codes and standards u Hardware u Software u Publications u Internal use by operators

3 3Implementation by Yong-Yi Wang Threats and Opportunities n Threats u Outdated codes and standards F For instance, some codes are so out-of-date that companies may not use them or even participate committee activities u Weak link among universities, national labs, research institutes, and commercial entities u Gap of talents and knowledge n Opportunities u Risk-based design and maintenance u Computational/software tools

4 4Implementation by Yong-Yi Wang Code Activities (Limited Scope) n ASME u Reliability-based design and assessment (RBDA) F Based on PRCI-funded work at C-FER F Establish target reliability for different failure modes F Target reliabilities calibrated to current industry practice n ISO u Reliability based limit states design (ISO 16707) n API u 1104 n CSA u Reliability based limit states design u Strain based design u Revision of CSA Z662 Appendix K n OPS/MMS sponsored work n Not covered here: NACE, AWS, ASTM

5 5Implementation by Yong-Yi Wang DOT/PRCI Project on Weld Code Revision n An example of code implementation (commercialization) u Targeted specific codes from the start u Clear deliverables and schedule u Involvement of industry through public meetings and code committee activities n Develop deterministic ECA procedures that would form the basis of code revisions for API 1104 Appendix A, and other ECA codes in North America as appropriate n Incentives u Appendix A has not been maintained to the current understanding since its adoption. u It was good for the circumstances and technical understanding at the time of its adoption. u The safety margin of Appendix A is questionable for modern TMCP materials with high Y/T ratio. u Need to extend to strain-based design

6 6Implementation by Yong-Yi Wang DOT/PRCI Project on Weld Code Revision n Involvement of the industry u PRCI u TransCanada u Lincoln Electric u Duke energy n Collaboration with code committees u API 1104 u CSA u ASME n Status u Two public meetings u Results of the first focus area was turned over to API 1104 committee. u API 1104 committee is in the process of drafting the code language. u Work in the second focus area ongoing F Modeling, micro-mechanics, damage mechanics F Correlating small- and large-scale experimental tests

7 7Implementation by Yong-Yi Wang Challenges in Codes and Standards n Outdated n Codes and standards from overseas are becoming de facto standards, particularly in u Offshore u Countries other than U.S. n Code committees may not aware of the status. n Lack of company support n Gap in talent and knowledge n Poor code maintenance, lack of continued update

8 8Implementation by Yong-Yi Wang Actions n Review gaps in codes and standards n Communicate the gaps to the relevant standard committees n Improve and maintain communication with codes and standards committees n Encourage collaborative research among industry, applied research organizations, universities and national labs n Require commercialization plans in proposals n Follow up with commercialization plans u Monitoring u As a criterion for future funding n Government funding agencies need to take a leading role to jump start the standards making and revision process as the industry participation is likely to remain low in the foreseeable future. n Support standards development specifically relevant to the maintenance of existing pipelines
