3. Introduction: Goals • Define a suitable methodology for RA&QA • Perform a Risk Analysis of design and operation of the telescope, by a suitable methodology for the RA investigation • Define and diffuse the “Quality Culture” • Obtained a common standardisation by an integrated strategy (QA & RA, Health-Safety-Enviroment). C. Sollima, INFN-Pisa VLVnT09, Athens, 15 October '09

4. Introduction: Starting Points 1) Deep study of the overall Project to identify the WPs’ links 2) RA & QA activities in the framework of the KM3NeT Project: • to increase the knowledge about the submarine technologies and neutrinos detection (lesson learned from ANTARES, NEMO & NESTOR Projects) • to prove the reliability of the RA & QA methodology • to identify the weakest points C. Sollima, INFN-Pisa VLVnT09, Athens, 15 October '09

6. Introduction: Methodology • PLAN: • 1STOrganizational Meeting • Deep Study of the project • Find what we need • Find the right questions • Find the less boring • and functional documents layouts • ACT: • Technical Reports: • Writing operations • Control operations • Sending questionnaires • documents recording • Organizational meeting with partners • Do: • Build up Questionnaires (QA - RA) • Questionnaires testing • Sending Questionnaires Deming Cycle • CHECK: • Analyze Answers • Send back Questionnaires and organizational meeting with partners (if necessary) C. Sollima, INFN-Pisa VLVnT09, Athens, 15 October '09

10. Risk Assessment Activities • General RA objective: answer to the questions • What can go wrong? • How probable is it ? • What are the consequences? • Qualitative Analysis • Quantitative Analysis • Dependability Analysis (Fast Analysis) C. Sollima, INFN-Pisa VLVnT09, Athens, 15 October '09

11. Risk Assessment: Dependability Analysis • Unrepairable OM and DU, Maintenance 1 week per year. Different configurations • Unrepairable OM and DU, Maintenance 1 month per year. Different configurations C. Sollima, INFN-Pisa VLVnT09, Athens, 15 October '09

12. Risk Assessment: Achievements • Qualification of the methodology and models through many calculations performed on the concept designs • Application of the methodology and models also to the construction and operation life of KM3NeT • Needs to obtain the failure rates of the components: • From database • Government or commercial data • Test • Maintenance is an issue that affects the availability of the detector and the MTTF of the components and systems of KM3NeT detector C. Sollima, INFN-Pisa VLVnT09, Athens, 15 October '09

13. Quality Assurance Activities • Development of the Quality Assurance System according to ISO-9000 family • - Quality Assurance Manual: plan and organization of the activities of KM3NeT in all its phases to insure that the level of quality defined is achieved • - Definition of the Quality plans and general procedures for KM3NeT to be developed and update, once the project and its phases reach a well defined or modified status • - Definition of the Quality management system • - Definition of the Quality management document • - Definition of a Database for the qualification, construction and operation of KM3NeT C. Sollima, INFN-Pisa VLVnT09, Athens, 15 October '09

20. Quality Assurance: Database Database • For Traceability of the components and systems of KM3Netqualification, construction and operation life of KM3NeT • For document management • During the Design study a prototype function was developed: Test report record C. Sollima, INFN-Pisa VLVnT09, Athens, 15 October '09

21. Quality Assurance: Achievements • Development of QA according to ISO 9001 • To be considering the starting point to implement the KM3NeT Quality Standard through the experience gained by the qualification and optimization processes • To be diffuse in KM3NeT collaboration through training on ISO 9000 and KM3NeT QA System. • Development of the database prototype • its future implementation is already planned • Needs to define a qualification process of components systems and to design testes C. Sollima, INFN-Pisa VLVnT09, Athens, 15 October '09

22. Conclusions • RA procedures and models have been developed and qualified • for the qualification, optimization, construction and operation of KM3NeT • QA System has been developed • it is needed to be updated and implemented to become the KM3NeT QA Standard • It is needed to diffuse it by specific training • A prototype database was realized C.
