In-service inspection of pressure equipment in Europe & in Germany

1. In-service inspection of pressure equipment in Europe& in Germany Winfried Schock Head of Competence Centre Pressure Equipment, TÜV Industrie Service, TÜV SÜD Group, Munichemail: winfried.schock@tuev-sued.de This presentation has been developed in the main byDipl. Ing. Czapek and Dr. Rindfleisch, TÜV Chemie Service GmbH, TÜV SÜD Group, Leverkusen

2. 1. Introduction 2. Classification of equipment to be inspected 3. Inspection intervals 4. Performance of inspections 5. Political consequences / The future Agenda

3. Considerable advantages for manufacturers and operators concerningmanufacturing Introduction PED / EN 13... Uniform requirements (ESR) for new pressure equip-ment intended to be placed on market on a legal basis

4. Specification of appropriate inspections in suitable intervals (In-Service) Introduction PED: Hazard Analysis & Instructions for operation are of special importance for safe and economical operation of pressure equipment

5. WGP- Survey on National Regulations regarding In-Service Inspection Participants of the survey: • Germany • UK • Finland • France • Denmark • Portugal • Austria • Italy • Spain • The Netherlands Introduction

6. Many EU-countries Adaptation of the national regulationsfor In-Service Requirements: Classificationof equipment to be inspected according to criteria of conformity evaluation Classification of equipment to be inspected New Equipment/PED Requirements for design, material, manufacturing and inspection results from hazard potential

7. Classification of equipment to be inspected Non uniform national procedures for In-Service: • Usage of criteria of conformity evaluationonly in a simplified wayornot at all • Special rules, exceptionsandrequirements • Differences in frequency and intensity of testing • Different view of owners responsibility / Third Party inspection requirements

9. Inhomogeneous starting position from a competitive point of view within the EU Classification of equipment to be inspected economic efficiency Inspection / downtime costs

10. flexibleintervals T R E N D Inspection intervals Knowledge based Inspection • Increasing relevance of Hazard /Risk analyses and additional NDT procedures for the assessment and specification of inspection intervals • Extensionandreductionof inspection interval is possible

11. Performance of inspections • Authorized inspection bodies(in general with EN 45004 accreditation ) pressure equipment with high hazard potential • User- Inspectorate optional in most of the countries for pressure equipment with high hazard potential • Specialist personnel of the operator / ownerin some countries pressure equipment with low hazard potential • Competent personnel chosen by the operator(e.g. in Germany) pressure equipment with low hazard potential

12. Performance of inspections “User’s / operators experience” vs „Third-Party-concept“

13. Uniform andesssentialsafety requirements • design • fabrication • nature and scope of certificating inspections Improvement of the economic position of European manufacturers Political consequences / The future Manufacture of pressure equipment PED

14. HarmonizationimprovesEuropean User’s Competition Political consequences / The future Operation (In-Service) of pressure equipment About 25 National Regulations and Rules Nouniform requirements for operation !

15. Harmonizationof requirements for operation as well as inspection intervals, intensity of inspection and inspection responsibility Focus on theowner / userresponsibilities Use of Knowledge based specifications for inspection requirements ( “KBI“) Political consequences / The future
