4 Integrity management The HSSE tablestake LoPC Process safety Equipment Integrity - 20 essentielle elementer CUI - Et eksempel Risk Based Approach - RAM Risk assesment matrix - Et Prioriteringsværktøj

5 The Tablestake The balanced scorecard: Customers pletfri performance HSE Performance Stakeholders People

6 Aspekter omkring HSE arbejdet Personlige sikkerhed Process sikkerheden Anekdote: Management has to secure the workplace so the colleagues do not get hurt and can go home at the end of the day to their families in the same conditions as they started. At the same time management has to secure that the workplace remains so the colleagues have a workplace where the can start tomorrow

7 Integrity management The main issue : LoPC Loss of Primory Containment

8 Høj-risiko scenarier Process Safety Eksempel fra Kulbrinte industrien Eksempler af Høj-risiko scenarier» H 2 S udslip i procesområdet.» Gassky eksplosion i procesområdet» Gassky eksplosion ved lastning af tankvogn» Gassky eksplosion i LPG kugletank» Gassky eksplosion ved lastning af LPG skib» Stikflammebrand i procesområdet» Overfladebrand i procesområdet» Brand i flydetagstank» Eksplosion i fasttagstank.» Råolie udslip ved lastning af råolie» Massiv jordforurening

9 The 5 HSSE critical activities for process safety 1. Management of change 2. Equipment integrity 3. Instrument protective functions - cut out systemet 4. Alarm management - operating windows 5. Reliability centered maintenance.

10 Integrity management The HSSE tablestake LoPC Process safety Equipment Integrity - 20 essentielle elementer CUI - Et eksempel Risk Based Approach - RAM Risk assesment matrix - Et Prioriteringsværktøj

11 Selection of essentials in equipment integrity Midlertidige reparationer Management of change Risk based inspection Injectionspoints Inspection of dead legs Small bore piping Pipeline integrity inspections Flare inspection Brittle fracture prevention Dew point corrosion Equipment integrity 20 essential elements Kritiske none return valves CUI korrosion under isolering Soil to air interface of buried piping Flange bolting procedures Handling of pressure relief devices Inspection tank roof/ bottoms Idle and retired equipment Inspection staffing / competances On-stream inspection OSI None intrusive inspection NII

13 Inspection strategy General pipe inspection code er API 570 Code for definition af CUI susceptible areas er API 574 Degradation modes / korrosion Men for CUI 1) age related 2) non age related 3) a strategy based inspection
