9 The Buncefield incident Fuel depot in Buncefield near London Sunday morning, December 11th, 2005 Failure of level measurement, no change in level indication High level alarm in override. Overspill of 300m 3 of gasoline. Heavy explosion 40 people injured No fatal casualties Depot and surroundings have been heavily damaged Took several days before the fire was under control Environmental emissions and damage.

11 Lessons learned Recommendation 3: Operators of Buncefield-type sites should protect against loss of containment of petrol and other highly flammable liquids by fitting a high integrity, automatic operating overfill prevention system (or a number of such systems, as appropriate) that is physically and electrically separate and independent from the tank gauging system.
12 Lessons learned Recommendation 5: All elements of an overfill prevention system should be proof tested in accordance with the validated arrangements and procedures sufficiently frequent to ensure the specified safety integrity level is maintained in practice in accordance with the requirements of Part 1 of BS EN
13 Post Buncefield effect Oops, can that happen to us too? Are the risk assessments OK? Are the HAZOP studies done? Did we cover all scenarios? Authorities start to interfere Regulations are improved or re-written (PGS 29) Proof testing becomes mandatory! What about SIL?
14 SIL Legal status Legal framework Seveso Directive [ Seveso II - Directive 96/84/EC] Workers protection regulations (social) Environmental regulations Associated permits or license system, local, regional or even national Regulations require state of the art equipment for safety assurance State of the art is defined in standards. i.e. for functional safety EN/IEC [EN August 2002] (generic standard) EN/IEC [EN August 2004] (process industry standard)

16 PGS29:2008, 84 pages Hoogniveau-alarmering en overvulbeveiliging 87. Tanks moeten zijn uitgevoerd met: a. een hoogniveau-alarmering die ter plaatse en / of in de controlekamer, alarm geeft, voordat het hoogst toelaatbare vloeistofniveau in de tank wordt bereikt, zodat maatregelen genomen kunnen worden om de pompcapaciteit te verminderen of het verpompen te stoppen, en; b. een fysiek onafhankelijke instrumentele overvulbeveiliging die bij het bereiken van het hoogst toelaatbare vloeistofniveau in de tank de toevoer naar de tank doet stoppen.
17 PGS29:2008, 84 pages. De betrouwbaarheid van de instrumentatie en beveiligingen moet in relatie staan tot het veiligheidsrisico. Er dient een methodiek gehanteerd te worden die de samenhang tussen de risico s, vastgesteld middels veiligheidsstudies, en (de betrouwbaarheid van de) maatregelen (instrumentatie en beveiligingen) aantoont en documenteert. Voorbeelden van methodieken: SIL-systematiek waarin, afhankelijk van de gewenste risicoreductie, eisen worden gesteld aan de keuze en onderhoudsfrequentie/type van de benodigde regelingen en beveiligingen; (NEN-EN 61511/61508) safety-layerssystematiek, bijv. LOPA; bedrijfsbeleid waarmee het risico gekoppeld wordt aan de maatregel; b.v. bij een scenario met risicowaardering X moeten minimaal twee onafhankelijke LOD s (Lines Of Defense) worden ingezet om het risico te beheersen.
18 PGS29:2008, 84 pages. Toelichting: Indien bij scheepslossingen de tweede beveiliging technisch niet mogelijk is, kan in overleg met het bevoegd gezag hiervan afgezien worden of een alternatieve oplossing worden overeengekomen met een aanvaardbaar beschermingsniveau. Onder fysiek onafhankelijk wordt verstaan: Los van niveaumeting Apart stuursignaal Onder overvulbeveiliging wordt verstaan: Elk systeem dat de toevoer tot de tank automatisch doet stoppen zonder tussenkomst van een operator.
19 Simple instrument safety rules still apply A good High Level Alarm typically: is based on a different physical phenomenon (avoid systematic failures) is Fail to Safe classified for SIL services is active (needs power to operate) is proven technology has all appropriate certificates (IEC 61508/61511) is provided with internal diagnostics is preferably provided with a separate failure alarm can be checked easily. Proof testing has a long, predictable lifetime can be repaired immediately without process interference

21 Fixed Roof SAFE HHLA Solutions Tuning Fork Measurement of aggregation phase by density, Gas versus Liquid Radar and Guided Wave Radar. Measurement of true level using di-electric impedance jump at phase change
22 Liquid Bulk Storage, Independent High Level Alarms State of the art. Liquiphant is always the first solution. SIL2/3 Compliant - IEC61508/IEC61511 Loop approach! Suitable for all Cone Roof Tanks using existing tank fittings. Very simple and cost effective proof testing by push button only!
23 Liquiphant summary Liquiphant is an active in-situ density measurement rather than a switch! Density change of liquids is huge and the absolute density of liquid phase is irrelevant thus providing a robust physical deviation. Easy test methodology using push button activated test generator Simplicity of the concept offers extremely low failure rates. Availability joined to the highest safety level! Proven as robust. Reliable lifetime is typically long!
