FIRE AND GAS LIFE EXPANSION AND MODIFICATION AUSTRALIA BROWNFIELDS CONFERENCE | PERTH | AUGUST 2014 | GEIR SOLEM 1 AUTRONICA FIRE AND SECURITY • A leading innovator, manufacturer and supplier of fire safety equipment • Founded in 1957 • Employs more than 450 persons • ProtecTng life, environment and property • First IEC 61508/61511 SIL 2 approved F&G detecTon system in the world 2 DRIVING PERFORMANCE VS SAFETY Utilization • As business strives for opTmum economic value through throughput and performance, the plant is pushed to its highest safer operaTng limits • Probability of failure increases • Dependence upon Fire ProtecTon systems, people, process and procedures Ope increases ra6n g • Goal: Highest Safety • Strategy: Loop integrity • Method: Fault tolerance & Redundancy • Measurement: Reliability & Availability Availability 3 ECONOMIC LIFE CYCLE OF A PROCESS Plan and purchase Install and commission Operate and maintain Cash Flow Increased plant performance AutroSafe SelfVerify® Time Classic conventional Shorter scheduled outage Faster Plant Start-up Fewer unscheduled outages Increased up-time between scheduled outages 4 F&G UPGRADE – WHY CHANGE? • IEC 61508 SIL2 (no legacy system opTmized for FuncTonal Safety) • More flexible soluTons • Increased quality and safety requirements • Beder integraTon to top systems (SAS/Safety PLC) • Step-‐wise upgrade opTons (keep exisTng detectors) • SelfVerify (automaTc, calibrated tesTng) – reduced tesTng and maintenance 5 AUTROSAFE IFG AUTROSAFE INTEGRATED FIRE AND GAS (IFG) TUV IEC 61508 SIL2 APPROVED SYSTEM 6 AUTROSAFE SELFVERIFY® 7 7 LIVE UPGRADES – CHALLENGES • ConTnuous operaTon • Old and new system – parallel operaTon • Fall-‐back opTons has to be possible • Keep downTme to a minimum – at loop level • F&G panel / top system (SAS) communicaTon 8 PROJECT IMPLEMENTATION Loops AutroSafe F&G alarm system w/loop interfaces for connecTon of old detector loops Config Temporary config without detectors Test TesTng of communicaTon between all panels and SAS Upload Pre-‐made config uploaded Commissioning F&G alarm system ready for changeover 9 PROJECT IMPLEMENTATION Step by step… • All BS-‐100 detector texts exported, processed and uploaded to AutroSafe config. 10 PROJECT IMPLEMENTATION – COMMISSIONING TOOL 11 FROM BS-‐100 TO AUTROSAFE 12 PROJECT IMPLEMENTATION 13 CONOCO PHILLIPS B11: F&G REPLACEMENT Scope of Work Design of new F&G system New documentaTon Replacement of 322 detectors incl. Flame detectors Supervision of offshore work and responsibity for actual installaTon work As-‐built documentaTon 14 CONOCO PHILLIPS B11: F&G CABINETS BEFORE (Servoteknikk) AFTER (AutroSafe) 15 CONOCO PHILLIPS B11: LOOP DRAWINGS Flame detectors Smoke/Heat/MAC 16 BORGLAND DOLPHIN: BS-‐100 TO AUTROSAFE • BS-‐100 to AutroSafe upgrade project. • Scope of Work similar to B11; System design, F&G Cabinet engineering, documentaTon incl. Loop drawings. • Autronica was not responsible for the installaTon. • Use of BS-‐100 adapter socket/plate. • Flame and Gas integrated to AutroSafe via 4-‐20mA interface cards. • Detector count (for replacement) : 109 ea. Gas (HC and H2S) 6 ea. Flame 422 ea. Smoke/Heat/MCP 17 BORGLAND DOLPHIN: CONTROL ROOM 18 BORGLAND DOLPHIN: PROJECT IMPLEMENTATION • Old cabinet moved, but sTll funcTonal. New AutroSafe cabinet installed and commissioned towards SAS. • CommunicaTon between AutroSafe and SAS verified and tested. • Loops gradually transferred to AutroSafe, by creaTng loop breaks and changing to new AutroSafe detectors – 5 at a Tme. • Every day was completed by commissioning and tesTng new detectors and verifying placement in SAS. • PlaHorm always protected. 19 BORGLAND DOLPHIN: F&G CABINETS BEFORE (BS-‐100) AFTER (AutroSafe) 20 F&G UPGRADES: COMMON CUSTOMER CHALLENGES • ConnecTon boxes (JB’s) for detectors (open hidden above ceiling). • Faults or missing informaTon in current (old) documentaTon. Might require changes in the field. • EX equipment connected to non-‐cerTfied equipment. • Consumables like cable glands, blind plugs, cables, JB’s etc are not taken into consideraTon while planning. • Resources, more resources à faster execuTon 21 F&G UPGRADES TO AUTROSAFE – CUSTOMER FEEDBACK • A fully IEC 61508 SIL2 cerTfied system • Flexible changeover -‐ funcTonality maintained • Controlled, scheduled replacement • Minimal downTme and minimal expenses for correcTve measures • Minimal disrupTon to daily operaTons • Significantly reduced requirements for manual tesTng/maintenance • Beder integraTon to SAS top system • Easier updates 22 23
