  2. Outline • EO Depot Construction Activities • EO Depot HMAS Stirling Case Study • EO Depot Myambat Case Study • Lessons Learned

  3. EO Depot Construction Activities • AIR 7000 (P-8 Poseidon) / AIR 9000 (MRH90) • construction completed Jun 17 at Twofold Bay (1 ECB and 1 Hardstand) – in use • construction completed Sep 17 at Stirling (3 ECBs) – handover in progress • Taxiway Construction at Edinburgh • Enhanced Land Force (ELF) Project • construction completed Sep 17 at Mangalore (2 ECBs + roadworks + services) • construction commenced Sep 17 at Edinburgh (1 ECB)

  4. EO Depot Construction Activities • EO Logistics Reform Program • Commencing 2018 • Myambat • Amberley • Darwin • Townsville • Mangalore • Williamtown • Twofold Bay • Fort Direction • Commencing 2019 • Cerberus • Edinburgh • Stirling • Pt Wilson

  5. EO Depot Construction Activities • EO Logistics Reform Program • 19 ECBs • 5 APFs • 9 Admin • 9 Light Frangibles (SAA + Flare + WP) • 1 RDF • 5 NE Store • Plus 3 traverses and 5 other facilities • 100% Design completed September 2017 • Construction commencing January 2018 for April 2020 completion

  6. EO Depot Construction Activities • Other Significant Construction Projects • Orchard Hills Asbestos Remediation (2018) • Stirling Wharf Redevelopment (2018-19) • Pt Wilson Wharf Redevelopment (2018/19-21/22) • Roadworks at multiple sites

  7. EO Depot Construction Activities • Background • Explosives Storehouses are sited to meet Inter Magazine Distance requirements • Defence Legal advised previous DEOP101 Risk Waiver policies did not meet Defence’s WHS obligations • Must now demonstrate that risk to construction andEO workers is reduced SFARP • DEOP101 now requires that construction workers must be protected by Inhabited Building Distances (IBD) • risk is commensurate with that in occupied office buildings on Defence sites • If EO holdings and Quantity-Distances cannot be reduced to provide the necessary protection, then alternative risk treatment strategies are required to reduce risk SFARP.

  8. Case Study #1 - EO Depot Stirling • At Stirling, QD rules reduced almost all HD1.1 NEQ limits to 0 kg with ECB construction sites • Alternative storage unavailable for the majority of Stirling’s EO • Depot supports: • Submarines and Major Surface Combatants, • SASR, • RAAF Pearce • Northwest exercise areas • Reserve units • EO Depot Edinburgh (Tier 2 site)

  9. Case Study #1 - EO Depot Stirling

  10. Case Study #1 - EO Depot Stirling • Construction contract in place prior to developing a depot operating plan under these restrictions • Areas of concern: • Impact of reduced EO licence limits on depot operations • Coordination and safety of ship ammunitioning activities • MHF due diligence requirements (eg, high risk work permits, evacuation plans) • Security and access requirements • Licensing risk assessment imposed reduced NEQ limits • Limited consultation on depot operating requirements prior to initial release of licences

  11. Case Study #1 - EO Depot Stirling • Risk traditionally reduced by reducing the Consequences of major EO incidents in EO facilities using Quantity-Distance rules • Assumes than an EO incident may occur, and that facilities and personnel will be at a distance that will provide an appropriate level of protection from harm • During construction, depot ELLs based on Risk Assessment, where risk is reduced by reducing Probability of incidents • What activities MUST the depot do during construction phase? • How can we reduce the probability of major incidents SFARP? • Consequences are significantly greater than accepted under standard QD rules

  12. Case Study #1 - EO Depot Stirling • Buildings immediately adjacent to construction site are empty. • NEQs determined by need, Consequences at construction site would be Catastrophic in a HD1.1 event at nearby ECBs • HD1.1 and 1.2 EO cannot be handled during construction hours in buildings inside Inhabited Building Distance due to high NEQ • Depot started work at 4am, sometimes earlier! • All life-expired stock removed from depot or extended by engineering analysis • Restrictions on shipping activities eg, requirement to abide by 60 day lead time for shipping activities, limited flexibility for late changes

  13. Risk Treatment Strategies • EO handling restrictions in specified buildings during construction hours • Amended working hours (fatigue must be considered) • Access and traffic controls • Removal or disposal of ‘higher risk’ EO (life-expired, safety restrictions) • Nearest box quantity issues and sealed returns to reduce workshop EO movements • Small Quantity Facility licensing of EO workshops • Assign specific roles to buildings (eg, removing 1.1 licences from certain buildings if NEQ levels impractical) • Daily NEQ printouts where NEQ margins are small • Use of direct deliveries from Myambat to support major exercises/activities • Temporary holding areas for EO

  14. Lessons Learned • Early consultation with ADF customers and construction contractors essential • Uncertainty in construction site boundaries during planning • Limited understanding by each party of risks posed by each other • Differences in terminology and lingo • Must understand depot operating requirements • ‘Whole of depot’ perspective required vs ‘licensing by building’ • Security requirements are open to different interpretations • Must be able to demonstrate reduced risk • Numerous other non-EO WHS risks to manage

  15. Case Study #2 - EO Depot Myambat • Construction proposed in three separate phases • Phase 1: • Site Establishment • Guardhouse • Light Frangibles (SAA, Flares, Mechanical Handling Equipment (MHE) Storage) • Phase 2: • 2 large Light Frangibles • Phase 3: • 9 Earth Covered Buildings

  16. Case Study #2 - EO Depot Myambat • Major operating requirements: • Central hub of EO storage network and wholesale distribution • Receipt of EO deliveries from manufacture via commercial ship and domestic manufacturers • Long term bulk storage • Support to Singleton and Williamtown depots • Retail deliveries to Singleton • Direct deliveries of large EO consignments for major exercises • No other depot has the facilities or capacity to meet these needs

  17. Case Study #2 - EO Depot Myambat • Depot Operating Plan developed by Thales in consultation with: • Depot staff and management • Tier 2 sites (Singleton and Williamtown) • Local ADF customers • Defence EO Logistics Reform • Defence EO Licensing Authority • Directorate of Ordnance Safety • Thales EO Services Operations and Security • Thales Explosives Safety Committee

  18. Case Study #2 - EO Depot Myambat PHASE 1 Site Establishment 3 LFBs Guardhouse

  19. Case Study #2 - EO Depot Myambat • Proposed Operating Plan • Phase 1: • Licence ARW workshop as an SQF due to traffic flow and SAA LFB • Operate APB workshop on afternoon/night shift • Relocate EO in westernmost ECBs OR restrict handling in those buildings during construction hours • Relocate EO in specified Light Frangibles until construction complete • Nearest box quantity issues and sealed returns wherever possible

  20. Case Study #2 - EO Depot Myambat PHASE 2 2 x LFBs

  21. Case Study #2 - EO Depot Myambat • Proposed Operating Plan • Phase 2: • Relocate EO in buildings subject to NEQ reductions • License ARW workshop as an SQF due to traffic flow • Nearest box quantity issues and sealed returns wherever possible • Commission new LFBs prior to demolition of old LFBs and start of Phase 3

  22. Case Study #2 - EO Depot Myambat PHASE 3 9 x ECBs

  23. Case Study #2 - EO Depot Myambat • Proposed Operating Plan • Phase 3: • Significant internal EO relocations required • HD 1.2 only in closest row of ECBs • EO handling restrictions in ECBs for long term bulk storage to maintain NEQ capacity while reducing risk • Construction site boundary to be located as far as possible from ECB precinct • License ARW workshop as an SQF due to traffic flow

  24. Case Study #2 - EO Depot Myambat • Major operating challenges • Reduced capacity for returns of EO from other depots • Changes to working hours and shift arrangements • Large numbers of contractors operating on site • Security and access control • Large traffic volumes, damage to roads • Duration of construction project >2 years • Ongoing deliveries of EO procurements throughout the construction program

  25. Summary • Support Defence to complete EOLRP on time and on budget • Keep construction teams safe • Continue to meet ADF requirements for EO while maintaining safe depot operations • Work together to strike the right balance of objectives
