Banedanmark – optimising life cycle costs By Søren Boysen, Director of Technical Operations - Banedanmark Deloitte – Managing Megaprojects, December 2015 Agenda • Introduction to rail assets and Banedanmark investment profile • The anatomy of rail superstructure and bridges • Asset Management regimes • The LCC-approach • Renewal plan + case West Funen • Benefits and challenges 2 Assets within rail infrastructure Signalling Bridges & Interlocking Rail Catenary & Buildings Power 300 2,400 6,800 3,200 km 1,500 km radio masts bridges signals rail overhead line 200,000 2,400 980 3.800 535 network units buildings crossings switches cooling plants 7,500 km 540 100,000 2,300 cable systems platforms relays control boards 1,200 info monitors 3 Banedanmark fundings 2013 - 2019 4 Maintenance budget 5 Renewal budget 6 Agenda • Introduction to rail assets and Banedanmark investment profile • The anatomy of rail superstructure and bridges • Asset Management regimes • The LCC-approach • Renewal plan + case West Funen • Benefits and challenges 7 Components – track superstructure Different lifetimes on the components in track structure Rails Sleepers Ballast Gravel Subsoil 8 Bridge components Different lifetimes of bridge components 9 Agenda • Introduction to rail assets and Banedanmark investment profile • The anatomy of rail superstructure and bridges • Asset Management regimes • The LCC-approach • Renewal plan + case West Funen • Benefits and challenges 10 Rail infrastructure Asset Management regimes How to secure high availability and optimal LCC Strategies Method Results Availability • Following risk of failure. • Minor disturbance of traffic. Risk based approach • Maintenance and large renewal • Less volume in projects in same closure • High unit costs • Work in night shifts – or short closures. • Full renewal of all railcomponents • Use LCC-model to predict and • Full line closure. LCC-optimal plan renewal 4 years ahead. • Life prolonging activities. • Ten year renewal pause • Maintenance on end-of-life lines. • Bundle renewal activities across • Renewal of individual railcomponents assets – sleeper, rail or ballast. Or in combination. 11 Agenda • Introduction to rail assets and Banedanmark investment profile • The anatomy of rail superstructure and bridges • Asset Management regimes • The LCC-approach • Renewal plan + case West Funen • Benefits and challenges 12 The development of LCC-models TAM: Track Analysis Model BAM: Bridge Analysis Model 2015: CAM: Catenary Analysis Model 2014 TAM 2 2012 BAM 1 CAM 0.1 CAM 0.1 2011 BAM 1 TAM 2 2005-2006 TAM 1.1 2002-2003 TAM 1.0 Ongoing development and updating of Asset Management System 13 Model structure Technical engineering relationships: Financial optimization for each line section without constraints • Deterioration of the assets described by Service (only a 10 year renewal pause) Life relationship. • Maintenance activities described according to European models for tracks. Sub models Technical Unconstrained Constrained Inputdata optimality LCC-optimality LCC-optimality • Asset data Financial optimization for each line • Unit cost section with constraints, e.g.: • Traffic hinderance cost • Total renewal budget • Model parameters • Total activity budget 14 The methodology The Bath Tub model Postponed renewal Speed reduction Costs Costs Renewal costs Costs Maintenance costs Lifetime Lifetime Time of Optimal time of Optimal time of Optimal time of Postponed time investment/ investment/ renewal renewal of renewal reinvestment reinvestment In case of postponed renewal: • Increased maintenance costs • Increased renewal costs • Risk of speed reductions (traffic hindrance costs) In case of early renewal: • Penalty 15 Example - track Rails Sleepers Ballast Gravel Subsoil Installation date (inputdata) Technical optimal time to renew KM 0 1 2 3 4 5 KM 0 1 2 3 4 5 Rail 1966 1968 1966 1964 Rail 2026 2028 2026 2024 Sleeper 1987 1987 1987 Sleeper 2027 2027 2027 Ballast 1998 Ballast 2028 Consequence: Renewal each year Technical optimal to renew LCC- optimality -Full renewal 2027 KM 0 1 2 3 4 5 KM 0 1 2 3 4 5 Rail 2026 2028 2026 2024 Rail 2027 2027 2027 2027 Sleeper 2027 2027 2027 Sleeper 2027 2027 2027 Ballast 2028 Ballast 2027 Consequence: Activities are bundled No traffic disturbance between renewal pauses 16 Agenda • Introduction to rail assets and Banedanmark investment profile • The anatomy of rail superstructure and bridges • Asset Management regimes • The LCC-approach • Renewal plan + case West Funen • Benefits and challenges 17 Renewal plan Major track possessions 2015-2018 18 Renewal of rail infrastructure on West Funen Daily train operation: • 114 passenger trains • 10 freight trains West Funen 19 West Funen Track and ground works Replacement of 30 switches Establishing 2 new switches, Middelfart Catenary works Elimination of 13 switches Establishing “protective earthing areas” on 17 Track renewal of 2.4 km track including new ballast bed bridges Upgrading of 4 buffer stops Adjustment of power line on 75.5 km track Establishing one crossing on Odense Station and 30 switches Establishing a dirt road on Odense Station Reconstruction related to the elimination of 13 Establishing 17.3 km new ballast bed switches Establishing new ballast bed under all replaced switches Ballast sanitation of 53.4 km track Replacement of “protective earthing” related to track works Neighbouring projects Replacement of protective covers related to New walking tunnel in Middelfart track works New insulation of two bridges Platform works on Ejby, Tommerup, Gelsted Drainage tasks Signalling Programme (new cables) 10.5 km drainage Tasks related to interlocking systems and switch heaters 5.3 km ditch New platform, Langeskov Station 20 Billede indsættes. 21 Billede indsættes. 22 Billede indsættes. 23 Agenda • Introduction to rail assets and Banedanmark investment profile • The anatomy of rail superstructure and bridges • Asset Management regimes • The LCC-approach • Renewal plan + case West Funen • Benefits and challenges 24 Benefits and challenges Benefits Challenges • Cost savings • Constraints on passenger and freight traffic • Potential for bundling of projects • High demand for coordination between asset • Fewer passenger disturbances/fewer groups announcements • Operator: Some passengers are lost to the • Operator: Possibility for major rolling stock alternative transportation form (car) repair during the possession • Entrepreneur: Risk of resource • Entrepreneur: Effective use of resources overload/capacity constraints (men/machinery) • Entrepreneur: Flexibility within work site area • Neighbours: Only one long disturbance rather than many nights/weekends 25 Langeskov Station Questions? 26.
