Topics to be covered • Some definitions • Why do RAM? • RAM Management

• RAM inputs to design process • How does RAM relate to System Safety? • RAM analysis techniques

• RAM and the System Lifecycle • Scaling and application of RAM • Application of RAM to all transport modes • RAM management artefacts • RAM Standards & Guides • AEO Guide to RAM • RAMSS Working Group


Some definitions:

• Reliability (R): “the probability that a specified item will perform a specified function, within a defined environment, for a specified length of time”

• Reliability depends on environmental conditions (heat, dust, moisture, contaminants/pollutants, vibration, radiation, stop-starts)

• Availability (A): “the measure of the percentage of time that an item or system is available to perform its designated function”

• Maintainability (M): “the probability that a given active maintenance action, for an item under given conditions of use can be carried out within a stated time interval when the maintenance is performed under stated conditions and using stated procedures and resources”

• Mean Time Between Failure (MTBF): in hours or days • Mean Time Between System Failure (MTBSF): in hours or days • Mean Time To Repair/Restore (MTTR): in seconds, minutes or hours


Why do RAM? “Thousands lefT sTranded as eurosTar breaks down in Tunnel”: Evening Standard, UK Thursday 7 January 2010: Thousands of Eurostar passengers were left stranded in London, Paris and Brussels today after "fluffy" snow caused a train to break down in the Channel Tunnel.


Why do RAM? • The train broke down about six miles from the UK entrance to the

tunnel at Folkestone after the wrong type of "fluffy snow" affected its electrics

• Snow melted as it entered the tunnel, causing condensation • The train had been fitted with new and modified air vents aimed

at preventing snow getting into the complex electronic system

RAMs & its application

• Range of capabilities of a product enabling it to achieve specified functional performance, at the required time, for the required duration,

without damage to itself or its environment (IEC 62500). • When applying RAMs we need to consider:

– What is the service strategy / outcome

– RAMs approach to service outcomes with type approved assets

– RAMS approach to service outcomes applying innovation / new technology


Case Study 1: T1 Headway Improvement Project:

• Service Outcome: • 20 tph Westmead to Granville • All Western services to merge through platform 1

• Scope • The project will add 32 CSEE Track Circuit in West Line • The project will add 9 Main Line LED Signal in West Line

• What does this mean….in terms of • Rail operations • Reliability • Maintenance


Case Study 1: T1 Headway Improvement Project:


How was RAMs applied?

• Process followed: • Set the assumptions eg asset condition • asset population • data analysis for last 5/6 years to establish a

failure trend & average failure rate for the asset • Further analysis for T1 corridor

FINDINGS (TREND): • 13 failures occurred (average) in the

network for every 100 CSEE Track Cct. • 21 failures occurred (average) in the

network for every 100 Main Line LED Signal.

IMPACT BY HEADWAY PROJECT ON NETWORK: • additional 4 CSEE track failure will be

introduced in the network • additional 2 Main Line LED Signal failure

will be introduced in the network


Case Study 1 Principles

A number of principles need to be considered: • Service outcomes and asset population • Quantitative vs. Qualitative • Changes in asset criticality (Westmead Junction) • Safety considerations • Degraded mode & Mean Time to Repair

Engineering the Systems

• Reliability and Maintainability requirements are specified in many of the ASA standards across the disciplines for many sub systems. (this can be used where requirements allocation may not have come top down the V cycle)

• Signalling – Computer Based Interlocking requirements

• Electrical – System Requirements result in a Power Study (Fabel) which combined with performance data and the new timetable requirements sets the requirements allocation from the option studies.

“Transport Planners view”

Melissa Jovic: Manager, Rail Network Planning and Service Strategy,

Freight, Strategy & Planning Peter Barfod: SME


Demand Analysis Methodology • In previous TfNSW organisational set

up, PPD has been tasked with strategy, planning and Business Case developments.

• Now, Infrastructure & Services/Rail Service Delivery Group is developing all stages of Business Cases and standard working time table

• Transport Networks/Strategic Rail Transport is in charge of long term rail strategies beyond 2030

• Plan future services in the future - Based upon modelling that predicts

demographics and future patronage; - Forecast changes to other services (rapid

transit, light rail, bus, etc.)


Demand Analysis Methodology • Input to design of

services • Confirmation of service

design


Planning Function Overview

• Plan services for 5 to 20 years in the future - Based upon modelling that predicts

demographics and future patronage; - Forecast changes to other services

(rapid transit, light rail, bus, etc) - Customer expectations for timeliness

• Likely to involve new rolling stock, infrastructure and/ or systems

• Will focus on provision of a new service


Quality of Service

• Measures - Punctuality - Passenger Delay Minutes - Quantity of Services Cancelled

• Influences to QOS - Timetable complexity - Infrastructure constraints - Operational responses to degraded mode to restore

normal services.


RAM Approach for Rail Planning

• Determine required performance for the infrastructure that supports a service – the rail line E2E;

• Allocate to components: rolling stock, infrastructure, operations, force majeure.

• Specify in Projects • Allocate to sub-components


RAM and the Operational Concept

• OCD should describe the operations for the service (versus specific assets): Normal, Degraded, Emergency, Possession modes etc. to achieve the QOS.

• Achieve a balance: - Service hours of operation vs time/ cost for preventive

maintenance possessions vs (additional) cost of assets requiring fewer possessions;

- Long term maintenance (cost and possessions) vs (additional) cost of assets.

ASA Technical Forum – Sy ristems Enginee75 ng – Application of RAM on TfNSW, 3 Sep 2015 | 75

RAM and the Maintenance Concept

• MCD should describe the how maintenance is performed on the line (E2E) to achieve the QOS. - Preventive maintenance to achieve reliability targets

(possessions) - Reactive Maintenance to restore services due to asset

(response time, maintainability) - Assessments to determine equipment types, required

possessions, response time, maintainability, etc. must include associated OPEX costs.


RAM and the Business Case (CapEx + OpEx + Risk)

Review Assessment Criteria Sustainability - Are the options likely to have a better sustainable lifecycle than other like assets or the asset the proposal is replacing? Cost Management - Are all whole-of-life cost elements identified? Business Need and Benefits Problem - Is it clear what the problem is that the program/project needs to address? Alignment - Is there alignment to services contracts?

Contd..


Contd.

Funding &Value for Money

Can the whole-of-life cost be justified by the anticipated improvement in services including any assets created, made obsolete or disposed from a whole-of-portfolio perspective?

Sustainability

Are the options likely to have a better sustainable lifecycle than other like assets or the asset the proposal is replacing?

Cost Management

Where the project will also have an operating impact, you should also provide estimates of the changes to ongoing operating costs.


RAM and Business Requirements

• Currently BRSs specify QOS KPIs that apply to the operator; • A BRS should specify the design targets for service punctuality, reliability and

availability;


Opportunities

• Establish a RAMS strategy and policy • Determine the required performance for the rail line E2E • Determine the performance capability for the rail line • Benchmark

NWRL RAM - Background NWRL - efficient and reliable rail services to customers to performance levels

comparable to similar railway services operating in other parts of the World.

Opportunities:

– New rapid transit network to Sydney in the North West comparable to other rapid transit systems worldwide

Risks:

– Provisional targets are too high -> increase cost and programme

– Existing ECRL equipment to be re-used will not meet the performance targets

Issues:

– Reference Design will not be sufficiently defined to confirm the performance targets can be met.

NWRL - PERFORMANCE REQUIREMENTS 98% Trains on-time to 2 minutes at terminal stations

99.5 % of planned train services will operate

On time Running - Benchmarking performance target of 98.16% - average of three leading international metros (Thailand, Hong Kong and Singapore) appropriate to the style of operations envisaged for the NWRL.

Availability – NWRL concept design (RailCorp) derived a figure of 98.89% - benchmarked against the (Sydney Metro) figures of 99.5%.

99.5% availability was adopted as the proposed target to meet the business requirements for the NWRL.

RAM ASSURANCE OBJECTIVE Primary objective of RAM Assurance - provide confidence that the NWRL will

be capable of achieving the required Service Reliability, for a predicted overall cost.

On time running and availability analysis conducted on the NWRL Reference Design to validate the assumed figures.

Analysis was based on, functional block diagrams & functional analysis, fault schedules, with predicted failure rates (for service critical items only), failure modes, effects and criticality analysis of rail systems and infrastructure and an availability model for infrastructure and rolling stock.

Transport Service Delivery view

Dave Spiteri: Director, Infrastructure Management,

Infrastructure & Services Division


Service Delivery View • Infrastructure and Services Delivers the Service

Outcome through O&M Contracts • RAMs is paramount to TfNSW delivering the customer

outcomes • RAMs to the customer is a lot simpler, from the

Customers view: • Reliability is the transport mode arrives on time and

gets to the destination on time • Availability is that throughout the full journey all aspects

of the experience are available (transport mode, carpark, information etc)

• Maintainability is that it is invisible, they don’t want to see it


Service Delivery View With all this the realities of resource availability has to be considered: • BRS and SRS must be balanced • It is NOT a shopping list. • The Whole of life cost solution must be considered • The existing Operate and Maintain budget must be

considered • What are we going to increase the O&M Costs by and

where will the Budget come from • For example It can’t be we are comparing 3 new trains to

each other, need to compare to the current fleet • We have $x to maintain a train now

An Operator/Maintainers view

RAM Asset Management An Operator/Maintainers view

RAM is most effectively identified at the procurement stage of an assets life, and a way of modelling the suitability of an asset to achieve the best outcome

The levels at which Reliability, Availability and Maintainability are achieved will fluctuate during the life cycle of the asset

It is important to realize that most Public/Private Partnerships will be for defined contract periods, often shorter than the life of the actual asset

At this point it is worthwhile pointing out that with a PPP venture, the motivations between asset owner and operator/maintainer can be driven by different wants and needs

TfNSW, being the asset owner, has a strong interest in whole-of-life, cradle-to-the-grave, viability of an asset. But with assets that have lifespans of many years, and in some cases decades, PPP commercial participants have a visibility of whole-of-contract, which can be a very different timespan to the asset life. So two issues become fundamentally

important; TIME and DATA

113

114


So two issues become fundamentally important; time and data We have seen, today, how RAM functions in the life-cycle of an asset, but it

is worthwhile exploring how we make it function consistently across multiple contracts and the Operator/Maintainer in the life of an asset

115


TIME

116


DATA

117


As we have seen, the definition of RAM contains these two key elements in each point, to be able to correctly manage the best outcomes

Time is the metric used to determine the outcome of each point Key data is the essential component to determine the success, or otherwise,

of that outcome

118


Reliability (R): “the probability that a specified item will perform a specified function, within a defined environment, for a specified length of time”

Reliability depends on environmental conditions (heat, dust, moisture, contaminants/pollutants, vibration, radiation, stop-starts)

Availability (A): “the measure of the percentage of time that an item or system is available to perform its designated function”

Maintainability (M): “the probability that a given active maintenance action, for an item under given conditions of use can be carried out within a stated time interval when the maintenance is performed under

stated conditions and using stated procedures and resources”

119


Because commercial operators have stewardship over an asset for a period that is often only a portion of its economic or planned life, there can be commercial pressures to work the asset harder in the duration of a contract, thus threatening the planned duration of an asset’s total life, unless asset condition is clearly codified and measured through the duration of the contract.

…and this is where the DATA comes in

120


With a comprehensive dataset for an asset, it enables a commercial operator/maintainer: To clearly assess the asset condition, and resource it during the

bid phase, so all parties to the PPP have a “no-surprises” expectation when entering into the contract

Accurately manage RAM to support the expectation of the current contract, but to also deliver the asset at contract completion, in a condition that is required and expected by the asset owner in order for the asset to continue its planned service for its expected lifecycle

Allow the asset owner to retain a valid and effective dataset for the asset that has been maintained, with integrity and continuity, by the operator/maintainer as part of the agreed condition preservation

121


The data and its continuity need to be seen as a part of the asset stewardship, almost as a physical component of the asset itself

The principals of RAM management are self-evident but how they are interpreted and applied effectively come down to the clear and unambiguous documentation of condition at any given point along the whole-of-life timeline of the asset along with the planned outcomes of the asset

There also needs to be an active dialogue between Asset Owner and Operator/Maintainer to reassess the validity of initial whole-of-life assumptions For example, increases in timetable schedules will relate to more

productive hours per calendar week/month/year in service, and a decrease in the availability of the asset to undergo maintenance, which can change the whole-of-life profile of the asset. These issues can significantly change RAM assumptions and actions.

122


There are a number of phases in an assets life that may, or may not, come under the influence of an Operations/Maintenance in the course of a contract

This where the continuity and quality of data associated with an asset can make or break the expected whole-of-life expectations of the asset owner

123


RAM support during Defects & Liability phase

This is a crucial time for the Operator/Maintainer to record critical data and feed it back to the asset owner

Assist with discovery of potential issues and the suitability of the asset measured against its planned outcomes

Is the asset capable of achieving the RAM expectations identified in procurement?

RAM and Annual Asset Maintenance Plans

This is where the data made available from the asset owner becomes critical to ensuring the asset condition is maintained from end-to-end of the contract and places the asset in the required condition for subsequent contracts

RAM needs to meet the outcomes of the contract cycle and still achieve the whole of life condition across contracts

124


RAM and Maintenance Resources/Effort Accurate asset data is essential for Operator/Maintainers to forecast

its resourcing requirements to ensure that there are no surprises or growth of contract costs due to poor RAM assumptions

RAM and Asset Condition Assessment Surveys It is critical that clearly defined asset condition can be quantified,

measured and forecast so that RAM compliance can be monitored at any given point in an assets life cycle for its suitability and sustainability.

RAM in Asset Data Management Asset data management should be a codified requirement of any

asset management contract to support the full realisation of an assets lifecycle and to provide the essential support for new asset acquisition

125


RAM and Decisions to Renew or Replace or Upgrade The essential data accumulated in the life of an asset will point

to the actual point of viability failure Prepares the asset owner for Renew/Replace/Upgrade

determination prior to service failure Review of actual RAM achievements against original asset

assumptions and maintaining an agreed data standard Removes the old requirements for tacit assumptions from

employees who had been associated with assets over many years, which often is not the case with Operator/Maintainers in modern arrangements.
