Q

The term ‘Whole life-cycle’ has sometimes been referred to as ‘cradle-to-grave’. Explain this analogy. (3)

A

‘Cradle’ refers to the start of the asset life, not from operation but from a response to a clients brief.

‘Grave’ refers to the end of the asset, this may be termination or demolition, but it refers to the point at which an asset no longer holds value to the user.

The asset is ‘disposed’ of, and will then be removed from the operational assets that the company manages.

Q

Identify and discuss three key considerations for an organisation, in relation to ‘Customers’. (4)

A
  • Value of the asset for the stakeholder
  • Demand for use of the asset from the stakeholder
  • Current culture for use (i.e. public transport might be used more due to congestion)
  • Preferred technology use (e.g. pay by phone for parking instead of pay and display)

Q

Why is it important to communicate with stakeholders when considering how to best optimise the service life of an asset? (6)

A
  • Stakeholders (end users) will be able to inform asset owners how they want to use the asset, or how they are already using it.
  • The organisation can make decisions based on proposed/existing use and spare capacity.
  • Asset owners should tell users what they are doing to the network, this can help with a culture change in asset use.
  • A good example is smart meters in homes, which benefits the user as they can manage their energy, equally the organisation can get more reliable information and reduce the amount of home visits they need to make.

Q

Explain and provide examples of ‘Safety’ as an advantage of the risk management technique for use in infrastructure asset organisations.

A

Greater safety and environmental protection due to:
- Improved maintenance of protective devices
- Systematic review of safety implications in failures
- Application of clear strategies for preventing failure modes
- Fewer failures caused by unnecessary maintenance

16
Q

Explain and provide examples of ‘Performance’ as an advantage of the risk management technique for use in infrastructure asset organisations.

A

Improved operating performance due to:
- emphasis on maintenance requirements of critical elements
- extension or elimination of overhaul intervals
- Shorter and more focused maintenance
- Less extensive and costly shut downs
- Fewer ‘burn in’ problems after maintenance
- Identification of unreliable components

17
Q

Explain and provide examples of ‘Cost effectiveness’ as an advantage of the risk management technique for use in infrastructure asset organisations.

A

Greater cost effectiveness due to:
- Less extensive maintenance routines
- Prevention of expensive failures
- Clearer operating policies
- Clearer guidelines for acquiring new maintenance technologies

18
Q

Explain and provide examples of ‘Quality’ as an advantage of the risk management technique for use in infrastructure asset organisations.

A

Improved quality due to:
- Better understanding of equipment capacity and capabilities
- Clarification of equipment set-up and requirements
- Confirmation or redefinition of equipment operating procedures
- Clearer definition of maintenance tasks and objectives

19
Q

Explain and provide examples of ‘Life-cycle cost’ as an advantage of the risk management technique for use in infrastructure asset organisations. (shorter answer)

A

Reduced life cycle costs by optimising maintenance workloads and providing a clearer view of spares and staffing requirements.

20
Q

Explain and provide examples of ‘Equipment Life’ as an advantage of the risk management technique for use in infrastructure asset organisations. (shorter answer)

A

Longer useful life of expensive items due to an increased use of on condition maintenance techniques.

21
Q

What is the lowest point of the total impact line on a cost/risk impact to maintenance and replacement graph represent?

A

The economic optimum- where the total impact on the business is the lowest. e.g. the money is spent efficiently to run the asset.

22
Q

What does the intersection point of the risk exposures and preventative cost lines on a cost/risk impact to maintenance and replacement graph represent?

A

Where the preventative costs and risk exposure are equal, but it is not the optimum operating financial position for the company.

23
Q

What is the purpose of the ‘Cost/risk Impact vs. Inspection/Maintenance/Replacement Interval’ graph for maintenance programmes?

A

The graph shows the risk exposure of the company in terms of £/year based on the predicted maintenance interval.

It also identifies that at the outset of the project, there will be a greater benefit in spending more money on preventative costs to ensure the asset is running efficiently. This may be due to consequences of failure or downtime of operation.

24
Q

What is a risk-based maintenance strategy based on?

A
  • Risk assessment
  • Maintenance planning based on risk
25
Q

What is reliability centred maintenance based on? (4 questions)

A

Key questions:
- What is the system FUNCTION
- What functional FAILURE are likely to OCCUR
- What are the CONSEQUENCES of failure?
- What can be done to REDUCE the failure?

26
Q

What is reliability-centred maintenance?

A

A framework that enables the definition of a complete maintenance regime based on some key questions.

27
Q

Describe remote-condition monitoring.

A

RCM uses sensors and live performance data to make decisions about assets.

It includes automated inspection and data collection, and is mainly used in the rail industry.

28
Q

Draw the risk based maintenance diagram

A

Flow chart including the following:

Collect data ->

Risk Evaluation:
- Evaluate probability of failure ->
- Evaluate the consequence of failure ->

Rank Risks ->

Create inspection plan ->

Propose mitigation measures ->

Reassessment -> (Links back to risk evaluation)

(Refer to cue card 1)

29
Q

Draw the reliability-centred maintenance diagram

A

WBS with ‘Reliability centred maintenance’ at the top.

Four sub-sections on the same level including:
- Reactive
- Preventative
- PT&I based
- Proactive

(Refer to cue card 2)

30
Q

Draw the remote condition monitoring diagram

A

Ensure it depicts remote monitoring and data being transferred to a central point for translation to decisions.

(Refer to cue card 3)
