Smarter decisions with clean, structured asset data.
Reliability engineering for maintenance
With John Crane Performance Plus™ our consultative approach covers every asset on your plant, not just rotating equipment.
Our services
Building and optimising asset hierarchy
Improve decision-making based on improved data accuracy and accessibility. By integrating validated hierarchy trees and standardised equipment data into the CMMS, we improve data accuracy and accessibility — providing a solid basis for smarter maintenance decisions and sustainable reliability planning.
CMMS (Computerised Maintenance Management System) master data optimisation
We ensure that each asset is uniquely identified, classified and linked to its location, installation date, criticality, operating conditions and required spares. Complete and accurate data enables effective maintenance, improves operational decision-making and supports long-term reliability.
Asset criticality assessment
Providing the basis for prioritising maintenance and other activities to achieve better decision-making, including the targeting of resources. Each asset is ranked by criticality (A-B-C) based on its impact on business objectives, including safety, environment, production and cost.
Preventative maintenance programmes
A structured approach to developing equipment maintenance strategies, detailed task plans and long-term alignment.
Maintenance activities are based on critical failure modes - typically using RCM or FMECA methods - to maximise uptime, reduce unnecessary tasks and minimise costs across asset classes or individual equipment.
Maintenance plan creation with detailed work instructions
The maintenance plan outlines the required activities for an individual asset. It specifies job frequency/interval, task duration, resource needs, machine status and step-by-step instructions.
This asset-level detail ensures efficient and consistent execution, supporting long-term reliability and performance. When combined across all assets, these individual plans form the overall maintenance programme.
Maintenance programme alignment to long-term plan
A well-aligned preventive maintenance programme ensures all asset plans are practical and executable.
At John Crane, we balance resource availability with operational constraints, such as seasonal conditions or shutdown windows, to prevent delays and reduce the risk of equipment failure due to missed or late maintenance.
Plant reliability data analysis creating actionable insights
Our data-driven approach provides deep insight into maintenance effectiveness and asset reliability performance. This enables corrective actions to improve safety, environmental performance, production and cost efficiency.
We achieve this through advanced analysis of a range of data sources, including maintenance work orders, failure data, plant availability, production performance and equipment reliability, using tools such as Weibull analysis and repairable systems modelling.
Failure investigation and root cause analysis (RCA)
Understanding why a failure occurred can enable faster resolution and long-term corrective actions - improving safety, environmental performance, production and cost efficiency. It also helps ensure that the failure doesn’t happen again.
Our troubleshooting builds on routine monitoring techniques, enhanced with advanced tools like Motion Amplification® to diagnose complex reliability issues in the field. For recurring or critical failures, a structured RCA process uncovers the physical, human and organisational root causes.
MRO inventory optimisation
We ensure the right spare parts are available when you need them to minimise both downtime and inventory costs. This process includes the following inventory practices to improve reliability, reduce delays and ensure operational efficiency:
- Inventory catalogue optimisation through standardisation and deduplication
- Master data cleansing
- Bills of Material (BOM) creation and optimisation
- Spare parts usage analysis
- Recommended stock levels
- Assessment of policy, processes, procedures and practices.

What is CMMS and how can John Crane help you optimise master data?
A CMMS (Computerised Maintenance Management System) is a digital tool used to manage asset data, maintenance schedules, and work orders. John Crane helps optimise CMMS master data by ensuring each asset is uniquely identified, classified, and linked to its criticality, location, and required spares. This improves data accuracy, supports smarter maintenance decisions, and enables long-term reliability planning.
What is RCM and how does it support preventive maintenance?
RCM or Reliability-Centred Maintenance is a structured method for developing maintenance strategies based on critical failure modes. At John Crane, we use RCM to create targeted preventive maintenance programmes that maximise uptime, reduce unnecessary tasks, and minimise costs across asset classes or individual equipment.
What is FMECA and how is it used in maintenance planning?
FMECA (Failure Modes, Effects, and Criticality Analysis) is a technique used to identify potential equipment failures, assess their impact, and prioritise actions. John Crane applies FMECA to develop detailed maintenance plans that address high-risk failure modes, improving reliability and reducing operational risk.
What is the goal of root cause analysis and how does John Crane approach it?
The goal of Root Cause Analysis (RCA) is to uncover the underlying reasons for equipment failures, whether physical, human, or organisational. John Crane combines advanced tools like Motion Amplification® with structured RCA processes to diagnose complex issues, enabling faster fixes and long-term corrective actions that improve safety, performance, and cost efficiency.
How can uptime be improved with John Crane’s reliability engineering services?
Uptime can be improved through proactive reliability engineering, data-driven maintenance planning, and optimised asset management. John Crane’s services, such as asset hierarchy optimisation, CMMS data cleansing, and preventive maintenance programmes, help reduce unplanned downtime, extend equipment life, and maintain operational continuity across your plant.
