Optimizing OT Asset Lifecycle: Maintenance & Upgrades

What measures can assist business managers to properly preserve and exploit Operational Technology (OT) when they can observe the great universe opened by new technologies? Are all passages to OT asset management locked and can the effective maintenance strategies and timely updates be referred to as the keys to the lock?

Precisely, because of those dynamics, there is a need to engage in activities that relate to the active management of assets and the part played by technology in the contemporary business context.

Thus, it becomes possible to determine adequate perspectives for assessing efficient maintenance, main practices, as well as appropriate upgrades underlying the opportunities for managing various challenges of the contemporary industrial setting and attaining better performance.

OT Asset and Its Lifestyle

Operational Technology is defined as hardware components such as items of plant, equipment, and devices that are utilized in industrial processes to measure and manage industrial processes. 

These assets encompass equipment like machines, sensors, controllers, and networks used to automate and integrate process and information flow, especially in industries such as manufacturing, energy, transport, and health. The lifecycle of OT assets typically comprises several stages:

Planning and Acquisition

It refers to the fundamental activities of acquiring and implementing the assets of OT based on operational needs and technology demands.

Operation and Monitoring

This phase involves using the assets to perform their intended tasks as required in their respective fields. Effective ot asset management dictates that continuous monitoring is essential to identify any variations from normal operating parameters. Hence, it has been highlighted that monitoring needs to be carried out continuously.

Maintenance and Repairs

Preventive and corrective maintenance are essential activities to reduce the possibility of an asset’s failure or breakdown, ensure the extension of the asset’s life cycle, and reduce time spent on the maintenance of an asset during its life cycle.

Upgrades and Modernization

Another key driver is the process of modernization which involves replacing parts, software, or other components of OT assets with improved ones to boost functionality, productivity, and adherence to regulations.

Decommissioning and Disposal

Once the assets reach their useful lives, they are properly disposed of in a safe and environmentally sensitive manner in that they have to adhere to laid down laws and regulations concerning the physical environment.

Maintenance Optimization and Management of OT Assets

Optimizing the lifecycle of OT assets offers several benefits that contribute to overall operational efficiency and business success:

Minimized Downtime

 Maintenance strategies that involve regularly anticipating the need for repair and timely replacement of faulty components are critical in keeping machines running and avoiding interrupted production.

Cost Efficiency

Strategic asset management practices enable curbing operational costs by efficiently allocating resources, namely reducing the cost of maintenance, as well as the overall lengthening of the lifespan of the assets.

Enhanced Safety and Compliance

With proper maintenance and timely upgrades, it will support OT assets’ safety and minimize the risks that are inherent with equipment, operational failure, or non-compliance with industry regulations/standards.

Improved Performance

The improvement of old coins to better ones, or the integration of new technologies gives the assets better efficiency, effectiveness, and ability to effectively respond to new business requirements and customers’ needs.

Policies and Practices in Maintaining OT Assets

Maintenance has been highlighted as a central factor in the management of OT assets concerning their operational lifetimes. Implementing structured maintenance strategies ensures the reliability, efficiency, and longevity of critical industrial equipment:

Predictive Maintenance

Relying on data analysis and IoT sensors, predictive maintenance employs both time-based and miles-based analysis, and machine learning algorithms to come up with predictive solutions before a machine breaks down. This approach helps to avoid the utilization of high fixed-cost assets and maximize their availability, hence reducing the use of spare assets.

Preventive Maintenance

Periodic inspections, greasing, and replacement of components are performed on a timely basis due to existing risks of failure and best performance outcomes. Avoidance activities are those that are designed by the equipment makers and other stakeholders based on regularity and usage patterns.

Condition-Based Maintenance

Conditional-based maintenance relies on the ability to constantly keep an eye on temperature, vibration, and fluids. Meanwhile, the CO process involves the analysis of data on the condition of assets and causing maintenance activities when specific and significant changes are observed.

Reliability-Centered Maintenance (RCM)

RCM involves evaluating functions, failure modes, and their consequences to determine the risk priorities of the assets. This methodology creates the understanding of the relevant maintainability option that helps to achieve the optimum reliability of the assets and drop the risks of operation.

Proactive Inventory Management

Stocking essential spare parts and consumables is also important so that they are not far from the equipment requiring them so that when maintenance is required, there will be fewer delays.

Benefits of Strategic Upgrades in OT Asset Management

Strategic upgrades are essential for enhancing the performance, efficiency, and competitiveness of OT assets. Key benefits of incorporating upgrades into asset management strategies include:

Enhanced Efficiency

Replacing old parts or outcompeting systems ensures that limited resources are utilized in the most efficient manner as well as saving on costs needed in the running of organizations and hence contributes to sustainability.

Increased Flexibility and Scalability

The concept of modular upgrades can be effective when attempting to scale a business or implement new operational changes in a fast-paced market environment. Real-time OT systems enable future add-ons and adaptability to changes in business and technological processes.

Integration of Advanced Technologies

The upgrade allows the incorporation of highly progressive technologies in organizations like artificial intelligence, the internet of things, and cloud computing improves data analysis, real-time control, and forecasted maintenance.

Compliance with Industry Standards

New OT assets are also required to conform to current legislation, guidelines, and standards of a specific industry, thus meeting safety and efficiency standards.

Extended Asset Lifespan

Strategic upgrades extend the service life of assets by addressing obsolescence issues, enhancing their reliability, and ensuring sustained performance aligned with long-term OT plans.

Challenges and Considerations

Challenges and ConsiderationsDescription
Integration ComplexityUpgrading legacy systems and integrating new technologies may pose integration challenges, requiring expertise in OT and IT convergence.
Data Security and PrivacyEnhanced connectivity and data exchange in IoT-enabled systems increases cybersecurity risks. Implementing robust security measures is crucial to protect sensitive information and prevent cyber threats.
Skill and Knowledge GapManaging advanced OT technologies and implementing complex upgrades may necessitate specialized skills and training for personnel involved in asset management and maintenance.
Cost and ROI AnalysisAssessing upfront investment costs and calculating return on investment (ROI) for upgrades are critical considerations. Businesses should evaluate long-term benefits and cost savings associated with improved asset performance.


The organizational, technical, and economical lifecycle of OT assets through articulated maintenance and improvement procedures is committed to driving organizational efficiency, reliability, and performance across different industries. 

Through proactive resource maintenance, investment in smart technologies, and targeted system upgrades, businesses can mitigate risks, reduce costs, and enhance competitiveness in a digital-centric environment where technological advancement is pivotal. Industries evolve over time, requiring organizations to adapt through innovation and improved asset management to maintain competitiveness in the market.
