Asset Life Information Management (ALIM)

Discover the Ultimate Asset Roadmap and Information Management

Aladon’s Asset Life Information Management (ALIM) process is purpose-driven to preserve asset life and the information management necessary for your organization’s successful, ongoing operations.

Our ALIM process results in a comprehensive understanding of the information requirements such as the condition of the assets and related risk issues—and specifically, what is required to continue the safe and effective operation of the assets. It acts like a roadmap for life preservation and asset life extension projects that also enhances ongoing operational excellence.

Based on a holistic plant-wide life preservation and extension model, ALIM provides a structure to evaluate and address design integrity, aging, deterioration, obsolescence, and other asset life concerns to better manage future operations and maintenance practices.

Aladon ALIM Process

Our ALIM process is both qualitative and quantitative where the initial assessment is a high-level understanding of the assets in the field. Operations normally continue using equipment, over months, and sometimes years, beyond the conceived field life. The assessment through analysis and simulation determines remaining life based on design integrity, operating conditions, events, maintenance interventions, corrosion, wear or fatigue, or simple use and time.

ALIM integrates various key elements of business and operations management systems to best assess and manage the asset life to create predictive modeling and improve investment planning.

Although facilities may operate within design parameters, current condition assessment is still required to identify the remaining life of the assets and how to effectively manage them going forward. Aging and operating windows are key elements in the assessment, as is typical wear and tear, deterioration patterns, performance and obsolescence (equipment that is no longer viable, critical to operations, or even in use). This need-based evaluation provides the foundation for the next period of the facility service.

Determining and calculating the remaining life of the assets is a foundational element of the overall Asset Life Information Management (ALIM) process. The objective of the process is to determine the remaining useful life using the specific factors found to influence asset behavior.

In cases where the remaining life may be impacted by factors outside the initial assessment, it is important to create a real life, holistic model of the equipment, systems, subsystems or facility and then simulate the asset “condition” and calculate remaining life for these assets based on the simulation output.

From this type of information, data-driven decisions to preserve or extend the useful life of assets is possible. The decsisions should be in line with criticality and organizational goals.

ALIM Prerequisites

The following prerequisites are considered for an ALIM study:

  • Original design integrity review (what the asset CAN DO).
  • Expansion plan: Future expansion that may impact asset loading and utilization.
  • Changes in the feed composition: Latest composition and lab sample analysis data is considered and any future changes will be considered.
  • Plant Production Profile: Production profile and changes in flow rate and throughput will be studied.
  • As per the business plan, the ongoing project impact is considered in the study. New equipment will be assessed.
  • Any known major program, initiatives that can impact asset life will be assessed.
  • Changes in regulations, legal requirements or codes & standards, which have impact on the equipment/asset life, will be considered in the ALIM study.
  • Although equipment or systems identified as obsolete by the manufacturer would not need further study on remnant life, their life extension options will be evaluated.
  • Return on Investment baseline with reference to % cost is defined so as to compare repair/rehabilitate versus replace options.
  • Determine the Life Extension (LE) period for consideration.
  • Consult with OEM/Vendor to determine life expectancies, obsolescence and rehabilitate options.
  • Shutdown plans and major interventions are considered.

The Aladon Approach

Our world-class methodology to full life-cycle asset management targets assets on a site or in a facility that impact performance and operational efficiency, safety and reliability. This step-by-step approach is based on the principle of safe and effective use of equipment throughout its life while meeting satisfactory performance standards (safety, integrity, throughput, etc.).

The Operating Context determines the deterioration rate and probable failures that can be expected from the assets. Factors in the Operating Context include:

  • Operating Environment and Environmental Regulations
  • Safety Standards and Regulations
  • Batch Process or Flow Process
  • Duty cycles (including redundancy and capacity)
  • Demand (increasing or decreasing)
  • Product and product quality standards
  • Current maintenance and inspection strategy
  • Redundancy

Understanding the factors that influence the asset behavior and the current condition of assets can help organizations determine remaining (remnant) life and what needs to be done to preserve or extend useful life.

The study will provide asset life expectancy based on current condition, maintenance, inspection and operating practices and maintenance data. In order to preserve or extend the useful life (LE), additional remediating actions or failure management strategies (operational and maintenance) may be recommended.

The study recommendations would follow the “Life Extension Option” categories as listed below:

  • RETIRE:
    • Scrap and decommission equipment/system with/without replacement
  • RE-RATE:
    • Revise the role and life with the reduced performance for the remainder of the lifecycle; i.e. by placing greater dependence on other systems
    • Change operating practices, derate the duty, or make favorable modifications to process conditions or chemistry
  • REPAIR:
    • Analyze the margin between the equipment condition and minimum code specification
    • Remove damage with/without repair; if necessary revise the role & performance standard
    • Repair the component temporarily with/without removing the damage
  • REPLACE:
    • Replacement with identical (like for like) or compatible (different type)
    • Replacement with an asset of similar capacity
    • Replacement with a larger capacity asset as part of strategic requirements
    • Replacement with a smaller capacity asset because customer demands have reduced and are unlikely to be increased
  • RUN:
    • Equipment technical integrity and performance are acceptable
    • Revise the equipment performance standards and keep it running with close monitoring to ensure that the revised performance standards are achieved in the long term and to identify any terminal decline before it becomes critical
    • Monitor the equipment to ensure that the extent and rate of the damage does not change sufficiently to compromise Safety & Integrity limits
  • REHABILITATE
