Frequently asked questions

Asset performance management software brings inspection, integrity, reliability and maintenance information onto one asset model so decisions about equipment are made from a single record of its condition, risk and history. It sits between engineering assessment and maintenance execution, converting condition and risk into prioritized inspection and maintenance plans.

AccurAPM is asset performance management software for oil, gas, petrochemical and power operators. It brings risk-based inspection, inspection data management, Reliability Centered Maintenance, asset criticality and integrity operating windows onto one governed asset hierarchy, so inspection and maintenance decisions draw on the same equipment records rather than separate spreadsheets.

AccurAPM implements API 580 and API 581 for risk-based inspection, API 584 for integrity operating windows, and ASME material data with Tmin calculation. Pipeline integrity follows DNV-RP-F116, ASME B31.8S and API RP 1160. Fitness-For-Service assessments follow API 579-1/ASME FFS-1.

Yes. AccurAPM runs in the cloud or entirely on your own network. On-premises deployment matters for operators whose integrity and process data cannot leave their infrastructure. User accounts can be created through your existing LDAP group or manually, and roles, sites and data permissions are configured per customer.

AccurAPM is used by oil, gas and petrochemical operators and their asset integrity, inspection and reliability engineering teams. Deployments span onshore and offshore facilities, including multi-platform offshore installations, and cover more than 400 deployed assets across risk-based inspection, inspection data management, pipeline integrity and CMMS integration.

A CMMS schedules and records maintenance work. AccurAPM decides what should be inspected or maintained and when, by assessing damage mechanisms, risk, criticality and remaining life, then passes that plan to the CMMS. AccurAPM integrates with CMMS platforms including SAP, IBM Maximo and Oracle, reading equipment, functional location and work history, and writing back notifications and work orders.

An inspection data management system is the system of record for inspection results — thickness readings, findings, anomalies, recommendations and their close-out — structured by equipment and condition monitoring location. Because the history is held in structure rather than in documents, AccurAPM calculates corrosion rates and remaining life from recorded measurements rather than estimating them.

Yes. AccurAPM provides baseline data loading templates for bulk import of inspection history and thickness data, and a data loader in the Core module for migration. AI-based extraction from PDF drawings and technical documents is also available to convert existing engineering documents into structured, linked records.

AccurAPM calculates corrosion rate from successive thickness measurements at each condition monitoring location, then derives remaining life against the calculated minimum thickness. MAWP and Tmin are calculated from ASME material data. Remaining life then feeds inspection planning, so the next inspection date follows from measured degradation rather than a fixed interval.

An integrity operating window is a defined range for a process parameter — pressure, temperature, flow or composition — within which equipment degrades at the rate its inspection plan assumes. AccurAPM establishes and maintains these in line with API 584, detecting and recording excursions rather than leaving them merely observed.

AccurAPM integrates with plant historians and OPC / OPC-UA data sources through its integration layer. Historian tags and operational readings are mapped to the AccurAPM asset hierarchy and equipment context, with data-quality controls for tag mapping, validation, transformation and exception handling applied before readings are consumed.

AccurAPM detects and records the excursion, including start time, duration, severity and the affected equipment or corrosion loop. Dashboards and alerts highlight active or recurring abnormal conditions for engineering review, and the excursion record is available within risk-based inspection, corrosion and inspection workflows to support risk review and inspection planning.

AccurAPM provides a configurable MoC workflow to manage and document changes, with configurable checklists and questionnaires, configurable exceptions, supporting risk assessment, team member assignment and attachments. MoC actions are tracked, and the approval cycle is configurable. The workflow itself is tailored during the design workshop to match your procedure.

Change management sits in the corrective action stage of the AccurAPM strategy cycle, alongside recommendations, so a change arising from an inspection finding or a risk review is raised and tracked in the same system as the finding that prompted it.

Risk-based inspection sets inspection scope and interval from the risk each item of equipment actually carries: the probability of failure given its active damage mechanisms, combined with the consequence if it fails. It replaces fixed-interval inspection, concentrating inspection effort on equipment where failure would matter most.

AccurAPM needs the equipment register and design data, materials of construction, operating conditions and process fluid composition, plus inspection history and thickness measurements. Corrosion control documents and any existing integrity operating windows feed the assessment. Baseline data loading templates allow bulk import so existing records do not have to be re-entered.

Time-based inspection inspects every item on a fixed calendar interval regardless of condition. RBI ranks equipment by probability and consequence of failure, then sets scope and interval from that ranking. AccurAPM supports both, and condition-based inspection driven by remaining life, minimum thickness and MAWP calculations from recorded measurements.

Yes. AccurAPM implements the API 581 quantitative methodology, calculating both safety and financial risk with the risk target set on damage factor, financial, safety or a conservative combination. It supports API 581 damage mechanism screening, corrosion loops integrated with integrity operating windows, and reassessment triggers.

It varies from case to case. The timeline depends on the size of the equipment population, the condition and completeness of existing inspection and design data, and how much of it can be bulk-loaded rather than rebuilt. AccurAPM provides baseline data loading templates so existing records are imported rather than re-entered.

Fitness-For-Service is a calculated engineering assessment that determines whether equipment containing a flaw — metal loss, a crack-like indication, a dent, or creep damage — is safe to keep in service, and on what conditions. It answers whether to run, repair, re-rate or replace, using the measured condition rather than a pass/fail inspection judgement.

Yes. The AccurAPM Fitness-For-Service module supports both Level 1 and Level 2 assessments to API 579-1/ASME FFS-1, so a flaw can be screened at Level 1 and, where that is not conclusive, taken to a Level 2 assessment within the same record rather than moving to a separate tool or spreadsheet.

Asset criticality analysis ranks systems and equipment by how much their failure would matter, scoring consequence across categories such as safety, environmental and financial, combined with probability of failure. The resulting ranking then guides which equipment justifies risk-based inspection, preventive maintenance or condition monitoring.

AccurAPM provides a configurable risk matrix and configurable questionnaires so assessment is faster and consistent between assessors. Criticality assessments carry a configurable approval cycle, team member assignment and attachments, and baseline data loading templates allow existing criticality data to be imported in bulk.

The AccurAPM RCM module determines the maintenance strategy for each asset from its functions, failure modes and the consequences of failure, deciding which failures justify preventive work, which justify condition monitoring, and which are acceptable to run to failure. It structures this around the seven RCM questions with a reusable failure mode library.

Yes. FMECA is part of the AccurAPM RCM module, which covers functions, failure modes and effects with risk assessment applied to each failure mode. Criticality can be defined within the RCM process itself, while the separate Asset Criticality Analysis module provides high-level criticality screening across systems and equipment.

Both draw on the same asset hierarchy, so criticality from RCM and risk from RBI reference identical equipment records rather than parallel hierarchies. In the AccurAPM strategy flow, asset criticality analysis, risk-based inspection, remaining life, interval basis and RCM all sit within one strategy development stage feeding a single execution and corrective action cycle.

Root cause analysis is a structured investigation that establishes why a failure occurred, rather than only what failed. In an integrity context it links the failure back to damage mechanism, operating conditions and inspection history, so the corrective action addresses the cause and the same failure is not repeated elsewhere in the plant.

AccurAPM Root Cause Analysis supports 5 Whys, Fishbone and Fault Tree Analysis, together with sequence-of-events reconstruction and guided structured investigation. Each investigation references the same asset hierarchy as inspection and maintenance records, so a failure is examined against the equipment's own recorded condition and history.

AccurAPM holds inspection findings, anomalies, thickness history and work history on the same asset hierarchy an RCA investigation references, so an investigation draws on recorded condition and maintenance data for the equipment rather than a separate file. Resulting recommendations are tracked to close-out through the same action tracking used elsewhere in AccurAPM.

An AccurAPM RCA investigation produces a traceable record: the identified cause with its supporting evidence, the method used to reach it, and recommendations tracked through to close-out. Because findings sit on the equipment record rather than in a separate document, they remain available to later inspection and reliability work.

AccurAPM Lifecycle Cost helps organizations evaluate total ownership expense and optimize long-term cost. It supports a life cycle cost perspective in which cost is considered alongside asset strategy and performance, so repair, replace and run-on decisions are made against whole-life cost rather than immediate spend.

AccurAPM Pipeline Integrity Management provides a risk-based framework for assessing, prioritizing and managing pipeline integrity across onshore and offshore systems. It evaluates probability and consequence of failure across major pipeline threats and converts the resulting risk profile into prioritized inspection, monitoring, testing and mitigation activities.

AccurAPM pipeline integrity assessment follows DNV-RP-F116, ASME B31.8S and API RP 1160. Integrity assessment criteria are built on probability-of-failure and consequence-of-failure criteria, with threat management, inspection planning, defect tracking, integrity operating window monitoring and action tracking in the same module.

Yes. Pipeline integrity management in AccurAPM covers onshore and offshore systems within the same risk-based framework. Offshore pipeline scope has been delivered as part of a multi-platform offshore deployment, implemented alongside risk-based inspection, inspection data management, SAP integration, process historian integration and 3D visualisation across five platforms.

AccurAPM provides a structured environment for managing cathodic protection engineering data, inspections, risk assessment and performance monitoring. CP survey results are recorded against the asset hierarchy, so protection performance sits alongside the corrosion and inspection history for the same equipment.

AccurAPM Core provides a multi-level asset hierarchy with as many levels and items per level as required, plus security management defining sites, roles and data permissions. Every module references that one hierarchy, so criticality, risk, inspection history and maintenance actions describe the same equipment rather than diverging across systems.

AccurAPM Core allows unlimited users, created through an LDAP user group or manually. Each user is assigned roles and sites, which grant privileges according to data permission. Sites, roles and data permissions are all configurable by the customer rather than fixed by Accur Digital.

Yes. Query Composer lets users connect several entities through pre-defined joins, select fields across tables and extract the result to Excel. Queries can be saved and managed as a custom reporting tool. AccurAPM also ships a baseline dashboard, which is configured to customer requirements during the design phase.

AccurAPM integrates bi-directionally with SAP through AccurELT. It reads equipment, functional location and work history from SAP into AccurAPM, and writes notifications and work orders back to SAP, so an inspection recommendation raised in AccurAPM becomes executable maintenance work without re-keying.

No. AccurAPM complements an existing CMMS rather than replacing it. The CMMS remains the system that schedules and records maintenance execution; AccurAPM determines what work is justified and when, from risk, criticality and remaining life, and passes that plan across the integration.

Accur3D provides intuitive 3D model visualisation, giving a graphical view of complex asset structures as a complement to the information managed in AccurAPM. Integrity data is located on the 3D plant model, so equipment can be found visually rather than only through the asset hierarchy.

AccurPulse adds AI-assisted interaction and data extraction to AccurAPM. An AI Copilot lets users interact with enterprise data, including CMMS information, through a private, secure assistant. Analysis can run across the full system or be limited to a defined scope using Query Composer, and AI-based extraction turns PDF drawings into structured records.

In an on-premises deployment your data never leaves your network. AccurPulse runs inside your own infrastructure, and the AI Copilot works on enterprise data held there. Access follows the roles, sites and data permissions already configured in AccurAPM Core, so a user sees through AccurPulse only what they are permitted to see.
