ISO 15926-13:2018

Overview

ISO 15926-13:2018 - Integrated asset planning life-cycle specifies an ontology and an XML exchange schema for asset planning data in process plants, including oil & gas facilities. The standard defines how to represent portfolio, programme and project plans, maintenance and modification schedules, calendars, temporal constraints and resource requirements to enable consistent exchange and integration of life‑cycle planning data across systems.

Key technical topics and requirements

• Ontology for asset planning: a formal semantic model for planning concepts (activities, schedules, resources, events, milestones, progress).
• XML schema for data exchange: an XML representation derived from the ontology for interoperable transfer between planning and scheduling tools.
• Plans and schedules: support for portfolio, programme, project, operational modification and maintenance planning.
• Temporal relationships and constraints: representation of succession links, lag, free and total float, dependency relationships, and calendar-aware timing.
• Activity and breakdown structures: activity decomposition, activity types, status, priority and classification (purpose, lifecycle phase, criticality, risk).
• Resources and consumption: specification of material, equipment and human resources, consumption profiles, available physical objects and cost references.
• Calendars and repeating periods: modelling of working days, repeating time periods/points and execution calendars.
• Interfaces: defined interfaces to systems that process work orders, purchase orders and scheduling applications.
• Progress tracking and usage: support for progress measurement, frontline dates and resource usage tracking.
• Reference linkage: ability to reference external standard class libraries (note: the standard references classes but does not itself define those standard classes).

Practical applications and users

ISO 15926-13 is designed for organizations that need integrated, interoperable planning across engineering, construction and operations:

• Plant owners/operators and maintenance planners managing shutdowns, turnarounds and ongoing maintenance
• EPC contractors and project planners coordinating multi‑discipline project schedules
• Scheduling and asset management software vendors implementing interoperable import/export
• System integrators linking planning, work‑order and procurement systems
• Data managers standardizing lifecycle planning data for analytics and reporting

Benefits include improved data consistency, reduced manual translation, better coordination across teams and systems, and clearer traceability of planning decisions.
