ISO 12736-2:2023 PDF

Overview

ISO 12736-2:2023 specifies project‑specific qualification processes for production and application procedures of wet thermal insulation systems used on pipelines (factory applied) and subsea equipment in the oil and gas industries, including lower carbon energy projects. The standard defines requirements for product and process qualification, production testing, inspection, documentation, handling and storage, and factory repair. It explicitly excludes pre‑fabricated insulation, pipe‑in‑pipe annulus insulation, maintenance works on installed wet systems, and qualification of anticorrosion coatings.

Key Topics and Requirements

• Project‑specific qualification: Defines how to qualify materials and application processes for a specific project before production and installation.
• Material classes: Introduces classification of insulation materials to guide testing and acceptance.
• Production qualification process:
  • Process descriptions and project considerations
  • Procedure qualification trials and pre‑production trials
  • Production testing and inspection requirements and traceability
• Application procedures:
  • Application Procedure Specification (APS) content (methods, equipment, tools)
  • Inspection and Test Plan (ITP) generation and required inspection documentation
  • Qualification of operators and personnel performing application
• Testing and measurement:
  • Detailed thermal conductivity (k‑value) testing requirements
  • Material and system tests as part of production verification
  • Project‑specific functional tests and fatigue testing guidance (annexes)
• Factory repair, handling and logistics: Requirements for damage assessment, repair testing, and handling/storage/transportation at coating yards and on‑site.
• Documentation and conformity: Final documentation, certificates of analysis and inspection records to enable traceability and conformity assessment.

Applications and Users

ISO 12736-2:2023 is intended for:

• Pipeline and subsea insulation system providers and manufacturers qualifying production and application procedures in a factory environment.
• Project purchasers, operators and end users who need to specify and verify project‑specific qualification requirements.
• QA/QC engineers, materials engineers and inspection teams responsible for test plans, operator qualification and traceability.
• Coating yards, subsea contractors and EPC firms managing factory applied wet thermal insulation for oil, gas and lower carbon energy installations.

Practical benefits include consistent qualification of wet thermal insulation, reduced field failures, clear supplier/purchaser expectations, and defensible records for commissioning and handover.
