LNG storage and fireproofing program

2026-09-02 · Cryogenic piping, cold boxes & PFP steel (NFPA 59A / API 2218)

Measured outcomeEvery fireproofed zone and CUI suspect area ranked by consequence and tied to turnaround scope.

An LNG liquefaction and export facility needed to govern two high-consequence programs that traditional IDMS tools treat as side checklists: passive fire protection (PFP) across structural steel and vessel skirts, and corrosion under insulation (CUI) on cycling cold and ambient piping.

Both programs generated thousands of visual observations, thermal scans, and pulsed-eddy-current (PEC) readings that sat in contractor slide decks rather than on the equipment hierarchy.

Current state before intelliSPEC

  • Install-and-forget fireproofing: Cementitious and intumescent fireproofing zones lacked an asset-level register tracking UL 1709 rating, required thickness, cracking or delamination grade, and corrosion under fireproofing (CUF).
  • Blanket insulation stripping: Without a structured record of wet insulation, jacketing breaches, and NDE screening results, turnaround planners stripped insulation by calendar age rather than measured CUI risk.
  • No spatial context: Planners reviewing repair scope could not see which degraded PFP zones sat inside the same fire scenario or pipe rack bay.

Configured path

The facility deployed intelliFIRE, intelliINSPECT, intelliPAINT, and intelliPROJECTS on top of the intelliVISION 3D asset model, with field capture in intelliEDGE.

  1. Fireproofing register on the twin: Every structural column, vessel skirt, and emergency-shutdown valve zone was registered in with its fire scenario, UL 1709 / ISO 22899 rating, and required thickness.
  2. Offline CUI and CUF workflows: Inspectors walked pipe racks offline with , logging jacketing damage, moisture intrusion, and PEC screening calls per API 583 and API 2218.
  3. Consequence-ranked repair handoff: Degraded PFP zones and confirmed CUI locations routed directly into turnaround work packages, prioritized by fire consequence and remaining wall margin.

Measured outcome

  • Targeted insulation and PFP repair: Scaffold and stripping hours focused on verified moisture and CUF anomalies rather than blind footage quotes.
  • Defensible NFPA 59A and Part 193 evidence: Fire-barrier integrity, inspection intervals, and recoating closeouts are retrievable by zone and asset tag at any regulatory review.
  • Closed loop from visual flag to recoating: Every stripped CUI area carried its UT wall reading, repair record, and recoating sign-off on the same component.
