Petroline Engineering
Petroline Composite Repair System on OLNG Pipeline

Petroline CompositeRepair System

High-performance composite repair technology engineered for OLNG pipelines and pressure vessels — restoring structural integrity without hot work on live, pressurized systems.

Fully compliant with ISO 24817 and ASME PCC-2, our composite repair solutions deliver a 25+ year design life with cold-applied installation safe for Zone 1 and Zone 2 hazardous LNG areas.

APPLICATION PROCESS

DEFECT ASSESSMENT

Detailed wall thickness measurement and defect characterization using UT and visual inspection before repair engineering commences on the OLNG asset.

REPAIR ENGINEERING

ISO 24817 / ASME PCC-2 engineering calculations defining composite thickness, layer schedule, and qualified WPS for the specific OLNG operating conditions.

SURFACE PREPARATION

Abrasive blast to SSPC SP-10 near-white metal standard and primer application to maximize composite-to-pipe adhesion and long-term bonding performance.

COMPOSITE APPLICATION

Systematic layer-by-layer laminate wrapping by certified applicators following the approved repair procedure specification and quality plan.

QA & DOCUMENTATION

Shore D hardness testing, holiday detection, and full as-built repair report delivered with every completed installation for OLNG operator records.
