Review design data
The study pulled design, material, pressure, and installation information to define the technical basis of the PE pipeline system before risk scoring.

Risk Assessment for PE 180 mm Jargas Pipeline
A structured risk assessment for an existing gas distribution pipeline, focused on probability of failure, consequence mapping, and practical mitigation priorities.
Project Overview
What this project covered
This project was developed to evaluate the integrity and operating risk of an existing PE 180 mm gas distribution pipeline in Surabaya. The work centered on design data review, management-risk framing, and qualitative-to-quantitative risk logic so the client could gain a clearer basis for safety decisions and technical follow-up.
Work Scope & Method
How the assignment was executed
Visual inspection and minimum-distance survey
Field inspection was used to verify the actual condition of the buried line and to review surrounding exposure and right-of-way context.
Risk scoring and capability review
Probability and consequence of failure were assessed and translated into a practical recommendation set for safer continued operation.
Context and delivery pressure
The pipeline required a stronger risk narrative that could bridge design assumptions, field condition, operational control, and documented safety obligations without turning the assessment into a disconnected compliance exercise.
How the work was structured
We organized the work around failure-factor breakdown, probability and consequence scoring, and a readable risk summary that supported inspection planning and mitigation prioritization for continued operation.
Key Findings
Important technical takeaways
The pipeline still sits within a clearly defined design envelope
The report records stable design data for material, wall thickness, pressure range, and MAOP, which makes the risk narrative easier to communicate in the web UI.
Risk control depends on field awareness and operational discipline
The study places strong emphasis on surrounding exposure, underground utility mapping, and leak detection during early operation.
Deliverables

Recommendations
Practical follow-up priorities
Educate nearby residents about hazardous areas and possible failure scenarios during pipeline operation.
Re-evaluate pressure control and safety systems so no pressure excursion exceeds the original design basis.
Apply strict document control and review operational-event history regularly.
Map and mark all underground utilities correctly.
Run intensive leak survey during the early operation phase.
