De

sig

n Various National and International codes like ASME B31.4, API 1104, API 1102, API 5L,

Petroleum Rules 2002, OISD 141, 117, 214

Corrosion Allowance of 0.5 MM

Safety Factor of 0.72 as per ASME B31.4

Str

ength

Selection of line pipe based on API 5L standard spec

Automatic / Semi-Automatic welding ensuring strength of weld area greater than parent material

100% Radiography is ensured for the weld joints as per API 1104

Pipeline is shop floor tested at 95% of SMYS

Pipeline is site tested at either 1.25 times the design pressure or 95% of SMYS

Concrete coating of Pipes as anti-buoyancy measure

Sa

fety

The pipeline routes are selected based on urbanization and population

Laid at the minimum depth of 1.2 Meters

Environmental Impact assessment (EIA) and Quantitative risk analysis (QRA) studies

Higher wall thickness in Highway and Rail Crossings with casings ref. API 1102

Pipeline Laid 2 Meters below the Scour Depth using HDD while crossing Perennial rivers

Adequate safety margins considered for withstanding longitudinal stresses because of earthquakes / Tectonic Plate Movement

Mobile Cold Flare Systems for LPG Pipelines at Remote SVs

Corrosion Protection

Process Control

Safety/Security

Emergency preparedness

Internal corrosion:

� Dosing by Corrosion Inhibitor� Online Corrosion

Monitoring using Corrosion Probes

External corrosion:

� Anti corrosive coating using Denso/ 3 LPE coating.

� Corrosion protection thru Impressed Current Cathodic Protection

system

� PLC based onsite

control of various process and equipment parameters

� OFC Based dedicated telecommunication system for effective and

quick communication between stations.

� SCADA based control

of entire pipeline for control of Process and equipment

� Dynamic and Steady state leak detection system based on

mathematical model of Pressure, temperature, volume and flow.

� Day and Night Patrolling of Line walkers

� CCTV Cameras in all stations and SV stations

� Security Tracking System to monitor the movement of line

walkers on a daily basis

� Pipeline Intrusion

Detection System to detect third party intrusion on our

pipeline ROU

� Offsite and On Site mock drill

� Village awareness and

Village coordination meet

� Security Coordination
