Pipeline leak detection methods compared
How mass balance, RTTM, statistical and pressure-wave methods differ, and why high-consequence lines pair them with external sensing.
Engineering Insights
Practical articles on pipeline leak detection, standards, fibre optic sensing and SCADA communications, drawn from the systems we design and deliver.
All articles
Leak detection and standards
How internal and external methods compare, what the standards and regulations actually require, and how to combine layers on high-consequence lines.
RTTM vs fibre optic leak detection: which fits your pipeline?
What each method sees, where each is blind, and when to use both: a side-by-side comparison for pipeline operators.
API RP 1130, API RP 1175 and 49 CFR 195.444: what each requires
Two recommended practices and one federal rule, often confused. What each covers, how they fit together and what to evidence.
Fibre optic sensing
How distributed fibre sensing works along a pipeline, and what drives the cost of installing it.
Fibre optic sensing for pipelines: DAS, DTS and DSS
How one optical cable detects digging, leaks, fire and ground movement along a pipeline, and what to check before you install it.
DAS pipeline monitoring cost: what drives the price
Why a price per kilometre misleads, where the real cost sits, and what to prepare before you ask for a quote.
Communications for remote sites
How to design a resilient SCADA network, and how to choose between SDH, IP/MPLS and radio.
Designing SCADA communication networks for remote sites
Ring protection, legacy interfaces, teleprotection and radio: lessons from SDH, utility and metro communications projects.
SCADA over MPLS, SDH or radio: choosing a network for remote sites
How SDH, IP/MPLS, MPLS-TP and radio compare for SCADA, teleprotection and legacy traffic, and how to migrate safely.
