Thousands of miles of natural gas pipelines in Massachusetts are leak-prone and need repair, utilities have told state regulators, highlighting aging energy infrastructure risks after explosions ripped through three towns outside of Boston this week.
Dozens of Gas Blasts Rock Boston Suburbs, Killing at Least 1, Injuring 12
Dozens of explosions, apparently triggered by a natural gas pipeline rupture, rocked three communities near Boston on Thursday, killing at least one person, injuring 12 and prompting the evacuation of hundreds, officials said.
Unconventional Well Demands and EOR Drive Innovation in Subsea Sealing Technology
As the subsea industry continues to evolve to help meet the demands of oilfield operators, there is now an even greater requirement for ground-breaking sealing technology.
Preparing Pipelines for Successful In-Line Inspection
Gauge pigs provide insight into some conditions inside the pipe, but not all of them. They’re not intended to measure pipeline cleanliness or indicate if debris has built up to the point that it will impair the inspections tool’s data-gathering capabilities.
Pipeline Digs Get Assist From PMO
Performing direct assessments to verify a pipeline’s MAOP is not new, but as federal regulations become more stringent, the volume of digs will increase significantly, and operators need to keep up with the pace.
NACE President Looks to Bolster Corrosion Education
NACE International’s president for 2018, Jeffrey Didas, discusses corrosion education and other issues of importance to the organization in its 75th anniversary year.
Making Simple Smart and Smart Simple: Cost-Effective, Low-Risk Pipeline Inspection
Three brief case studies highlight the challenge, solution and outcome where innovative pigging solutions have been successfully deployed to meet major offshore operator’s requirements.
Introduction to Vibration-Based Leak Detection Technology
There are various technologies available in the market for pipeline leak detection and loss monitoring. While leak detection system cannot reduce the probability of a leak, using the appropriate system for a pipeline can significantly reduce the risk of a leak and rupture.
In-Line Inspection of Low-Pressure, Low-Flow Gas Pipelines
Maintaining control of an In-Line Inspection (ILI) tool’s speed is one of the most critical elements in successfully assessing the condition of a pipeline. Success is defined as receiving an intact tool at the conclusion of the inspection and acquiring data of sufficient quality to achieve the vendor’s sizing and accuracy specifications.
Accessible Pipeline Data Becomes Focal Point of Safety
Many of the world’s most vulnerable pipelines are in developed and municipal areas, where it can be difficult to locate miles of gas pipelines in these regions. And where locations exist, the data may not be in an easily retrievable and shareable format.
Gas Pipeline Issues Blamed for Malaysia's Falling LNG Exports
Malaysia's LNG exports fell to a four-year low in July as domestic gas pipeline issues plaguing the country since January took their toll, according to industry sources and Thomson Reuters data.
Enbridge, Baker Hughes Partner on Enhanced Inspection for Pipeline Safety
Enbridge and G.E. company Baker Hughes launched testing of new, ultrasonic phased array pipeline inspection tool sensors designed to enhance accuracy and identification of crack features and to deliver greater detail on the condition of a pipeline.
Instrument Simplifies Flow Data Control in Oil and Gas Operations
The Thermo Scientific AutoXP flow computer incorporates the functionality of a smart multi-variable transmitter in a single unit to simplify the generation, management and interpretation gas and liquids flow data in harsh operating environments.
Platform Simulates Pipeline Network
Elsyca V-PIMS is a graphical simulation platform for the integrity management of pipeline networks with respect to external corrosion. The platform simulates and visualizes the CP health status of the entire network based on known design information.
Chinese Pipeline Selects Rotork ELB for Increased Line Break Safety
The Rotork Electronic Line Break (ELB) is a self-contained system that continuously monitors pipeline pressure dynamics to provide early detection of pipeline breaks and initiate automatic valve actuator movement to a pre-selected emergency position.
Closer Look at Flammability, Inerting of Complex Hydrocarbon Mixtures
In the lifetime of oil and gas pipelines there are numerous events that could pose the potential of an explosion hazard. In case of air purging, flammable mixtures are created in pipelines in an uncontrolled manner. This article covers basic flammability and inerting principles and applications of mobile nitrogen unit technology has been proven safer than air purging while maintaining high operational flexibility.
Safety Board: Damage During Installation Led to Pipeline Crack
The NTSB said last year’s rupture of the Keystone oil pipeline in South Dakota was due to a fatigue crack that probably resulted from mechanical damage by a metal-tracked vehicle during installation.
Integrity Management of Unpiggable Pipelines
The long-term integrity of pipelines often depends on the ability to inspect their entire lengths with ILI technologies. When construction or location specifics prevent use of ILI, however, managing the short-term integrity of the pipeline becomes a higher priority until it can be made piggable.
Unidirectional Composite Repairs: A One-Way Approach to Failure
Composites can be easily over-summarized, in the same way a layman may state that all pipes are just metal. The author sets the record straight on one common design choice: using unidirectional strands or fabrics.

Examining the ability of robotic pipeline inspection methods to address specific pipeline threats, including surface corrosion, internal and external anomalies, deformations, construction features, and other useful pipeline features and characteristics.
Tunnel, Trench Offer Options for Replacing Pipeline
A 65-year-old pipeline that carries crude oil beneath a sensitive waterway connecting two of the Great Lakes could be replaced with pipes buried in a tunnel or partially enclosed in trenches that would pose virtually no risk of leakage but require years and hundreds of millions of dollars to build, according to a report released Friday.
