You Do Leak Detection, but Do You have Breach Detection?

Pipeline companies invest considerable effort preventing, detecting, and responding to leak incidents, but are they investing enough effort preventing, detecting, and responding to cybersecurity incidents? Since, in principle, a cyber-incident could lead to a leak incident, companies should consider breach detection as part of their overall leak prevention program.

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.
