Leak Detection Going to the Dogs

Dogs can perform a multitude of services including protection, therapy, rescue, and tracking to name a few. They can be trained to detect virtually anything, including pipeline leaks.

Pipe Pressure Before Explosions was 12 Times too High

The pressure in natural gas pipelines prior to a series of explosions and fires in Massachusetts last week was 12 times higher than it should have been, according to a letter from the state's U.S. senators to executives of the utility in charge of the pipelines.

Official: Pressure Sensors Focus of Gas Explosions Investigation

The investigation into the Boston-area natural gas explosions is partially focused on pressure sensors that were connected to a gas line that was being taken out of service shortly before the blasts, the head of the National Transportation Safety Board said.

California Jury Finds Plains All American Guilty in Oil Spill Trial

A California state jury found Plains All American Pipeline guilty of criminally fouling state waters or harming wildlife in a 2015 oil spill along the Pacific Coast.

Securing Open SCADA Systems for Pipeline Operations

Traditional SCADA systems used pipeline operational control are vulnerable in at least three main areas: operational information, production data and control logic. The more openly this data flows, the more cost-effectively the plant can be run, so there is much to be gained by securing the data exchange.

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.

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.
