The primary purpose of leak detection systems (LDS) is to help pipeline controllers to detect and localize leaks. LDS provide alarms and display other related data to the pipeline controllers to assist decision-making. Pipeline leak detection systems can also enhance productivity and system reliability thanks to reduced downtime and inspection ...
Distributed fiber-optic sensing technology can be used for leak detection through DAS and DTS. [26] AP Sensing has a regional office in Bahrain, and operates throughout the Middle East. [27] Their Distributed Fibre Optic Sensing is designed to monitor pipeline leaks, and is used by the Kuwait Oil Company and the Abu Dhabi National Oil Company.
December 27 – A leak was detected on a 16-inch pipeline, in St. Bernard Parish, Louisiana. About 350,000 gallons of low sulfur diesel were spilled. That section of pipe had corrosion thinning, and the leak detection system for the pipeline did not fully indicate a leak.
A hydrostatic test is a way in which pressure vessels such as pipelines, plumbing, gas cylinders, boilers and fuel tanks can be tested for strength and leaks. The test involves filling the vessel or pipe system with a liquid, usually water, which may be dyed to aid in visual leak detection , and pressurization of the vessel to the specified ...
To optimize and secure the operation of these assets, some pipeline companies are using what is called "Advanced Pipeline Applications", which are software tools installed on top of the SCADA system, that provide extended functionality to perform leak detection, leak location, batch tracking (liquid lines), pig tracking, composition tracking ...
It also announced plans to change the environment in the pipes with continuous corrosion inhibitor added directly to the transit lines and with water or sediment buildup addressed with weekly maintenance pig runs; a new leak detection system; and new pig launchers and receivers in all segments of the transit lines, giving BP the capability to ...
A scraper pig shown at the Trans-Alaska Pipeline System Visitors Center. In pipeline transportation, pigging is the practice of using pipeline inspection gauges or gadgets, devices generally referred to as pigs or scrapers, to perform various maintenance operations. This is done without stopping the flow of the product in the pipeline.
The basic principle is that the magnetic field "leaks" from the steel at areas where there is corrosion or missing metal. To magnetize the steel, a powerful magnet is used. In an MFL (or Magnetic Flux Leakage) tool, a magnetic detector is placed between the poles of the magnet to detect the leakage field.
