Suncor Energy Inc. contacted Synodon as part of an effort to enhance pipeline leak detection. Ideally, Suncor needed a technology that could detect natural gas as well as liquid hydrocarbon releases. Synodon’s new technology is an aircraft mounted gas remote sensing instrument that has been used for detecting leaks from natural gas pipelines for over four (4) years and was expanding their capability to include liquid hydrocarbons. This paper will describe the steps that Suncor and Synodon have taken over the last two years to develop and validate this detection technology. Synodon completed a number of studies including laboratory and field tests that demonstrated the ability of Synodon’s technology to remotely detect ground-level plumes of vapours released from a liquid hydrocarbon pipeline. Synodon conducted full atmospheric analytic modeling followed by laboratory measurements to determine the level of sensitivity of its instrument measurement to both methane and various liquid hydrocarbon vapors including gasoline, condensates and synthetic crude oil. Suncor participated in the development of test methodology and field execution in order to witness and validate the results. Based on this work, Suncor has determined an optimum inspection frequency based on theoretical spill size, SCADA leak detection thresholds and conventional aerial patrol constraints. The results and conclusions of this work will be presented.

The reduction of Non-Revenue Water (NRW) through leakage detection is gaining ever higher significance for well-run water utilities. Tethered leak detection technology has become an essential tool for detecting the presence pinpointing the location as well as estimating the magnitude of leaks in large diameter (300 mm and above) water transmission mains of all pipe materials. For the past 7 years, inline CCTV inspection has also been available for in-service water mains using the Sahara® tethered video inspection system. These two technologies were used independently, which required two surveys for the same pipeline to deliver leak detection and CCTV inspection. This paper introduces Sahara AV, tethered combined leak detection and CCTV inspection technology designed to deliver multi functions such as leak detection, leak location and CCTV inspection through only one deployment for in-service water mains; recently wall thickness assessment has also been added to the list of technologies which can be mounted on the Sahara system. This paper introduces the Sahara AV system along with its specifications and explains the mechanism adopted to introduce the sensor into the live pipeline. The paper also discusses Sahara case study from Asia describing the benefits and return on investment experienced by clients that have engaged with programs involving Sahara technology.

Pipelines leaks normally begin at poor joints, corrosions and cracks, and slowly progress to a major leakage. Accidents, terror, sabotage, or theft are some of human factor of pipeline leak. The primary purpose of Pipeline leak detection systems (PLDS) is to assist pipeline operators in detecting and locating leaks earlier. PLDS systems provide an alarm and display other related data to the pipeline operators for their decision-making. It is also beneficial because PLDS can enhance their productivity by reduced downtime and inspection time. PLDS can be divided into internally based or computational modeling PLDS Systems and external hardware based PLDS. The purpose of this paper is to study the various types of leak detection systems based on internally systemtodefine a set of key criteria for evaluating the characteristics of this system and provide an evaluation method of leak detection technology as a guideline of choosing the appropriate system.
