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.

An airborne infrared laser leak detection technology is proposed to detect natural gas pipeline leakage by helicopter which carrying a detector that can detect a high spatial resolution of trace of methane on the ground. The principle of the airborne infrared laser leak detection system is based on tunable diode laser absorption spectroscopy. The system consists of an optical unit including the laser, camera, helicopter mount, electronic unit with GPS receiver, a notebook computer and a pilot monitor. And the system is mounted on a helicopter. The principle and the architecture of the airborne infrared laser leak detection system are presented. Field test experiments are carried out on West-East Natural Gas Pipeline of China, and the results show that the airborne laser leak detection method is suitable for detecting gas leak of pipeline on plain, desert and hills but unfit for the area with large altitude diversification.
