Pergam Technical Services is a subsidiary office of Pergam-Suisse AG based in Zurich, Switzerland, that specializes in equipment and services for aerial and vehicle-based natural gas leak detection. We are also experts in aerial power line inspections with FLIR IR thermography, UV corona inspections, gyrostabilized platforms / gimbals.
We offer the following services
- Gas leak detection with ALMA (Airborne Laser Methane Assessment) and SELMA (Street Evaluating Laser Methane Assessment)
- Thermography services with analysis and documentation
- Analysis of thermal problems
- Airborne recordings of daylight and infrared video and pictures from the helicopter camera systems using gyro stabilized camera systems (Unique: We also provide radiometric infrared images with our HELIVISION system!)
Gas Leak Detection
Fossil energies like oil and natural gas and their availability are crucial for industries and households in all parts of the modern world. Their transport and distribution in high volumes ensures economic stability, mobility and comfort to billions of people. In order to guarantee a constant supply, huge pipelines and distribution networks are established, but there are also risks involved. Natural gas leakage from pipelines is not only wasteful but poses a real danger and coupled with the obvious threat to the environment, renders it imperative that these worldwide networks are consistently monitored.
A distribution network for natural gas consists of an intricate number of components such as valves, compressor stations, meters and many thousands of miles of both steel and plastic pipelines. The effective monitoring of such a network can be exceedingly difficult, especially in remote areas.
Department of Transportation regulations require operators of natural gas facilities to implement safety management programs, which include regular patrolling and leak surveying of pipeline networks.
Pergam-Suisse AG has introduced a solution to pipeline patrolling and leak surveying. Both the ALMA and SELMA systems represent a revolutionary new pulsed laser leak detection system that facilitates an efficient, fast, sensitive and economical inspection method.
This method of detection will enhance safety and reliability resulting in an increase in efficiency of the whole natural gas transport system. Its primary application is leak detection in natural gas gathering, transmission and distribution pipelines. Additional areas of inspections include metering stations, regulator stations, odorizer stations, compressor stations, valves, storage facilities and any other potential sources of methane emissions to the atmosphere.
