Leak Detection

and Repair

(LDAR) Program

There is a need for regular inspection of fugitive emissions from leaks, in the form of volatile organic compounds (VOC).

LDAR is a work practice designed to identify leaking equipment so that emissions can be reduced through repairs. A component that is subject to LDAR requirements must be monitored at specified, regular intervals to determine whether or not it is leaking. Any leaking component must then be repaired or replaced within a specified time frame.

LDAR is mainly carried out in chemical industries, refineries and oil & gas industries. Riverstone has provided VOC leak inspection and training services to a wide range of clientele including Petronas Group HSE, Petronas Gas Berhad, Petronas Chemicals Group Bhd and Petronas Carigali Sdn Bhd. The field inspections involve use of the infrared (IR) cameras for quick and efficient operation.

What is Optical Gas Imaging (OGI)?

“Optical Gas Imaging (OGI) cameras use spectral wavelength filtering and sterling cooler cold filtering technology to visualize the infrared absorption of VOC/Hydrocarbon, SF6, refrigerants, Carbon Monoxide and other gases whose spectral absorption matches the response of the camera.”
