LDAR & Optical Gas Imaging Surveys

LDAR & OGI Surveys

Our LDAR (Leak Detection and Repair) inspection services provide advanced methane and gas leak detection solutions for the biomethane, biogas, and wider gas industries. Using the latest FLIR cooled Optical Gas Imaging (OGI) cameras, including highly sensitive FLIR GF-series technology, we are able to rapidly identify fugitive emissions and gas leaks that are invisible to the naked eye. Our inspections help operators improve environmental performance, reduce product loss, enhance site safety, and support ESG and regulatory compliance objectives.

All inspections are carried out by experienced and certified thermologists with extensive technical knowledge of biomethane and anaerobic digestion operations. This sector-specific expertise allows us to understand the unique operational challenges associated with digesters, upgrading plants, compressors, flare systems, gas handling infrastructure, and associated process equipment. We deliver practical, detailed inspections with clear reporting and prioritised recommendations to support effective maintenance and emissions reduction programmes.

To provide the highest level of detection capability and confidence, our OGI inspections are supported by FLIR quantification software and VOC sniffing technologies for enhanced leak verification and assessment. This combination of advanced equipment and industry expertise enables us to deliver accurate, reliable, and independent LDAR services tailored to the needs of modern gas infrastructure operators across the UK and Europe.
