Leak Detection and Repair (LDAR): Principles, Practice, and Optical Gas Imaging 

Presenter: Rob Griffiths – Founder & CEO, OSS Enviro 

Part 1 – Introduction (15 mins) 

• Welcome & objectives of the session 

• Why LDAR matters: compliance, environment, cost savings 

• Overview of global drivers (methane regulations, OGMP 2.0, ESG pressures) 

Part 2 – LDAR Fundamentals (30 mins) 

• What is LDAR? Purpose and process 

• Regulatory frameworks (EPA, EU Methane Strategy, OGMP 2.0) 

• Key terminology: leaks, fugitive emissions, VOCs, quantification 

• Traditional methods vs modern approaches 

Part 3 – Optical Gas Imaging (45 mins) 

• What is OGI? How the technology works 

• Types of OGI cameras (EyeCGas Multi, EyeCGas Mini, MetCam etc.) 

• Advantages over traditional methods (speed, safety, coverage) 

• Demonstration videos/images of OGI in action 

• Quantification: moving from detection to measurement 

Break (15 mins) – tea/coffee, informal discussion 

Part 4 – Methane Slip (15 mins) 

• What is methane slip and how it differs from fugitive emissions 

• Sources (engines, turbines, flares, incomplete combustion) 

• Detection challenges & regulatory relevance 

• Role of OGI and monitoring in identifying methane slip 

Part 5 – Implementing LDAR Programs (30 mins) 

• Designing an LDAR program (frequency, scope, equipment) 

• Integration with drones, continuous monitoring, and handheld OGI 

• Data collection, reporting, and compliance documentation 

• Best practice tips & case studies 

Part 6 – LDAR in Practice (20 mins) 

• Live case study walkthrough (real-world example) 

• ROI: cost of leaks vs savings from repairs 

• Linking LDAR to ESG goals and investor reporting 

Part 7 – Q&A / Wrap-up (20 mins) 

• Open Q&A session 

• Key takeaways 

• Further resources & training opportunities
