What is Gas Leak Detection and Repair (LDAR)?
Leak Detection and Repair (LDAR) is crucial for finding and quantifying gas leaks to reduce environmental impact and enhance regulatory compliance. It’s particularly important in oil, gas, and marine industries, where managing emissions is essential.
Gas leaks can occur in various locations, including:
- Machine bases and pipework
- Storage vessels
- Engines
- Supply lines
- Kilns
LDAR monitoring detection is suitable for any sector that uses gas as a fuel source, including natural and man-made gases. So, whether you’re a manufacturing plant, a power station, or a large-scale oil and gas company, we can tailor our services to meet your needs. We’ll work with you to create an LDAR programme based on your industry requirements, considering everything from your specific operations to regulatory obligations
Who can benefit from LDAR services?
LDAR can be applied to key industries such as:
- Manufacturing
- Production
- Power stations
- Refineries
- Oil and Gas
- Marine and offshore
Our LDAR services cover methane detection—a major contributor to greenhouse gas emissions. Our expertise in this area means you can identify methane leaks easily and take immediate action to support your sustainability goals. With BES Group, you can effectively manage gas emissions and detect costly leaks to reduce risks to your operations. Our LDAR services help you improve operational efficiency and contribute to a cleaner, more sustainable future.
Why is methane gas leak detection important?
Methane is a potent greenhouse gas therefore addressing methane emissions is essential for meeting environmental goals.
Investing in methane detection isn’t just about emissions targets—it’s also a proactive move toward sustainability and operational efficiency. Prioritising methane leak detection can drive your commitment to environmental sustainability and enhance your business’ resilience.
There are two key initiatives that highlight the importance of methane detection:
OGMP 2.0 (Oil and Gas Methane Partnership 2.0)
The OGMP 2.0 initiative brings together oil and gas companies that want to reduce methane emissions. It involves sharing best practices in leak detection and repair. Participating businesses can enhance their reputation and align with global climate goals, making advanced methane detection a priority.
MAMII (Methane Action and Monitoring Initiative)
MAMII promotes improved methane monitoring and reporting standards across industries. This initiative promotes innovative technologies for accurately measuring methane, enabling businesses to understand and reduce their methane emissions.
Gas Leak Detection and Repair (LDAR) process
At BES Group, we guide you through identifying the source of gas leaks and provide tailored recommendations for effective solutions. Our comprehensive LDAR process ensures you receive the highest level of service and accuracy.
- OGI survey (Optical Gas Imaging):
We conduct an OGI survey using advanced cameras to detect gas leaks. Our superior-quality cameras offer unparalleled accuracy and precision in quantifying leaks to get right to the source of the problem. - Isolate and tag off:
Once we’ve detected leaks, we isolate and tag the affected areas to quantify the amount of gas leakage accurately. This step is crucial for understanding the extent of the issue and planning effective repairs. - Leak detection survey:
Our thorough leak detection survey includes videos, images, and quantification levels, along with clear recommendations for next steps. You can view all findings in a convenient online report, making it easy to review and take action.

How is liquified natural gas produced?
+
Liquefied natural gas (LNG) is produced through a process called liquefaction, which involves cooling natural gas to approximately -162°C. This temperature reduction transforms the gas into a liquid, reducing its volume approximately 600 times, making it easier to transport and store. The production process typically involves removing impurities, such as water and carbon dioxide, before cooling the gas. Once liquefied, LNG can be transported in specialised cryogenic tankers for use.
What are volatile organic compounds?
+
Volatile organic compounds (VOCs) are organic chemicals containing carbon and with a high vapour pressure at room temperature. This allows them to evaporate easily into the air. VOCs include a variety of substances found in everyday products such as:
- Benzene: Often found in gas and industrial emissions.
- Formaldehyde: Used in building materials and household products.
- Toluene: Commonly used as a solvent in paints and coatings.
VOCs can have adverse health effects and contribute to air pollution, so regulating and monitoring their use is crucial.
How are volatile organic compounds produced?
+
Volatile organic compounds (VOCs) are produced from both natural and human-made sources, including:
- Industrial processes: Emitted during the manufacturing of paints, solvents, and plastics (e.g., toluene, xylene).
- Vehicle emissions: Produced by combustion engines in cars and trucks, contributing to air pollution.
- Household products: Found in cleaners, air fresheners, and personal care items, often evaporating into indoor air.
- Natural sources: Emitted by plants, with terpenes contributing to natural scents.
VOCs pose significant environmental concerns. They can contribute to ground-level ozone formation which worsens air quality and creates health risks, including respiratory issues. They can also act as greenhouse gases—known for impacting climate change.
What does LDAR stand for?
+
LDAR stands for Leak Detection and Repair. It was developed in the 1970s to address environmental and health concerns relating to industrial emissions. It’s a systematic approach to identifying and addressing gas leaks, particularly focusing on volatile organic compounds (VOCs) and methane emissions. LDAR is essential for environmental protection, especially in industries such as oil and gas. If you’re looking for expert LDAR services, contact BES Group via our online form.
What is an OGI camera?
+
An Optical Gas Imaging (OGI) camera is a thermal imaging device used to detect and visualise gas leaks, including methane and VOCs. It’s used for the following:
- Gas leak detection: OGI gas imaging cameras provide real-time visuals of gas emissions, allowing for quick identification of leaks.
- Safety enhancement: Optical gas imaging helps mitigate risks of hazardous gas exposure, improving workplace safety.
Where do gas leaks commonly occur?
+
Gas leaks can occur in various settings, leading to safety hazards and operational inefficiencies. Common examples include:
- Manufacturing facilities: Gas leaks often happen where natural gas or fuels are used in production processes, machinery, and heating systems.
- Refineries and chemical plants: These facilities are prone to leaks in storage tanks, piping, and valves due to handling volatile substances.
- Power plants: Gas leaks can occur in combustion engines and boilers, particularly in natural gas-fired plants.
- Oil and gas operations: Exploration and extraction sites frequently experience leaks from equipment, pipelines, and storage facilities.
- Commercial kitchens: Gas leaks can occur from stoves, ovens, and appliances where natural gas is used for cooking.
