With a significantly lower carbon footprint than coal and oil, natural gas and LNG play a critical role in the global energy transition and energy security. As liquefaction capacity expands worldwide, you must ensure product quality, process efficiency and compliance across increasingly complex and geographically dispersed supply chains.
We support you at every stage of the natural gas and LNG value chain – from production and gas treatment to liquefaction, storage and transport. Our independent inspection, testing and certification services provide reliable, unbiased and validated data, from ISO17025 accredited laboratories, enabling you to make informed operational and commercial decisions with confidence.
Ensure quality and process control across the gas value chain
- Verify gas composition and propertiesConfirm permanent gases, hydrocarbons and critical physical properties, such as calorific value, Wobbe Index, density and hydrocarbon dew point, using ISO 6974, ISO 6976, GPA 2286 and GPA 2261 methods.
- Monitor impurities and contaminants
Detect and quantify traces of sulphur (including H2S) and mercury to protect process installations and reduce risk.
- Support gas treatment and liquefaction processesAnalyze cleaned gas streams, NGL (natural gas liquids) products such as ethane (C2), propane (C3), butane (C4) and natural gasoline (C5+), and monitor alkanolamine and dehydration systems.
- Deploy compliant on-site laboratory solutions
Benefit from the presence of a fully QHSE compliant on-site laboratory at your gas-treatment- and liquefaction plant in both on- and off-shore production locations.
- Optimize amine and dehydration systemsImprove operational performance through expert troubleshooting, process optimization studies and targeted engineering support.
- Strengthen LNG operational knowledgeEnhance internal expertise through structured, interactive LNG training programs covering safety, cargo handling and custody transfer.
Comprehensive on-site laboratory services
- On-site laboratory deployment and managementDesign, install and operate permanent or mobile laboratories, including technician mobilization and implementation of laboratory and QHSE procedures.
- Natural gas compositional and physical property analysisLaboratory determination of permanent gases, hydrocarbon profiles, calorific value, Wobbe Index, density and hydrocarbon dew point, accredited to ISO17025.
- Trace contaminant analysisQuantification of sulfur species and mercury impurities in accordance with industry standards.
- Gas treatment and liquefaction process monitoringAnalytical support for treated gas and NGL streams, including alkanolamine system analysis and dehydration performance verification.
Build operational confidence through LNG training
In association with IDESS Interactive Technologies, we offer online, interactive LNG training across seven dedicated modules, including:
- Introduction to LNG
