Welcome to GGS Oil & Gas Systems


Some follow the road, others lead the way!

This is exactly what GGS stands for. We lead the way in the design, production and implementation of complete integrated flow metering solutions (custody or non-custody! ), LNG sampling systems or a combination of both. Furthermore GGS has competence and experience in gas filtration, pressure reduction, flow control , gas treatment,… In short, GGS is a ONE STOP SHOP company.

Teamwork makes the machine work! Cohesive in engineering, in-house specialists over the different engineering branches, proven track records a huge installed base,… your gas and LNG projects are in good hands! 

GGS Oil & Gas Systems provide turnkey solutions including:
  • Fully integrated metering skids
    • Flowmeters (Ultrasonic, Turbine, Coriolis Orifice, etc
    • Valves and piping

GGS leads the market in offshore FSRU/FLNG gas metering packages and LNG sampling sysystem having an offshore installed base of over 60 revamped and New Built installations (Send out, BOG, LNG, DFDE …. ect. )

An offshore metering skid often has an integrated facility for proving, sampling and analysis and a common metering control system.

What makes off-shore different ?

Offshore Gas Metering Systems are characterized as the most challenging metering designs.

To keep safety high, operating and maintenance costs low, special requirements for these offshore installations must be met. Robustness is key, corrosion resistance, on time delivery, redundancy, highest accuracy, minimum weight as well as space-saving designs for all equipment.

GGS has the skills and know-how to successfully conquer these industry challenges while providing technically sound solutions.

To obtain an accurate analysis of LNG, it is essential to have the right sampling system

Accurate and traceable determination of LNG compositions is crucial for custody transfer

For natural gas, the most widely used method to determine the gas composition is using a calibrated gas chromatograph (GC),

However, when it comes to sampling LNG the process has more than a few challenges.
For natural gas, the most widely used method to determine the gas composition is using a calibrated gas chromatograph (GC),

For a reliable and accurate LNG sampling system the expertise of GGS is required.
