OIL AND GAS, Eaubonne


A gas is defined as a substance that has no definite shape nor volume. Thus, the chemical characteristics and properties vary greatly from one gas to another. Most industries produce or use specific gases. A minimum level of knowledge on these gases is, therefore, required to protect oneself in the best possible way.

Knowing the gas’ physical-chemical properties and the effects of some concentrations on health is a first step to protecting yourself against possible hazards. For optimal protection, however, an accurate measurement of these concentrations using gas detectors (through personal protective equipment or fixed installations) and adapted breathing protection equipment (air-purifying and/or self-contained respiratory protection) is also necessary.

Fixed Gas Installation Saint-Denis

Highly active in this field, we handle the maintenance of gas detectors on BP (DELEK France) and TOTAL DISTRIBUTION’s (SCDP DOUALA Cameroon) oil depots.

We also operate offshore in Cameroon.

Our objective is to provide full coverage to Central Africa : Equatorial Guinea, Gabon, Tchad and Congo. Due to our proximity, we have opened a maintenance and training workshop in Douala Cameroon. 

Talks are also underway for projects with the Croatian National Hydrocarbons Company (INA) and with BOSNIA Herzegovina’s refinery (BOSANSKI BROD).
