Exploration and Production

The exploration - production activity is very often exercised in extreme environments (very low or very high temperatures and hygrometry, very strong precipitations...), so detection and fire fighting systems must therefore be very hardy to withstand these difficult environmental conditions. In addition, the offshore activity requires very restrictive marine certifications.

AUTOCHIM offers a wide range of products meeting these needs:

  • The detection of hydrocarbon gases and fumes is ensured by catalytic bead, infrared or ultrasonic point detectors. For perimeter surveillance, linear detectors are used such as NDIR, laser or optical fibre barriers (pressurised gas or liquid leaks on the pipeline).
  • For the detection of H2S, specific thin film semiconductor detectors (MOS) offer exceptional resistance to low and high temperatures and very dry or very humid atmospheres. These point detectors can be combined with laser linear detection. In addition, flame detectors allow any fire outbreak on installations to be anticipated.
  • For the protection of electrical rooms, AUTOCHIM offers early smoke detection systems (HSSD) to detect abnormal heating before a fire starts and thus act earlier to get the equipment to a safe place.

These detectors are installed in a fixed position and connected to a detection station that manages automatic controls such as flashing lights, sirens, power cuts. These stations also allow fire fighting installations to be managed by gas (CO2, NOVEC, Argon, FM200…) or by water and foam deluge.

For temporary installations AUTOCHIM offers detection markers to ensure site safety.

AUTOCHIM also offers a wide range of process analysers. In the gas phase, we offer H2S analysers by UV, laser or colorimetry and quartz or laser hygrometers. In the liquid phase, we offer analysers to trace hydrocarbons in the water by UV fluorescence so as to control aqueous effluents as well as vapour pressure analysers on light crude oil or condensates.

In addition, we have portable analysers for traces of oil in water (solvent-free method) as well as a portable hygrometer by laser.

Thanks to optical fibre, AUTOCHIM offers intrusion and malicious act detection systems thus monitoring zebra crossings, vehicles or machines over very large distances and differentiating them from background noise.

Moreover, AUTOCHIM accompanies you throughout your project: from advice and preliminary project audits, project monitoring within its Engineering department, commissioning as well as academic training courses or onsite training, to maintenance contracts and periodic audits.
