HydroFlash™ O2

Sonde optode d’oxygène dissous HydroFlash™ O2


La sonde Contros HydroFlash™ O2 est un capteur d’oxygène versatile dans les eaux peu profondes comme en océan profond, elle est utilisable en déploiement autonome comme intégré dans des ensembles de capteurs.


HydroFlash™ O2 est le choix parfait pour une variété de schémas de déploiement et de plateformes parmi AUV, ROV, gliders, bouées, rosettes et mouillages, etc.

Comment fonctionne-t-elle?


Cette sonde avancée est basée sur le principe de l’extinction de fluorescence. Les molécules d’oxygène dissous (O2) diffusent à l’intérieur d’un élément sensible abritant un colorant fluorescent. L’oxygène peut éteindre cette fluorescence en transférant l’énergie d’excitation depuis le colorant vers la molécule O2. Plus l’oxygène est présent dans l’eau plus faible est le signal de fluorescence mesuré.

Avantages
 Colorant à haute fluorescence est intégré dans un substrat solide courbe pour améliorer le rendement lumineux
 Temps de réponse court (T63<3s) combiné avec haute stabilité et précision
 Boîtier titane compact
 Robustesse, utilisable jusqu’à 6 000 mètres en immersion
 Très faible consommation d’énergie
 Versatile, facilement intégré dans tout ensemble ou plateforme en océanographie
 Mode veille programmable pour des déploiements étendus en mode autonome
 Logiciel complet pour programmation, transfert de données et visualisation
 Mesure sans consommation d’oxygène

CONTROS™ Mobile Leak Detection Systems

HydroC™ Mobile Early Leak Detection System is the combination of three different measuring instruments that allows for the trustable detection, identification and characterization of oil and gas related pollution in water and guarantees a low false alarm rate.

 

The MELDS consists of:

  • A polycyclic aromatic hydrocarbon (PAH) sensor based on the principle of fluorescence for the detection of any oil in water in real time,
  • A methane (CH4) sensor unambiguously detecting gaseous and dissolved CH4 as well as other hydrocarbons in water,
  • A conductivity, temperature and pressure (CTD) probe for the measurement and identification of anomalies in the environmental baseline.

CONTROS™ Permanent Leak Detection System

 

Globally, the integrity of subsea pipelines and production systems is becoming a major concern as authorities become less tolerant of pollutant spills into the marine environment. This is not only a responce to catastrophic events like the Macondo blow out in the Gulf of Mexico but also to the existence of numerous small hydrocarbon outflows at the seafloor like "leaky" abandoned wells. In this respect, the ability to detect and to monitor the distribution of subsea oil or gas leakages at a very early stage is of utmost importance to ensure compliance with legislative requirements and to safeguard a green and healthy planet.

The CONTROS monitoring concepts and systems address the site-specific needs and requirements of offshore oil & gas production, including manifolds, wellheads, templates, risers and pipelines. The backbone of these systems is the HydroC™ system, which was specifically developed to allow fast, real-time and in-situ detection of gaseous and dissolved hydrocarbons in the water column. The HydroC™ sensor system has been implemented into a variety of mobile deep sea platforms (e.g. AUV, ROV) and is succesfully operated in leak detection surveys and pipeline inspections. The newly developed and successfully tested permanent monitoring system is a step ahead in leakage monitoring in shelf areas.

In order to achieve the best, and individualized subsea monitoring solutions, CONTROS offers consulting and engineering services. Our versatile and easy to handle monitoring systems are able to incorporate any third party sensors such as CTD, pH, CO2, DO, icListen Hydrophones, active acoustics and cameras. Since 2012 the CONTROS systems have a proven track record in both scientific and industrial subsea monitoring applications.

HydroC™ PAH Subsea Fluorometer

Sonde HAP (hydrocarbures polycycliques aromatiques) HydroC™

La sonde Contros HydroC™ est un fluorimètre submersible unique pour des mesures in-situ et en ligne des hydrocarbures polycycliques aromatiques (HAP).

Comment fonctionne-t-elle?

Une source de lumière génère de courts flashs lumineux dans le milieu. Une partie de la lumière de fluorescence induite à l’intérieur du cône d’émission revient vers la sonde. Un filtre passe bande réduite la largeur du spectre de cette lumière de fluorescence en fonction des exigences de la surveillance recherchée. La lumière incidente est focalisée sur la photodiode silicium UV qui crée le signal électronique proportionnel, lui-même amplifié et converti en un signal exploitable.

 

HydroC™ Subsea Fluorometer for Polycyclic Aromatic Hydrocarbons (PAH)

is designed as compact and light underwater unit to detect PAH on the water surface as well as down to 500 meter or deeper water to  depth. The fluorometer allow continuous measurements and non-destructive sampling in combination with good specificity and low detection limits.

An excitation light source generates short flashes. A small part of the emitted fluorescence light coming from the illuminated cone. A band pass filter reduced the spectral range of the fluorescent light according to the special demands of the monitoring task. The incident light is focused onto the silicon UV photodiode which is measured electronically and converted into a voltage signal.
