Fiber Optical Gages,
a unique technology for specific applications

Fiber Optic Technology is suitable for severe applications
With over twenty years of existence in the industry, the technology of fiber optic strain gage based on Fiber Bragg Gratings (FBG) is now recognized. Operation is simple and the tools necessary for its operation are now available “off the shelf” (optical fusion/splicing “welding” machines, industrial connectors, interrogators). In addition, the number of Telecom specialized technicians knowing how to process optical gages is significantly growing. The advantages of the FBG gages are multiple, but the technology is still not sufficiently known. Continued efforts are needed to inform and train the industrial operators of FBG gages’ advantages:
– Total insensitivity to electromagnetic fields,
– Ease of use in hazardous areas (compliant with Class 1 Div 1),
– Long distance between sensor and measuring system (several miles)
– Possibility to install up to 20 FBG on the same single Telecom fiber,
– Long-term stability without any maintenance,
– High strain capability up to 10,000 microstrains,
– High fatigue strength up to 100 million of cycles
– Insensitive to moisture and corrosion
– Low cost due to High Volume Telecommunication Industry

All these criteria and benefits are promoting the use of FBG sensors (passive, without drift and without energy) in the medical, aerospace, railway, oil and gas, hydraulic and major infrastructure sectors.

The optical gage: the right solution

In many case studies based on Cementys’ experience, fiber optical gages expand the existing field of use of conventional resistive strain gages for:
– Measures in strong electromagnetic fields (railway, rotating machine, lightning hazard, particle accelerators)
– Class 1 Div1 measurements (LNG tanks, offshore platforms, turbo-generators)
– Passive measurements in humid environments (instrumentation for Topside and Subsea Infrastructures)
– Hydro-geological measurements
– Blood pressure measurements, etc.
Thanks to those advantages, fiber optical gages are now considered as an alternative or a complementary solution to the resistive strain gages. An upfront analysis of the environment and the scope of measurement is necessary to find the best technical and financial solutions between optical and resistive gages.
We must change old habits and rethink the use of strain gages considering the Fiber Bragg Grating solutions.

SensoLuxCRYO©: 
A cryogenic cable for LNG applications

Cementys is proud to present its latest optical fiber cable, specifically designed for cryogenic environments.
SensoLuxCRYO© is perfectly suited for both local and distributed measurements in extremely cold environments such as LNG tanks, cryogenic pipelines or ethane and methane carriers.
The SensoLuxCRYO©with an external diameter of 2.4 mm, can include up to 4 fibers in a loose tube configuration, either in a “Single Mode” for local measurements using Bragg Gratings or in a “Multi Mode” for Distributed Temperature Monitoring allowing leak detection and thermal mapping.
This cable has been fully tested and qualified, and is now installed on several projects in India, France, Poland and USA.

CAREM25: Cementys signs a new contract for Nuclear Asset Integrity Monitoring in Argentina

Cementys team is
proud to collaborate on the instrumentation project of CAREM25 experimental reactor, designed and built by the CNEA (Comisión Nacional de Energía Atómica) in Argentina. Following a Cementys workshop on Asset Integrity Monitoring of nuclear facilities, the CNEA has awarded Cementys with the supply and installation contract of sensors and data acquisition systems on the confinement building of the experimental nuclear reactor CAREM 25 (SMR prototype 25MW). The construction of this reactor is ongoing and will be completed by 2020. Cementys continues its expansion on the monitoring market of concrete nuclear reactors worldwide (Russian VVER1200, French EPR1650, Korean APR1400).

Optical Fiber Sensing for Asset Integrity Monitoring in Houston, TX

Cementys is co-organizing with the University of Houston-Downtown, a professional training on Optical Fiber Sensing for Asset Integrity Monitoring. Like more than 25 engineers last year, come and learn about fiber optic sensing on november 3-4, 2016!This professional training workshop will take place at the UHD, Willow Street Pump Station, and is dedicated to engineers, inspectors, and facility managers from construction companies (EPC), infrastructure operators (petrochemical, onshore & offshore, pipeline assets), power and utility network owners concerned with Asset Integrity Monitoring.
Real-Time Optical Fiber Sensor Demos and Case Studies will be presented.

New Asset Integrity Monitoring contract in India

Cementys team is proud to collaborate with Reliance Industries Limited (RIL) on the monitoring project of two liquid ethane pipelines being built in Dahej, India. To monitor the temperature of two 6 miles long pipelines during the commissioning and operation phases, Cementys provides its cryogenic optical cable solution SensoLuxCRYO©and its industrial interrogator SensoLoggerT©, that can be interfaced with any type of SCADA (Supervisory Control And Data Acquisition). With the DTS Cementys technology, distributed temperature measurement is integrated directly within industrial processes of the petrochemical plant (first cool-down monitoring and leak detection).

Analysis and vibration diagnosis

Cementys strengthens its diagnostic division with the VIBRA equipment from Profound. It allows:
– The vibration control due to vehicle passages (train, tram, truck, etc.),
– Monitoring of the effects of natural or induced phenomena on structures,
– The vibration control and monitoring on quarries, mines or industrial power plant compared to standards. These tests can also help to determine the site propagation law (Chapot’s law),
– Determine the vibration’s impacts on structures and people according to ISO standards related to the mechanical vibrations in the environments,
– The monitoring and diagnosis of faults on machines and their housing,
– The vibration monitoring and diagnostic on singular structures (windfarm, pylon, chimneys, etc.).

OTC 2016
Booth 4049E

The Offshore Technology Conference(OTC) in Houston is one of the most important global Oil&Gas events today. It brings together more than 100.000 industry leaders from more than 110 countries. They all want to share and improve technical and scientific knowledge involving offshore resources and environmental issues.
OTC is the ideal location for us to present our latest innovations and applications in the Oil and Gas industry. Vincent Lamour (Chief Technology Officer) and Pierre de Lacaze (Instrumentation Engineer) will be there to welcome you, answer all your questions and show our monitoring demonstrators on Optical Fiber Stress Measurement and Pipeline Leak detection.
