Resumo: | |||||||||||||
The Direct Optical Wire Monitoring System, or simply MODA, is a system that Petrobras developed in partnership with the Fiber Optic Sensors Laboratory (LSFO). This system uses fiber-optic strain gauges widely used in Pre-Salt projects.
There is currently a need to develop the system for applications under temperatures higher than the temperature range for which the system is currently specified. This will require testing new adhesives that are specified at higher temperatures than the adhesives currently used. Therefore, the proposed Course Completion Work (TCC) consists of conducting experiments, such as tensile tests, and analysis of test data, involving new adhesives to bond the optical fiber containing the strain sensors based on Bragg Grid.
My activities will be to follow and participate in all phases, such as designing specimens, participating in the bonding of fiber optic sensors to the specimens using adhesives (sensor instrumentation), monitoring tensile tests, and analyzing and interpreting test results. The tests described in this work were performed at room temperature because they are preliminary tests that have been carried out to choose the adhesives that will be tested at higher temperatures. Therefore, these tests were used to identify the new adhesives to be tested at higher temperatures, and thus to verify if the adhesives will be useful for future applications of the MODA system or not.
The analysis and all conclusions from this TCC will be made using the tensile test data and analyzing the light spectra detected by the Fiber Bragg Grating (FBG) sensor, comparing mainly the peaks of the graphs involving wavelengths and power.
