Fibre Optic Monitoring (FOM) - In-Situ Test

E-mail Print

Currently, fibre optic sensors are under in-situ investigation by DBE TECHNOLOGY in a sedimentary environment (Konrad mine) and in a salt environment (Morsleben) in Germany. Here at the GTS, fibre optic sensors have been installed in the sand/bentonite buffer and backfill of the Gas Migration Test (GMT). Two humidity sensors and one total pressure cell are installed in the sand/bentonite buffer (Layer12). Two temperature sensors, a humidity sensor and temperature sensor are installed in the backfill (Layer13 : sand layer).

25 Years experience
2009 marked a significant milestone in the history of the Grismel Test Site with the running of experiments which have spanned more than 25 years. Read more about the 25 years of scientific exploration in the 25 Years of History at the Gimsel Test Site section. Full details of our 25 year celebration events will be posted shortly


The GTS underground facilities are also available to interested 3rd parties for underground testing and research. The GTS offers cost-effective access to a fully developed, well characterised underground research facility with round the year logistical support - please contact Dr. Ingo Blechschmidt, Head of the Grimsel Test Site, for further details.
