Description
This study provides comprehensive documentation and detailed information on Funvisis' extensive experience in managing AS117 and AS118 for over two decades, as part of Venezuela's commitment to the Comprehensive Nuclear-Test-Ban Treaty Organization (CTBTO). This article presents a robust methodology based on thorough records of both preventive and corrective maintenance carried out at these remote locations, as well as on evaluations conducted on-site and at the Funvisis analysis centre where the NDC operates. The recent joint maintenance effort at AS118 is the epitome of best practice. It involved experts from both the CTBTO and Venezuela and addressed issues related to expected degradation associated with the lifetime of measurement, communication, power and other parts and components. It also addressed related considerations for reassessing station locations, taking into account changing factors such as environmental noise, anthropogenic, security (including vandalism) and other varying energy requirements. Consolidating these experiences into a single paper provides invaluable information on how to effectively manage the stations. These results are of benefit to NDCs and all States Signatories in general, promoting a collaborative approach to seismological monitoring and improving the harsh conditions under which our secondary stations must continue to operate.
