About the Client

The GNL Mejillones Liquefied Natural Gas (LNG) Plant was established by GDF SUEZ and the Chilean State Copper Company CODELCO in Northern Chile in 2010. The plan is a 750-Million US Dollars investment to secure natural gas supply for the mining industry.

Project Objective

Post-earthquake assessment of the GNL Mejillones Liquefied Natural Gas (LNG) Plant upon the occurrence of an earthquake to ensure safe operations.

The same Aspen technology implemented in the USArray/TA project delivered 99.8% data return over ~1,800 installations in more than ten years of operation.

After ten years of successful operation in the continental USA, the current USArray/TA phase comprises of 280 stations operating in Alaska, in a harsh environment like never before, where will stay operational until 2021 when removal will begin. By the end of this U.S. National Science Foundation USArray/TA sponsored project, a large number of Aspen stations will be transferred to the Alaska Regional network, operated by the University of Alaska, Fairbanks.

Project Achievement

Implementation of the CONDOR Seismic Monitoring System solution, which collects data from two free-field seismic stations and determines, in real-time, whether the earthquake’s impacts on the plant have or have not exceeded its Operating Basis Earthquake (OBE) design requirements.

Project Insights


Implemented CONDOR system solution to monitor seismic activity in real-time with automatic OBE analysis, alarm and reporting.

Safe Operations

Increased Operators confidence on safe operations and emergency response procedures.

Operational Continuity

Avoided uncertainties in decision making process and continuing of operations.


Provided continued serviceability since start-up in 2010 and through major earthquakes that have struck Chile.
