Real-time remote monitoring and risk management of oil & gas facilities subjected to natural hazards
Real-time remote monitoring and risk management of oil & gas facilities subjected to natural hazards
The term “natural hazard” is used to describe any natural pheno menon that might have a negative effect on humans and/or the environment. The natural hazards can be classified into two broad categorie s: geological and meteorological (e.g. landslides, volcanic eruptions, heavy storms, floods, droughts and high ambient temperatures). Furthermore, it...
