Catastrophic Risks Analysis For Telecommunication System In Petro Energy Company - Sudan

Abstract

In industries like oil and gas, Telecommunication Networks used multiple communication technologies to eliminate any possibilities of failures, when the network is operational, in case of catastrophic situation these networks have strict and tight requirements for robust. Accordingly availability of the transmission network is essential, even short interruptions especially during catastrophic risks may cause considerable economic losses and major environmental impacts. In reality the network can face multiple of problems, which can halt or interrupt communication for seconds, minutes, hours and in some cases days. In this thesis, the robustness of transmission networks for oil and gas facilities is evaluated for normal and catastrophic risk situations to avoid maximum interruptions in communication by comparing the major three technologies (Optical, Microwave LOS, and Satellite VSAT) in terms of availability, repair and replacement time and costs, applying Failure Modes and Effect Analysis (FMEA) to consider any future technological requirements during risk situation. The results of the analysis show that the oil fields transmission technologies have some predetermined trends, impacts and risks associated with different kind of manmade and natural hazards at different geographic locations, which can be prevented by applying Failure Modes and Effect Analysis (FMEA) with a combination of transmission technologies for both normal as well as catastrophic situations. This thesis highlights the importance of robustness related to repair and replacement time and costs due to catastrophic calamities and will serve the oil industry to make an efficient decision while designing or extending transmission networks for Oil and Gas facilities.
