A highly transient flow regime called riser slugging can develop in pipelines from wellheads to separation tanks which introduces severe oscillations of pressure and flow rates in off-shore processes. Mitigation of the intensity of riser slugging may be achieved via anticipative control actions on valves positioned at the entrance and at gas/oil exits of the separators. In Phase 1, this work is...

Environmental assessments are essential in order to align the process of country's progress towards sustainable development. It is important for the project to be implemented in direction of sustainable development, which is to carry out a project in such a way that in both short and long term, the greatest advantages and the least harm are inflicted on the environment, economy, communities, an...

I n this paper, we present a robot system for inpipe inspection of underground urban gas pipelines. The robot is configured as an articulated structure like a snake with a tether cable. Two active driving vehicles are located in front and rear of the system, and passive modules such as a control module are chained between the active vehicles. The proposed robot has outstanding mobility oflered ...

This paper examines the spatial and temporal distribution of failures in three critical infrastructure systems in the United States: the electrical power grid, hazardous liquids (including oil) pipelines, and natural gas pipelines. The analyses are carried out at the state level, though the analytical frameworks are applicable to other geographic areas and infrastructure types. The paper also d...
