Subsea Gas Pipeline Risk Assessment During Hot Tapping Installation

Risk Assessment System of Spatial City Gas Pipeline

In order to improve the administrative level of pipeline safety among the surrounding environment, this paper proposes a pipeline risk assessment system of space and visualization based on the current situation of the gas pipeline risk assessment. The database of pipeline surrounding natural environment and social environment are established by using GIS. And the scatter grams on the accident s...

risk assessment and management of gas transmission lines, in alamout natural gas pipeline

using natural gas as a clean, plentiful and inexpensive source of energy in recent years has progressively increased in iran. pipelines are the most common system to transport natural gas from field to different regions of iran. these pipelines always pose risks to surrounding population and environments. the aim of this study was to assess the potential health, safety, and environment risk of ...

Modal Reduction Based Tracking Control for Installation of Subsea Equipments

This paper proposes a control strategy for the deep sea installation of wellhead equipments hanged by flow line structures, named risers. A fundamental step of this operation is the positioning of the equipment over the wellhead, which can be costly, time-consuming, and unfeasible in bad weather conditions. The approach taken considers the riser structure an Euler-Bernoulli beam submerged in a ...
