Development of Subsea Pipeline Buckling, Corrosion and Leakage Monitoring

A Leakage Monitoring System of Pipeline in Heating Network

Supervisory control and data acquisition system (SCADA) is used to monitor the operating data of heating network. But it can do data acquisition and some simple operations only. So in this paper with the data collected by SCADA a leakage monitoring system of pipeline in heating network is designed by the Matble graphical user interface program (GUI). The theoretical basis of this monitoring is ...

Scour Monitoring System for Subsea Pipeline Based on Active Thermometry: Numerical and Experimental Studies

A scour monitoring system for subsea pipeline based on active thermometry is proposed in this paper. The temperature reading of the proposed system is based on a distributed Brillouin optical fiber sensing technique. A thermal cable acts as the main component of the system, which consists of a heating belt, armored optical fibers and heat-shrinkable tubes which run parallel to the pipeline. Th...

subsea corrosion management: challenges and limitations

subsea structures such as manifolds, line pipes and flow lines are important investments. also because of the sensitivity of environmental issues, corrosion of these structures is of vital importance. subsea corrosion management is different from on-shore and shallow water off-shore corrosion management in mainly three factors: materials, corrosion management practice and cathodic protection. t...

Improved FTA Methodology and Application to Subsea Pipeline Reliability Design

An innovative logic tree, Failure Expansion Tree (FET), is proposed in this paper, which improves on traditional Fault Tree Analysis (FTA). It describes a different thinking approach for risk factor identification and reliability risk assessment. By providing a more comprehensive and objective methodology, the rather subjective nature of FTA node discovery is significantly reduced and the resul...
