“…Figure. 12 shows that the vertical configuration caused the height magnitude of induced voltage for the first 40m separation distance between the centre of power line and the pipeline than any other configuration [11]. This is due to the high density of the resultant electromagnetic field EMF produced from the vertical power line than the others and still has the higher magnitude than the delta configuration until reaches 80m.…”

This paper investigates the interference between electromagnetic field produced by high voltage power lines and liv ing organisms and metallic objects underneath the transmission lines such as ships, at rivers crossing, and vessels passing under or near to power lines. Metallic pipelines buried in the same corridor are affected with many factors, na mely : the power line configuration, separation distance between transmission line and pipeline, separation distance between conductors, the transmission line tower height, existence of the earth wire, the sequence of the power supply, the length of corridor and the fault conditions. The equations of magnetic fields of the transmission lines and the density of currents induced in the human bodies and metallic ships surface were introduced. The induced voltage on the neighbouring pipelines was calculated. A computer program was developed to model and simu late the magnetic fields produced by power lines. The program calculates the current density induced in objects underneath or in the neighbourhood of the transmission line. The results obtained using the developed program illustrated to be consistent with previous literature results. The obtained results showed to be satisfactory and consistent with the experimental ones.

Limited studies have been conducted on the effect of a magnetic field on the corrosion behavior of steels. Investigating the effect on pipeline material in the oil and gas industries will be beneficial regarding corrosion prediction and control. In this work, the effect of a magnetic field on the corrosion process of API 5L X65 carbon steel was investigated in a well-developed flow loop using potentiodynamic polarization curves and electrochemical impedance spectroscopy (EIS). Using permanent magnets and a well-designed corrosion electrode set-up, the corrosion mechanism of API 5L X65 steel was studied at different magnetic orientations and different flow conditions in a NaCl solution. The surface morphology of the corroded samples was studied using a scanning electron microscope, and the micro-morphologies of the corrosion deposits and the surface elemental composition were analyzed. The results show that the presence of a magnetic field increases the corrosion rate of API 5L X65 carbon steel, and that flow velocities and magnetic orientation have a significant influence on the anodic corrosion current. The results of the polarization curves indicate a negative shift in the Tafel curve, leading to an increase in the corrosion rate with the introduction of a magnetic field in the flow system. The results of the EIS show that the charge transfer rate is decreased when a magnetic field is applied. This work provides important direction in terms of the understanding of the combined effect of magnetism and flow on the corrosion in pipelines used in the oil and gas industries.
