It is nowadays becoming increasingly common for new onshore structures and electrification systems to be installed in close vicinity to existing underground pipelines already equipped with their own CP and earthing systems. The problem with sharing common right of way between different structures is that their different earthing and CP systems are likely to interfere with each other. The coupling may reduce the performance of the individual designs or lead to major problems such as stray currents or shielding effects. Numerical modelling of these types of scenarios allows identifying such problems in advance, gaining understanding on the nature of the interference, and evaluating possible mitigation strategies. In this work the impact of constructing a solar power station across a set of transmission pipelines is investigated. The pipelines are protected by an ICCP system. The solar array includes galvanized piles and copper earthing system. The territory is mainly composed of clays or muds with flat and slightly undulating shapes with average resistivities in the order of 900 O-cm. Simulation results are presented showing the status of the pipelines before and after the solar array is constructed, as well as the solar array considering that the pipeline does not exist. The results show that the solar array piles and earthing system have measurable effects on the CP potentials on the pipeline.

Numerical Simulation of Punching Shear Capacity of GFRP Bar Reinforced Concrete Slabs-on-Ground Designed for Shrinkage and Crack Width Control

Product Number: MECC23-20047-SG

Author: Muhammad K. Rahman; Mesfer M. Al-Zahrani; Mohammed Fasil; Sami Al-Abdul Jabbar

Publication Date: 2023

Ground-supported structures such as slabs-on-ground, walkways, concrete pavements, storm-water channels, pipe supports, and industrial floors are exposed to harsh environmental conditions in the Middle East region, characterized by large temperature and humidity fluctuations. The highly varying temperature and humidity regimes accelerates moisture diffusion and the associated drying shrinkage in concrete slabs. The external restraint on these slabs by the subgrade and the internal restraint from the embedded reinforcement causes cracks on the surface of these slabs.

Study on the Mechanism and Influencing Factors of High Voltage Direct Current Interference

Product Number: 51317--9293-SG

ISBN: 9293 2017 CP

Author: Zitao Jiang

Publication Date: 2017

$20.00

High voltage direct current (HVDC) transmission results in a large direct current will into the earth. This may cause interference on a buried pipeline even though it is far from the earth electrode. In this work, numerical simulation was used to study the mechanism and influencing factors of HVDC interference.

The progress of science and technology, and the large-scale construction of infrastructures, not only bring about challenges to cathodic protection (CP), but also provide new opportunities for CP technologies. Challenges and opportunities promote the development of the CP technologies. In recent years, CP technology has achieved great development particularly in the following four aspects: first, numerical simulation calculation technology of cathodic protection, which has made remarkable achievements in theoretical research and practical application; second, data remote monitoring technology of cathodic protection, which has improved the management level of cathodic protection system by combining wireless transmission system and GPRS network; third, great progress has been made in the aspects of AC and DC stray current corrosion mechanism, evaluation method and elimination technology; fourth, the development of photocathodic protection technology.
