“…Key information such as damaged or debonded coatings can be extracted by further analyzing the complex wave physics involved in multi-layer, concentric pipe structures. [110][111][112][113][114][115] The geometry of the pipe can also limit the range of GWT. Sharp bends in the pipeline can severely distort signals; the selected mode can be converted to other propagation modes due to the change in geometry.…”

One of the largest movers of the world economy is the oil and gas industry. The industry generates billions of barrels of oil to match more than half the world’s energy demands. Production of energy products at such a massive scale is supported by the equally massive oil and gas infrastructure sprawling around the globe. Especially characteristic of the industry are vast networks of pipelines that traverse tens of thousands of miles of land and sea to carry oil and gas from the deepest parts of the earth to faraway destinations. With such lengths come increased chances for damage, which can have disastrous consequences owing to the hazardous substances typically carried by pipelines. Subsea pipelines in particular face increased risk due to the typically harsher environments, the difficulty of accessing deepwater pipelines, and the possibility of sea currents spreading leaked oil across a wide area. The opportunity for research and engineering to overcome the challenge of subsea inspection and monitoring is tremendous and the progress in this area is continuously generating exciting new developments that may have far reaching benefits far outside of subsea pipeline inspection and monitoring. Thus, this review covers the most often used subsea inspection and monitoring technologies as well as their most recent developments and future trends.

“…Both classical and modern instruments are used for flood monitoring. Easily detects the leakage and defect Still in research process to apply for BCPs [32] Radiography Easily distinguishes deep layers of BCPs Can be the cause of damage for humans and sea animals [33] Fiber optics Precise results with less loss of data Installation is tedious, and permanent installation is required for it [34] From Table 8, it is observed that the output readings from classical instruments like acoustic emissions can be interrupted on irregular surface applications. Ground penetrating radar (GPR) and electrical field signature can provide moderate results with their continuous attachment to the observation units.…”

“…Further, external surface load such as traffic, heavy equipment, and superstructure built on the BCPs also impact its integrity [16][17][18][19][20][21][22][23][24][25]. Likewise, flood [26][27][28][29][30][31][32][33][34], blasting [35][36][37] and earthquakes [38][39][40][41][42][43][44] also affect the safe operations of BCPs.…”

Threat to the sustainability of buried continuous pipelines (BCPs) can be associated with different factors such as corrosion, natural hazards, and third-party influences. In the past, these factors have been discussed independently by various researchers. Despite these studies, there is still space for a comprehensive review report to be performed in this domain. The purpose of this article is to manage, classify, and describe the literature work done in this sphere. Firstly, the screening of various factors based on their damage criteria has been carried out. An environmental analysis is performed to review the impact of different parameters that can influence the sustainability of BCPs. Further, a technical review on primary factors has been done to examine and measure the causes, damages, mitigation, and inspection techniques. In the last stage, review based decision has been performed. Results of the current study shows that research contribution for corrosion and earthquake factors are in an advanced stage, followed by flood and external surface loads, that are still in progress. However, temperature variations and blast factors are in a premature phase and need broad inspection and research support.

“…As started above, casing eccentricity is more common in horizontal wells due to the gravity effect. However, even with the existence of centralizers on the casing, this eccentricity in vertical wells can still appear [54].…”

“…They focused on the interpretation of a sonic response in a well cased with double steel strings cement to rock formation for evaluating the integrity of the cement. Machine learning algorithms were employed on experimental datasets to develop diagnostic techniques for the cement condition Liu and Choi [54] analyzed, from experiments and analytical models, several excited guided wave modes that propagate in complex structures involving two casing and eccentricity. It presented four degrees of freedom that control the eccentricity of the double strings and analyzed the influence of inner casing eccentricity in slowness curves.…”
