This paper presents a probabilistic method to predict fatigue crack growth for surface flaws in pipelines using a particle filtering method based on Bayes theorem. The random response of the fatigue behavior is updated continuously as measured data are accumulated by the particle filtering method. Fatigue crack growth is then predicted through an iterative process in which particles with a high probability are reproduced more during the update process, and particles with a lower probability are removed through a resampling procedure. The effectiveness of the particle filtering method was confirmed by controlling the depth and length direction of the cracks in the pipeline and predicting crack growth in one- and two-dimensional cases. In addition, the fatigue crack growth and remaining service life with a 90% confidence interval were predicted based on the findings of previous studies, and the relationship between the fatigue crack growth rate and the crack size was explained through the Paris’ law, which represents fatigue crack growth. Finally, the applicability of the particle filtering method under different diameters, aspect ratios, and materials was investigated by considering the negative correlation between the Paris’ law parameters.

“…Among the literature in regard to the surface crack growth in pipes, experimental studies [12,[20][21][22][23][24][25][26], as an indispensable and important component, have been conducted on surface cracked pipes for the purpose of understanding the mechanism of surface crack growth, calibrating and validating related numerical and analytical evaluation methods. The majority of the studies focused on numerical approaches, mostly by means of the FE method [12,[27][28][29][30][31][32][33][34][35][36][37][38].…”

The surface crack, also known as the partly through-thickness crack, is a serious threat to the structural integrity of offshore metallic pipes. In this paper, we review the research progress in regard to surface crack growth in metallic pipes subjected to cyclic loads from the fracture mechanics perspective. The purpose is to provide state-of-the-art investigations, as well as indicate the remaining challenges. First, the available studies on surface cracked metallic pipes are overviewed from experimental, numerical, and analytical perspectives, respectively. Then, we analyse state-of-the-art research and discuss the insufficiencies of the available literature from different perspectives, such as surface cracks and pipe configurations, environmental influential parameters, the girth welding effect, and numerical and analytical evaluation methods. Building on these surveys and discussions, we identify various remaining challenges and possible further research topics that are anticipated to be of significant value both for academics and practitioners.

“…The other is the PWT location, which is important for the detection and maintenance of in-service pipes, especially long-distance pipes. Recently, many researchers have focused on developing nondestructive testing (NDT) techniques for detecting PWT defects, including infrared thermography, 3) X-ray, 6) electrical potential drop, 7) ultrasonic, 8,9) magnetic flux leakage, 10) eddy current method, 11) elasticplastic finite element analysis 12) and so on. However, they can only inspect a pipe locally except for the hollow cylindrical guided wave (HCGW) of ultrasonic method.…”

This research aims to find an efficient and nondestructive way of detecting the locations of the pipe wall thinning (PWT) in a long-distance metal pipe at open-end condition. Time domain measurement of microwave signals is adopted in the method since microwaves can propagate a long distance with low attenuation in the pipe and reflection occurs at the PWT section. To carry out the measurement, a vector network analyzer and a self-designed coaxial-line sensor were used to generate microwave signals propagating in the pipe. By analyzing the time domain response of the signals and extracting the time of flight (TOF) that corresponds to the PWT location, the locations are quantitatively evaluated after the group velocity of the signals propagating in the pipe was calibrated. In order to approach a pipe with different PWT degrees and locations, three brass pipes with an inner diameter of 17.0 mm and lengths of 453 mm, 455 mm, and 2000 mm, respectively, were used in the experiment. In addition, five joints, which have the length of 17.0 mm and inner diameters from 17.10 to 18.20 mm were also used. The arithmetical mean error of the evaluation for PWT locations is found to be less than 1.7 mm, i.e. less than 0.068% of the length of the corresponding pipe. It indicates that a quite efficient and precise method to remotely and quantitatively evaluate PWT locations in a long-distance pipe has been established.
