“…В этом случае ситуация разрушения особенно критична, поскольку может вызвать техногенную катастрофу. Для увеличения срока пригодности поврежденных участков магистральных газопроводов в местах дислокации дефектов используют бандажирование композитными накладками -бандажами В РАЗРАБОТКА [3].

The operation of sections of main gas pipelines that are on the verge of developing a design resource is associated with a number of problems in ensuring industrial safety. One of the most acute problems is the occurrence of local defects. The main material for the manufacture of main gas pipelines is steel. During the operation of the pipeline, local defects occur due to metal corrosion or mechanical damage to the gas pipe. Such concentrators with high internal pressure in the gas pipeline can lead to the destruction of the entire structure. In this case, the situation of destruction is especially critical, since it can cause a man-made disaster. To increase the shelf life of damaged sections of main pipelines in places where defects are located, banding with composite linings is used. The article contains part of a comprehensive study, which consisted in the development of methods for modeling the main gas pipeline for oil and petroleum products under seismic loads, dynamic stress-strain state under the influence of seismic loads and stress-strain state of a damaged gas pipeline reinforced with composite linings under the action of internal pressure. The technology of manufacturing linings from composite material is also described in detail. At the same time, a geometric model of the section of the main gas pipeline with composite linings was developed and an analysis of the loading of the section of the main gas pipeline in ANSYS was carried out, provided that the lining is mounted without tension on the pipeline and provided that the lining is mounted with tension, where a comparative analysis showed that the installation condition of composite linings does not significantly affect the static stress state.

Fiber-reinforced polymer (FRP) materials are used to reinforce and repair subsea pipelines in the oil and gas (O&G) industry due to their great strength-to-weight ratio as well as corrosion resistance. The extreme environmental conditions that subsea pipelines must endure include high pressure, high temperature, as well as corrosion. Modelling the effects of these conditions on the repaired pipeline can be challenging, and inaccuracies in modelling the underwater environment can lead to incorrect predictions regarding the repaired pipeline's behaviour. The finite element method (FEM)’s capabilities, as well as applications, are examined in this work. FEM is being used in place of time-consuming processes and conventional codes since they have demonstrated their strength as prediction tools. This article provides information on the to better understand the accuracy and reliability of the FEA modelling techniques used to simulate the behaviour of the FRP repair system under different operating conditions. The descriptions focus on the many types of composite fibres and the qualities that come from their components. Related document gathering was conducted from 2018-2022 and research on 53 papers were downloaded and acquired from the Scopus and Science Direct database. The review also discusses the insight into the practical implementation of finite element analysis (FEA) modelling involves understanding how FEA is used to solve real-world problems. Moreover, the findings show that by diversifying the FRP materials used in the repair design, the overall performance of the repaired pipeline can be optimized, leading to increased safety and reliability in subsea O&G operations. Also, the scope for future studies.

“…Conventional reinforcement methods for tubular joints typically involve welding metal stiffeners, such as collar plates [6][7][8][9], double plates [10,11], or external rings [12]. Additionally, the use of fiber-reinforced polymer (FRP) has emerged as an excellent alternative for combating environmental corrosion and improving structural performance in terms of joint strength and stress distribution [13][14][15][16][17][18][19]. Current design guidelines, including GB-50017 [20], CIDECT [21], and EC3 [22], incorporate numerous provisions for the reinforcement of joints, reflecting the advances and industry acceptance of these technologies.…”

A finite element (FE) analysis of corroded circular hollow section T-joints repaired using grouted clamps is presented in this study. To ensure an accurate simulation, experiments on a T-joint with uniform corrosion and an intact T-joint with grouted clamp are reproduced separately using an FE model. The experimental and FE modeling results correlate closely, displaying similar failure behaviors and load–displacement responses. Subsequently, a total of 56 FE T-joint models with varying degrees of corrosion on the chord, repaired by grouted clamp, were then analyzed numerically. The corrosion was artificially applied to the chord’s outer surface at depths of 10%, 20%, and 30% of the chord’s thickness. The models also account for variations in joint geometry, dictated by parameters β and γ, which range from 0.565 to 0.678 and from 21 to 28, respectively. Furthermore, grouted clamp’s properties were examined, including sleeve length, thickness, strength, as well as the thickness and strength of the grout, in relation to the complexity of the repair. The grouted clamp demonstrated significant repair capability, increasing the ultimate strength of the corroded joint by up to 2.23 times. Reinforcements that are both thicker and longer substantially enhance the joint’s ultimate strength. However, inappropriate repair construction results in an abrupt termination of the load–displacement curve and a brittle failure phenomenon outside reinforced chord region. Additional weight from the grouted clamp requires reasonable control, and sleeve overlapping ratio should be guaranteed to be greater than 0.7. The joint bearing capacity can be efficiently increased by thicker grouts and sleeves only in ductile failure cases. The confinement effect and mechanism of the grouted clamp in joint deformation were visually analyzed as stress distribution from FE analysis results. Finally, a prediction equation is proposed to estimate the static strength of the repaired joint through regression analysis.
