Abstract:

In the past few decades, there have been many numerical studies on the scour around offshore pipelines, most of which concern two-dimensional setups, with the pipeline infinitely long and the flow perpendicular to the pipeline. Based on the Ansys FLUENT flow solver, this study establishes a numerical tool to study the three-dimensional scour around pipelines of finite lengths. The user-defined functions are written to calculate the sediment transport rate, update the bed elevation, and adapt the computational mesh to the new boundary. The correctness of the model has been verified against the

Abstract:

Onshore oil and gas pipelines are often buried beneath the river bed and channel banks. One of the primary reasons for the exposure of buried pipelines is the scouring mechanism that occurs when shear stress induced on riverbed by flowing water exceeds the resistance of channel bed material. Depending on the free spanning length and watercourse flow velocity, the vortex shedding phenomena may cause interactions resulting in a catastrophic pipeline failure. Accurate estimation of parameters that influence critical span length and scour depth become extremely important to maintain the integrity

Abstract:

Corrosion poses a significant risk to the safety of energy pipelines, while landslide disasters emerge as the primary threat responsible for triggering pipeline failures across mountainous areas. To date, there is limited research focused on the safety of energy pipelines considering the synergistic effect of corrosion and landslides. The present study proposes a finite element (FE)-based model to assess the condition of corroded pipelines under landslides. The effects of corrosion dimensions (length and depth) and location are determined. A novel equation is finally developed to predict the m

The paper considers the dynamic stability of submerged pipelines with denudation and sagging depending on their stiffness and the river flow rate. The hydrodynamic force frequency and natural vibrations of the pipeline are calculated at the actual and critical length of the pipeline sagging. It is shown that the frequency of the external hydrodynamic force applied to the sagged pipeline with the length corresponding to the critical, coincides with the frequency of natural vibrations. It is found that the loss of stability of submerged pipelines occurs in the resonant region of the pipeline vib

Abstract:

For the aviation bending pipe, the fluid-structure interaction 14-equation model is established, and the Laplace transform is used to solve the problem in the frequency domain. For the pipeline with a single elbow, the influence of bending parameters on the frequency response of the pipeline in the frequency domain is analyzed by using the 14-equation. At the same time, for pipelines containing two elbows, we analyze the influence of bending parameters on the natural frequency of the pipeline in different spans. In the end, the accuracy of the simulation is verified by the modal knocking test.

Experiments covering a wide range of incoming flow velocity, pipe diameter and plate length show that there exists a critical pressure difference over which the movement of sediment and, thus, scour takes place.

Abstract:

This is a new revision of the Year 2 work. The NDE-3-2 project seeks to advance the state of the art for integrity assessment of difficult to inspect pipelines by proposing guidance for application of alternate inspection approaches other than hydrostatic test, in-line inspection and ECDA/ICDA currently prescribed by Code and Regulations. The hydrostatic test and in-line inspection methods for integrity assessment have in common the concept that the full length of the pipeline is assessed. Many pipelines exhibit configuration and operational issues that preclude integrity assessment by the pre

Abstract:

This zipped package includes a number of newly added features to the OBS software relevant to the dynamic simulation of pipelines. The additions include a function to extract on-bottom wave induced velocities hydrodynamic forces on a given length of pipeline with arbitrary distribution of the nodes; a new dynamic simulation module to perform dynamic simulations for a single pipe element; two new soil models including the Verley and Sotberg for sand as well as a custom soil model as per the approach recommended in DNVRP- F114. The added soil models are implemented in the dynamic solver, which p

Abstract:

In an effort to progress the development of hydrocarbon fields found in water depths beyond 1000 feet, the oil and gas industry is considering cost effective methods of subsea pipeline installation. As an established and reliable oil and gas transportation system, the pipeline will be an important factor in deepwater development. Surface installation methods are expected to become costly in deepwater due to the necessary equipment modifications and vessel requirements which are synonymous with increased tension capability and deepwater station keeping ability. This estimated increase in instal

Full text

Abstract:

There was a need to define the spatial density of stress-corrosion crack arrays that develop in operating gas-transmission pipelines and in laboratory test specimens of line-pipe steel, to improve understanding of the factors that control the density and provide data to test models of pipeline cracking. Within the broad definition of crack density are included the locations, numbers, lengths, depths, and degree of linkage of cracks. An analysis has been conducted of location, numbers, lengths, depths, and degree of linkage of stress-corrosion crack colonies in samples from the field and from l

Abstract:

This study collected and analyzed more field data to enhance the probabilistic model for predicting internal corrosion threats in nominally dry natural gas pipelines developed previously, especially in the region where the internal corrosion risk is higher. The Excel� tool developed previously was also updated with the enhanced model for predicting internal corrosion risk based on basic operating conditions, (i.e., average gas operating temperature, seasonal gas operating temperature amplitude, and operating pressure). In this project, a general-purpose Excel tool was created to allow calculat
