Evaluation of the performance aging structures is essential in oil and gas industry, where inaccurate prediction structural can have significantly hazardous consequences. The effects structure failure due to significant reduction wall thickness, which determines burst strength, make it very complicated for pipeline operators maintain serviceability. In other words, serviceability pipelines elbows needs be predicted assessed ensure that or collapse strength capacities remain less than maximum...
This study proposes a method for assessing the risk of ship hull collapse following collision. A probabilistic approach is applied to establish relationship between exceedance probability collision and residual ultimate longitudinal strength index. set credible scenarios which represent entire range possible accidents selected using sampling technique based on density distributions influencing parameters. The amount location damage individual are characterised LS-DYNA nonlinear finite...
Hydrogen is widely regarded as a key element of prospective energy solutions for alleviating environmental emission problems. However, hydrogen classified high-risk gas because its wide explosive range, high overpressure, low ignition energy, and fast flame propagation speed compared with those hydrocarbon-based gases. In addition, deflagration can develop into detonation in ventilation or explosion guide tunnels if overpressure occurs, leading to the all combustible quantitative evidence an...
This paper presents an innovative method using Latent Diffusion Models (LDMs) to generate temperature fields from phase indicator maps. By leveraging the BubbleML dataset numerical simulations, LDM translates field data into corresponding distributions through a two-stage training process involving vector-quantized variational autoencoder (VQVAE) and denoising autoencoder. The resulting model effectively reconstructs complex at interfaces. Spectral analysis indicates high degree of agreement...
In this paper, different evaluation methods of Hot Spot Stresses (HSS) have been applied to four welded structure details in order compare them and illustrate their differences. The HSSs at failure-critical locations were calculated by means a series finite element analyses. There was good overall agreement between experimentally determined HSS on the critical locations. While procedures exist for computation structural hot-spot stress joints, recommendations within International Institute...
Elbows are a vulnerable part of piping systems in erosive environments. Traditionally, plugged tees used instead elbows when the erosion rate is high. However, advantage over large-scale pipelines unclear. A comprehensive computational fluid dynamics study was carried out to predict and elbows. numerical method first for aluminium with available experimental data through which accuracy solution verified. After validating model, modelling compare rates varying geometrical conditions, ranging...
Numerous oil tanker losses have been reported and one of the possible causes such casualties is caused by structural failure aging ship hulls in rough weather. In ships, corrosion fatigue cracks are two most important factors affecting safety integrity. This research about effect on hull girder ultimate strength behavior double according to after Part I: stiffened panel. Based data I (time-dependent wastage model CSR model), when progressing fourtypes tankers (VLCC, Suezmax, Aframax,...
Age-related problems especially corrosion and fatigue are normally suffered by weatherworn ships aging offshore structures. The effect of is one the important factors in Common Structural Rule (CSR) guideline ship design based on a 20 or 25 years life. aim this research clarification ultimate strength stiffened panels various types double hull oil tankers. In case ships, phenomenon caused ambient environment it has different characteristics depending parts involved. Extensive considering...
