Introduction When it comes to a fast, non-intrusive, complete and meaningful inspection of an offshore pipeline in-line inspection (ILI) has been the method of choice for several decades now. However, not all pipelines, piping or other tubular structures can be inspected with in-line inspection tools (pigs). The method is usually limited to looping flow lines or export pipelines, specifically d...

The design of electrical wiring and hydraulic/pneumatic piping routes in aircraft is a long and repetitive process which is largely done by hand. Presented in this paper is progress in the development of a knowledge based routing system which automates much of the routing process using intelligent algorithms and interchangeable design rules. The system reads three dimensional CAD models to be n...

In this article, the authors present a general methodology for age-dependent reliability analysis of degrading or ageing components, structures and systems. The methodology is based on Bayesian methods and inference—its ability to incorporate prior information and on ideas that ageing can be thought of as age-dependent change of beliefs about reliability parameters (mainly failure rate), when c...

This study focuses on the numerical modelling of concentrated leak erosion of a cohesive soil by a turbulent flow in axisymmetrical geometry, with application to the Hole Erosion Test (HET). The numerical model is based on adaptive remeshing of the water/soil interface to ensure accurate description of the mechanical phenomena occurring near the soil/water interface. The erosion law governing t...

Aim of the study: The aim study was to determine range and conditions for formation piping hole canal found in Pieniny National Park May 2019. Material methods: scope research carried out included determination geotechnical characteristics subsoil on slope near along canal. Numerical calculations with finite element method were also GeoStudio program, which allowed assess possibilities soil def...

Abstract Piping systems are common in many architectures and designing such is often a complex task. Design automation of piping therefore universal research subject. Nonetheless, these still designed by hand as result their complexity. Consequently, costs associated with design high, especially for large-scale like ships chemical plants. The goal automatic pipe routing to reduce the time syste...
