Pipeline Analysis Features Stress analysis of a pipeline in a finite element model requires special handling of the circular pipe cross-section if simple beam-column elements are used as in PipeNet. Point loads at arbitrary spacing and location Prescribed displacements (local and global coordinates) Arbitrarily or uniformly spaced field joints with reduced stiffness Two non-linear pipe moment-curvature models (Moment-curvature defined by the Ramberg-Osgood curve or based on a uniaxial stress-strain curve) General seabed profile including a cross-slope (3D) General pipeline profile in plan (3D) Non-linear vertical, axial and lateral soil support Modelling of column buckling (upheaval and snaking) Pipe air filled or fluid filled, submerged or in air Internal and external fluid pressures General variation of temperature along pipe axis General variation of initial tension along pipe axis End fixity: free, rigid, pinned Calculation of hoop stresses and true wall stresses Restart capability Output control and plot fileġ.2.3. Capabilities Two- and three-dimensional analysis Euler-Bernoulli beam-column elements Variable pipe diameter and wall thickness General specification of vertical, lateral, axial distributed loads (e.g. The theory on which PipeNet is based is described in the Volume 3 of the SAGE Profile User Manuals.ġ.2.2. In fact, an unlimited number of loading stages are possible with loading applied in any sequence following laydown. Thus, a typical pipeline analysis is defined by a laydown stage, followed by (for example) hydrotest loading in a second stage. Within each stage the loading is applied incrementally to follow the geometric and material non-linearities which may ensue. Analyses are divided into loading stages corresponding to different stages in the life of the pipeline. A schematic diagram depicting some of the programs 2D capabilities is shown in Figure 1.įigure 1: Schematic showing some features of pipe2D. lifting during trenching) as well as internal and external pressures and general temperature distributions. General forms of loading include : self weight (including piggy-back lines), lay tension, point loads (e.g. Its capabilities include non-linear pipe bending, non-linear soil response (bearing capacity, and axial and lateral frictional resistance), large deformation analysis and buckling. General PipeNet is a finite element program for two- and three-dimensional pipeline stress analysis. Validation report and certificate are available on the SAGE Profile installation CD.ġ.2.1. SAGE Profile finite element engine PipeNet has been validated and certified by Bureau Veritas.
PIPENET MANUAL VERIFICATION
The Software Verification and Validation Document, including more than 60 test problems and solutions, forms part of the SAGE Profile documentation as Volume 4 of this series. PipeNet has been subject to a rigorous Software Verification and Validation Plan following the IEEE Standard for software quality assurance.
PIPENET MANUAL MANUAL
The theory on which SAGE Profile is based is presented in SAGE Profile User Manual Volume 3. The utilisation of SAGE Profile Interface is described in the User Manual Volume 1. This manual provides a user orientated description of PipeNet and describes the form of data input and output. Normally, the GUI will handle user interaction with PipeNet. Volume 2 (this volume) of the set of documentation for SAGE Profile is concerned with the finite element analysis module PipeNet, forming the heart of the SAGE Profile system.
