PRCI On-Bottom Stability Simulator
PIPELINE ENGINEERING SOFTWARE & INDUSTRY TRAINING THAT SET THE PRODUCTIVITY STANDARD
Overview
Unburied submarine pipelines face unique challenges. The environments are as different as unrefined crude is from natural gas. In fact, it is a liquid pipeline environment as opposed to a solid (trenched) or above-ground pipeline. On-bottom pipelines face the additional stresses and strains of currents and wave action, and engineers need calculations that comply with additional standards to analyze them. The latest release of the PRCI On-Bottom Stability Simulator (OBS) extends its leadership in subsea pipeline engineering analysis with modernization, bug-fixes, and new functionalities.
On-Bottom Stability Challenges
Wave Modeling Complexity
Other models do not have the flexibility to allow user-defined parametersOBS enables Level 3 analyses, you can quickly update the model and include multiple wave seeds per run.
Legacy Software
Experience with previous versions of OBS revealed limits to its capabilities.The latest version of OBS has been modernized, with extended functionality, bug-fixes, and new features.
The PRCI On-Bottom Stability Simulator
The PRCI On-Bottom Stability Simulator is the world standard for subsea pipeline design and analysis. The latest version of this venerable software toolset has been updated and enhanced. Companies across the industry use it to calculate kinematics from 3-D irregular waves, hydrodynamic force, partial burial, and nonlinear models, as well as time-dependent interaction between pipeline and soil.
This software tool performs detailed analyses of specific pipeline sections subjected to specified environmental conditions. The new release consists of three levels, with Level 1 being used for quick simplified analysis, Level 2 for comprehensive detailed design and modeling (most used), and Level 3 for advanced and complex subsea pipeline design modeling.
The new interface was designed to maintain the overall layout and workflow of the previous version so existing users could quickly and easily become familiarized with the new features. These include structural database enhancements for storing and accessing project models, increased flexibility with user-defined parameters, and added plotting features. It now includes the absolute lateral static stability code check module following DNV-RP-F109 (2011).
