World Pipelines,

PRCI has announced the release of a major software upgrade to its subsea pipeline design and analysis tool, the On-Bottom Stability Simulator (OBS). The PRCI OBS software tool is a specialty application for the analysis of on-bottom pipeline stability in subsea applications.

The new release, version 4.0, includes modernisation updates, bug fixes, and the addition of new software functionalities. The latest interface was designed to maintain the overall layout and workflow of the previous version so that existing users can quickly and easily become familiarised with the new features.

OBS features include the calculation of kinematics from 3D irregular waves, several hydrodynamic force models, models for partial burial, non-linear, time dependent interaction between pipeline and soil (sand and clay), and non-linear pipeline material properties (for boundary elements). These features allow for detailed analysis of specific pipeline sections subjected to specified environmental conditions. Additionally, the new release consists of three levels with Level 1 being used for quick simplified analysis, Level 2 for comprehensive detailed design and modelling, and Level 3 for advanced and very complex subsea pipeline design modelling.
