PRCI Releases Major Upgrade for the On-bottom Stability Software Tool


Wed, August 07, 2019

Chantilly, Virginia, USA, August 07, 2019 —


PRCI announced today the release of a major software upgrade for 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 modernization 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 familiarized with the new features.

OBS features include the calculation of kinematics from 3-D 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 (3) levels with Level 1 being used for quick simplified analysis, Level 2 for comprehensive detailed design and modeling, and Level 3 for advanced and very complex subsea pipeline design modeling.

Existing software users are encouraged to upgrade to the latest version, as all previous versions of the software will no longer be supported as early as August 2020.
