There are many ways to produce pseudo-random computer simulations of random functions correlated in space and/or time. The simulation mathematics may be performed in time and space domains or in the corresponding frequency domains. In either case,…
Traditional design practices for offshore pipelines attempt to ensure stability along the entire pipeline system. In shallow water, the standard practice requires the burial of pipeline systems resulting in increased construction costs from trenching…
The state-of-the-art in Pipeline stability design has been changing very rapidly recently. The physics governing on-bottom stability are much better understood now than they were eight years ago. This is due largely because of research and large…
The scope of work for phase I of PR-453-134504 included implementation of the Verley and Lund [1] clay soil model in Level 2 of the PRCI on-bottom stability (OBS) software. Throughout the implementation process a number of apparent discrepancies…

The PRCI software (version 3.0) which assesses hydrodynamic stability of submarine pipelines was revised. There are three 'levels' of analysis available in this software. The main technical revisions are for:

In addition, the obtaining of surface and near-surface oceanographic and meteorological data provides the opportunity to develop mathematical relationships between surface and bottom conditions for a major storm or hurricane. From these…
A comprehensive design aid addressing all aspects of submarine pipeline design, and specifically detailing the stability design procedures and process.
The extension of the PRCI on bottom stability (OBS) software's applicability to shallow water is assessed. Version 3 of the software has a limitation on water depth
