Subsea Pipeline On Bottom Stability Analysis
Pipelines resting on the seabed are subject to the forces that can destabilize the pipe, leading to floatation or lateral movement. The stabilization requirements of the pipeline can be a major cost driver on subsea pipeline projects, especially in some shallow locations around the world, where the wave-induced current is an extremely challenging condition. Sometimes, costly stabilization requirements, such as trenching, anchoring, rock dumping, and mattressing, have therefore been used to ensure the stability of a pipeline on the seabed. Deepwater pipelines are typically stable on bottom due to the absence of wave-generated currents. However, certain deepwater regions around the world experience loop currents that may affect pipeline on-bottom stability. In addition, pipeline on-bottom stability design is critical in the whole life of pipeline design procedure.
The main purpose of pipeline on-bottom stability design is to choose the appropriate pipeline route, materials, size and convenient manufacture, installation, and maintenance method so that the pipeline can withstand probable design current and wave loads at a low cost. On-bottom stability calculations are performed to determine the minimum requirements for pipeline submerged mass. The required pipeline submerged weight has a direct impact on the required pipe laying tensions, installation stresses, and the pipeline configuration on the sea bottom. From the installation viewpoint, especially where spans are not a concern, the priority is to minimize the required pipeline submerged mass.
