Synthesis and Optimization of Submarine Pipeline Routes
Traditionally, the selection of a pipeline route for offshore applications has been manually performed by the engineer, by a quick inspection of the seabottom bathymetry and the available information regarding obstacles. Eventually the evaluation of a given route could be performed using analysis tools, but in any case the process is highly dependent on the expertise of the engineer. In this co...
متن کاملAccidental Limit State of Submarine Pipeline: Trawl Gears Pull-Over Loads and Effect of Free Span
Submarine pipelines failures lead to oil spills in water and may even lead to explosions with heavy financial and environmental damages. Trawl gear is one of the main factors in the failure of the submarine pipelines. In this paper, sensitivity analysis is performed on influence of height and span length alternations on the response of pipeline against the traction caused by trawling pull-over ...
متن کاملForces Acting on the Seabed around A Pipeline in Unidirectional Ocean Currents
In this study, the hydrodynamic forces acting on the seabed around the pipeline in unidirectional ocean currents have been investigated numerically. Two types of seabed are considered, i.e., plane and distorted seabed. The influences of gap between pipeline and seabed on the distribution of forces along the seabed are studied in detail. Computational results show that the pressure at the upstre...
متن کاملA detailed seabed signature from Hurricane Sandy revealed in bedforms and scour
[1] On 30 October 2012, Hurricane Sandy made landfall near Brigantine New Jersey bringing widespread erosion and damage to the coastline. We have obtained a unique set of high-resolution before and after storm measurements of seabed morphology and in situ hydrodynamic conditions (waves and currents) capturing the impact of the storm at an inner continental shelf field site known as the ‘‘Redbir...
متن کاملNumerical Modeling of Seismic-induced Soil Response Around Submarine Pipeline
Seismic-induced pore pressure and effective stresses in the saturated porous seabed under seismic loading are the main factors that govern the overall stability of submarine pipelines. In most of the previous investigations for the seismic-induced dynamic response around a submarine pipeline have been limited to two-dimension cases. In this paper, a three-dimensional finite element model includ...
