METHOD FOR THE EVALUATION OF ON-BOTTOM STABILITY OF SUBSEA PIPELINE BY DYNAMIC EMBEDMENT

摘要

the invention for the production of oil and gas pipelines and subsea flow lines and installation of structures such as pipes, seabed soil in the settlements reflect more accurate dynamic subsea safety assessment methods are available. The process according to the invention, (a) Pipe Specification (pipe data), a phase to extract the basic data including the environment Spec (environmental data), and soil Spec (soil data), (b) based on the basic data in, and extracting a load (load) factor to be applied to the pipe, (c) extracting a resistance (resistence) factor restricting the movement of the pipe on the basis of the basic data, (d) the load factor and in case the resistance factor, requires a phase to extract the water weight, (e) to prepare and design the underwater weight of the required criteria, and including the step of determining the compliance of the design criteria, the step (c) is a dynamic that through the installation analysis extract resistivity factor, and performs the failure to meet the design criteria in the step (e), the step by increasing the pipe movement strokes the by the re dynamic settlement analysis (c) to (e) and the features. ;
