Numerical modelling of erosion and sedimentation around offshore pipelines [PDF]
, 1990 In this paper a numerical model is presented for the description of the erosion and sedimentation near pipelines on the sea bottom. The model is based on the Navier-Stokes equations and the equation of motion and continuity of sediment.\ud \ud The ...

Research on Magnetic Memory Detection of Submarine Pipeline Suspended Damage Section
Shiyou jixie, 2021 Submarine pipelines are an important means of transportation to ensure the continuous development of offshore oil and gas fields. Submarine pipelines are susceptible to corrosion and external forces that cause defects and lead to failure during ...

Prediction on running time of pigs in submarine pipelines
You-qi chuyun, 2022 The running time of pigs in submarine pipelines is an important reference for pig receiving operation. In order to identify the factors that influence the running time of pigs, the correlation degree of pipeline mileage, pipeline inlet/outlet pressure ...

Variation of tow force with velocity during offshore ploughing in granular materials [PDF]
, 2012 Pipeline plough behaviour has been investigated by means of reduced scale physical model testing. A testing programme was devised to investigate the influence of permeability, relative density, and plough depth on the associated tow force measured ...

Evolution of structural response to post-trenching of free-spanning submarine pipeline
You-qi chuyun, 2022 The free-spanning submarine pipeline has complex interaction with the surrounding soil during post-trenching, but its structural response mechanism is still not verified by physical simulation. Herein, a submarine pipeline model was designed based on the
