Algorithmic formulation of clay and sand pipe–soil interaction models for on-bottom stability analysis
Longva, Vegard; Ji, Guomin; Sævik, Svein; Ye, Naiquan; Gjøsteen, Janne Kristin Økland; Giertsen, Egil; Wang, Yanbin (Peer reviewed; Journal article, 2021)This paper presents a new algorithmic formulation of the clay and sand pipe–soil interaction models recommended by the DNV-RP-F109 code for dynamic on-bottom stability analysis of submarine pipelines. The pipe–soil force ... -
An anisotropic friction model in non-bonded flexible risers
Dai, Tianjiao; Sævik, Svein; Ye, Naiquan (Journal article; Peer reviewed, 2018-05)The present paper addresses small scale friction tests and an anisotropic friction model to predict friction for the interface between the anti-wear tape and tensile armors in non-bonded flexible risers. Small scale friction ... -
Comparison study of umbilicals' curvature based on full scale tests and numerical models
Dai, Tianjiao; Sævik, Svein; Ye, Naiquan (Journal article; Peer reviewed, 2016)A full scale test was carried out for a dynamic steel tube umbilical under combination of tensile and bending loads. The purpose of the test was to investigate the behavior of the dynamic bending under complex loading ... -
Effect of lay angle of anti-buckling tape on lateral buckling behavior of tensile armors
Zhou, Chongyao; Sævik, Svein; Ye, Naiquan; Ji, Guomin (ASME Proceedings | Pipeline and Riser Technology;OMAE2015-41527, Chapter, 2015-06)During deep water flexible pipe installation, the pipe is normally free hanging in empty condition from the installation vessel to the seabed. This will introduce large hydrostatic forces to the pipe causing true wall ... -
Friction models for evaluating dynamic stresses in non-bonded flexible risers
Dai, Tianjiao; Sævik, Svein; Ye, Naiquan (Journal article; Peer reviewed, 2017-09)This paper addresses friction models used for evaluating dynamic stresses in non-bonded flexible risers. A review of the most commonly used methods to model friction between layers in such structures was performed. Four ... -
The Effect of Stick Stiffness of Friction Models on the Bending Behavior in Non-Bonded Flexible Risers
Dai, Tianjiao; Ye, Naiquan; Sævik, Svein (ASME Proceedings | Pipelines, Risers, and Subsea Systems;OMAE2017-62644, Chapter, 2017)This paper investigates the effect of stick stiffness on the bending behavior in non-bonded flexible risers. The stick stiffness was normally implemented in the friction model for calculating the friction stress between ... -
