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 ... -
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 ... -
Fatigue Analysis of Inter-Array Power Cables between Two Floating Offshore Wind Turbines Including a Simplified Method to Estimate Stress Factors
Beier, Dennis; Schnepf, Anja; Van Steel, Sean; Ye, Naiquan; Ong, Muk Chen (Journal article; Peer reviewed, 2023)The use of floating offshore wind farms for electrical energy supply is expected to rise significantly over the coming years. Suspended inter-array power cables are a new design to connect floating offshore wind turbines ... -
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 ... -
State-of-the-Art Review of Vortex-Induced Motions of Floating Offshore Wind Turbine Structures
Yin, Decao; Passano, Elisabeth; Jiang, Fengjian; Lie, Halvor; Wu, Jie; Ye, Naiquan; Sævik, Svein; Leira, Bernt Johan (Peer reviewed; Journal article, 2022)The motivation for this study is the fast development of floating offshore wind energy and the immature methodology and engineering practice related to predictions of vortex-induced motions (VIM). Benefiting from the oil ... -
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 ... -
