This paper addresses a practical problem: “Under which coverage of buoyancy modules, would the Vortex Induced Vibration (VIV) excitation on buoyant segments dominate the response?” This paper explores the excitation competition between bare and buoyant segments of a 38 meter long model riser. The source of data is a recent model test, conducted by SHELL Exploration and Production at the MARINTE...

H₂S plasma created by an electrode-less radio-frequency discharge was used to modify the surface properties of the polymer polyethylene terephthalate. X-ray photoelectron spectroscopy, secondary ion mass spectrometry and atomic force microscopy were used to determine the evolution of the surface functionalities and morphology. A very thin film of chemically bonded sulfur formed on the surface w...

Abstract The Both bonded and unbonded prestressing tendons may be used to reinforce post-tensioned (PT) concrete members. binding state of have an impact on how well different types PT elements function in flexural shear loads. Inverted-U shape reinforcement was experimentally enhance the behavior structural elements. obtained results confirmed proposed model’s accuracy for both slabs beams (bo...

The aim of the Special Issue (SI) was to publish original and high-quality research papers that deal with model developments based on mathematical, numerical, experimental models associated flexible floating or submerged structure applications in discipline marine engineering [...]
