Prediction of Combined IL and CF VIV Response of Deepwater Risers [PDF]

, 2017
Deepwater risers are susceptible to Vortex Induced Vibrations (VIV) when subjected to currents. When responding at high modes, fatigue damage the in in-line (IL) direction may become equally important as the cross-flow (CF) components.

Atypical Long Barrows in the Cöeby Neolithic Cemetery (Trédion, Morbihan, France)? The Contribution of Electrical Surveys

Archaeological Prospection, EarlyView.
ABSTRACT The Coëby Neolithic cemetery, located in the commune of Trédion (Morbihan, France) and discovered in 1986, has been for several years the subject of a research programme focused on studying the various megalithic structures present. The spatial distribution of these remains highlights an unusual occupation of the territory, organized according

FIV Energy Harvesting from Sharp Edge Square and Diamond Oscillators

International Journal of Maritime Technology, 2019
The horizontal kinetic energy of the fluid flow, from on-land wind to ocean tidal stream, is one of the most promising sources of the energy. In the field of renewable energies, power extraction from Flow Induced Vibration (FIV) of bluff bodies is a fast

OMAE2017-61768 VIV Responses of Riser With Buoyancy Elements: Forced Motion Test and Numerical Prediction [PDF]

, 2017
Steel Lazy Wave Riser (SLWR) is an attractive deep water riser concept. When subjected to vortex induced vibrations (VIV), the vortex shedding process of the buoyancy element and the bare riser section will be different due to the difference in diameter.

Critical Success Factors and Stakeholder Influence for Environmental, Social and Governance Assessment and Reporting

Business Strategy and the Environment, EarlyView.
ABSTRACT Environmental, Social and Governance (ESG) assessment criteria have drawn substantial attention by investors in recent years. ESG factors have been considered by investors to create greater wealth and better investment decisions and opportunities. However, there are ambiguities about ESG assessment and reporting with issues of transparency and

The Effect of Shifting Natural Frequency on the Reduction of Vortex-Induced Vibrations of Marine Risers

International Journal of Coastal and Offshore Engineering, 2017
Many procedures suggest for reduction of responses of riser to Vortex Induced Vibrations (VIV). Natural frequencies of marine risers is an important parameter that can affect the responses of riser to VIV.

Numerical simulation in time domain to study cross-flow VIV of catenary riser subject to vessel motion-induced oscillatory current

International Journal of Naval Architecture and Ocean Engineering, 2020
The present study proposes a time domain model for the Vortex-induced Vibration (VIV) simulation of a catenary riser under the combination of the current and oscillatory flow induced by vessel motion.
