Dynamic Analysis of Offshore Spar Platforms

Defence Science Journal, 2003
Offshore spar platform is a compliant offshore floating structure used for deep water applications for drilling, production, processing, storage and offloading of ocean deposits. The offshore spar platform is modelled as a rigid body with six degrees-of-freedom (DOFs), connected to the sea bed by multicomponent catenary cables which consist of a ...

Comparative Investigation of Coupled Dynamic Mechanisms of Floating Vertical-Axis Wind Turbines Supported by Different Platform Configurations

Energies
Dedicated platforms for floating vertical-axis wind turbines (VAWTs) require an in-depth understanding of their strongly unsteady coupled dynamics, yet the effects of platform configuration on motion stability, aerodynamic loading, and wake recovery ...

Design Optimization for a Truncated Catenary Mooring System for Scale Model Test

Journal of Marine Science and Engineering, 2015
One of the main aspects when testing floating offshore platforms is the scaled mooring system, particularly with the increased depths where such platforms are intended.

A Spar Modelling Platform Case Study: Skynet 5

Safety and Reliability, 2012
AbstractThis paper documents a case study into the Availability, Reliability and Maintainability (AR&M) modelling activity undertaken for the Skynet 5 Beyond Line Of Sight (BLOS) service programme between January 2006 and July 2011. The AR&M modelling activity was completed using the Monte Carlo simulation tool SPAR, produced by Clockwork Solutions ...

Predictive Ability of Plasma p‐tau217 for β‐Amyloid Status: A Prospective Multicenter Study

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective Plasma tau phosphorylated at threonine 217 (p‐tau217) measured with fully automated platforms has shown high accuracy for Alzheimer's disease (AD) diagnosis, but real‐world multicenter data remain limited. We aimed to validate the diagnostic performance of p‐tau217 for identifying AD pathology in a real‐world multicenter cohort ...

Investigation into the Potential Use of Damping Plates in a Spar-Type Floating Offshore Wind Turbine

Journal of Marine Science and Engineering
Spar is one of the promising floating platforms to support offshore wind turbines. Wind heeling moment is large in the case of floating offshore wind turbines and, therefore, it is important to reduce the pitch motion of the floating platform. To address

Memory and Resting‐State Connectivity in Acute Transient Global Amnesia: A Case–Control fMRI Study

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Background and Objectives Transient global amnesia (TGA) is a striking model of isolated amnesia. While hippocampal lesions are well described, the network‐level mechanisms and the precise neuropsychological profile remain debated. Our objective was thus to characterize functional and neuropsychological correlates of acute TGA and their ...

An Epigenetic Fate Converter Based on Nuclei‐Targeting Lipid Nanoparticles Drives Neuronal Programming of Stem Cells for Spinal Cord Repair

Advanced Functional Materials, EarlyView.
Schematic illustration of LNP‐MPG nuclei‐targeting delivery of HMW‐FGF2 promoting histone acetylation to regulate the fate of DPSCs and treat spinal cord injury. LNPs components include pHMW‐FGF2 plasmid, DSPC, Dlin‐MC3‐DMA, cholesterol, and PEG2000, and are modified with MPG to form HMW‐FGF2@LNP‐MPG (HLM). HLM nuclei‐targets DPSCs to deliver HMW‐FGF2,

Response of a Spar Platform Under the Occurrence of Extreme Waves

Volume 2: Structures, Safety and Reliability, 2011
In this note, the response of a Spar Platform is studied when subject to very high waves. The novelty of this paper consists in adopting the Quasi Determinism (QD) theory in its first formulation for the determination of the response of the structure. In fact, one of the peculiarities of QD theory is that it can be adopted under any boundary condition.
