Transient Translational–Rotational Motion of an Ocean Current Converter Mooring System with Initial Conditions

Journal of Marine Science and Engineering, 2023
Systems of ocean current power generation are generally moored deep in the seabed. The mooring system is like ropes. The ropes are very long and can provide tension but not compression, and their dynamic displacement is large and unstable, which is ...

Coupled dynamics analysis of floating wind turbine mooring system under extreme operating gust

Applied Ocean Research
Extreme operational gust (EOG), defined by sudden increases in wind speed, is one of the most hazardous situations for wind turbines and the mooring system. A coupled aero-hydro-servo-elastic simulation model is developed using a dynamic link library and

Modelling and Simulation of Moored-Floating Structures Using the Tension-Element-Method [PDF]

Volume 2: CFD and FSI, 2018
The application of a discrete mooring model for floating structures is presented in this paper. The method predicts the steady-state solution for the shape of an elastic cable and the tension forces under consideration of static loads. It is based on a discretization of the cable in mass points connected with straight but elastic bars.

The Snap Tension Analysis of Taut‐Slack Mooring Line with tanh Method [PDF]

Mathematical Problems in Engineering, 2017
The continuous model is introduced, and the nonlinear partial differential equations of taut‐slack mooring line system are transferred to nonlinear algebraic equations through tanh method, and four solitary solutions are obtained further. At the same time, to express the results clearly, the curve surfaces of strains, displacements, and tension are ...

Understanding exam access arrangements in practice: Challenges and opportunities

British Educational Research Journal, EarlyView.
Abstract Secondary students with specific learning difficulties (SpLD) often face challenges with academic tasks, particularly with high‐stakes examinations. Exam access arrangements (EAA) are provided as reasonable adjustments to reduce disadvantage for students with SpLD.

Dynamic Response of an Offshore Floating Wind Turbine at Accidental Limit States—Mooring Failure Event

Applied Sciences, 2022
This paper investigates the dynamic response of a fully nonlinear model of a DeepCWind floating offshore wind turbine (FOWT) after one of its three-catenary mooring systems is broken.

Study on the Tension Mooring of the Floating Ocean Structures

Journal of the Society of Naval Architects of Japan, 1985
The tension mooring of the floating ocean structures seems promising to expand the ocean space exploitation. This kind of mooring method becomes relatively inexpensive in deep ocean, and has many advantages such that it can suppress the motion of the floating structures and needs only minimum mooring space.This paper presents the results of the ...

Emotional nourishment begets academic coping during the primary to secondary school transition

British Educational Research Journal, EarlyView.
Abstract The transition from primary to secondary school is widely viewed as the most demanding in a child's educational journey. Despite a wealth of research on this transition, little is known about the children's ‘lived experience’ of it across different contexts.

Erwin Schrödinger und die Versuchungen der (Wissenschafts‐)Biografik: Vorurteilsgefüge und Mechanismen der Skandalisierung

Berichte zur Wissenschaftsgeschichte, EarlyView.
Since late 2021, serious allegations have been made against physicist Erwin Schrödinger, ranging from pedophilia to serial sexual abuse. These accusations have significantly tarnished the Nobel Prize winner's public reputation. The ongoing debate has repeatedly raised the question of whether, and to what extent, these grave allegations are justified ...

Effects of shared lines with different materials on mooring response of the floating wind farm

Zhongguo Jianchuan Yanjiu
ObjectivesThis paper investigates the impact of shared lines with different materials on the dynamic response of floating wind farms in order to design a rational shared mooring system. MethodsFirst, shared mooring and traditional (without shared cables)
