Numerical Simulation Study of the Motion Characteristics of Autonomous Underwater Vehicles During Mooring Lurking Procedure

open access: yesJournal of Marine Science and Engineering
A two-dimensional coupled dynamics model for a moored autonomous underwater vehicle (AUV) was developed using the lumped mass method for mooring cable dynamics and the Newton-Euler method for rigid body dynamics.

Extreme Value Analysis of Statistically Independent Stochastic Variables [PDF]

open access: yes한국해양공학회지, 2019
An extreme value analysis (EVA) is essential to obtain a design value for highly nonlinear variables such as long-term environmental data for wind and waves, and slamming or sloshing impact pressures.

Mooring optimization design based on neural network and genetic algorithm

open access: yesZhongguo Jianchuan Yanjiu, 2017
[Objectives] In order to maintain the stability of the position of a ship, a mooring system is required to reduce the translational motion of floating structures.[Methods] Taking a pipe-laying vessel in the South China Sea as an example, it is possible ...

Accurate computation of the Moore–Penrose inverse of strictly totally positive matrices

open access: yesJournal of Computational and Applied Mathematics, 2019
The computation of the Moore-Penrose inverse of structured strictly totally positive matrices is addressed. Since these matrices are usually very ill-conditioned, standard algorithms fail to provide accurate results. An algorithm based on the factorization and which takes advantage of the special structure and the totally positive character of these ...

Feasibility Study for Development of New Stationkeeping System [PDF]

open access: yes한국해양공학회지, 2019
In this study, experiments with a floater using flapping foils were performed to develop a new station keeping system that can maintain its position in waves without mooring lines. The foils applied to this system generate thrust using wave energy.

A Structuralist approach to women’s position in George Moore’s Esther Waters

open access: yesRumeliDE Dil ve Edebiyat Araştırmaları Dergisi, 2020
Structuralism defines the relationship between the part and the whole. This study aims to analyse George Moore’s Esther Waters (1894) in terms of structuralist approach. The surface structure of the novel focuses on Esther raising her son alone. In terms of syntagmatic relation, Esther has an extramarital sexual intercourse with William, raises her son

Influence and optimization of mooring angle in multi-point mooring positioning system

open access: yesZhongguo Jianchuan Yanjiu, 2018
[Objectives] In this paper, a method for calculating the static restoring force of a mooring system is proposed in order to optimize the mooring angle and meet the strength requirements of mooring lines. [Methods] Using this method, a study is conducted on the influence of the mooring angle on the static restoring force and heading of the platform, and

Effect of triangle plate positioning on mooring line tension of single point mooring system

open access: yesIOP Conference Series: Earth and Environmental Science
Abstract The marine transportation of crude oil from tankers to final terminals is facilitated using pipelines and oil terminals. The predominant form of the terminal is the Single Point Mooring system. The system is crucial as it anchors tankers and transfers crude oil from the ship to the system using floating hoses.
