Assessment of the Roll Derivatives of Different Surface Ships Based on Numerical Pure Roll Simulation

open access: yesJournal of Marine Science and Engineering, 2022
Among the 6 degrees of freedom (6-DoF), excessive roll motion is the most dangerous cause of ships capsizing. However, when analyzing the maneuverability of surface ships, the roll components have usually been ignored.

Factors affecting the survival of harbor (Phoca vitulina) and gray seal (Halichoerus grypus) juveniles admitted for rehabilitation in the UK and Ireland

open access: yesMarine Mammal Science, Volume 39, Issue 2, Page 462-480, April 2023., 2023
Abstract The UK shores are home to approximately 40% of the world's population of gray seals (Halichoerus grypus) and 40% of Europe's harbor seals (Phoca vitulina). Stranded juvenile seals of both species are frequently rescued and admitted for rehabilitation. This study investigates the causes of P. vitulina and H.

A genealogy of the food bank: Historicising the rise of food charity in the UK

open access: yesTransactions of the Institute of British Geographers, Volume 47, Issue 3, Page 618-634, September 2022., 2022
This paper presents a genealogical account that challenges the typical origin stories told about food banks in the UK. It situates their emergence within a set of historically contingent practices, alliances, and struggles, many of which are nowadays forgotten.

Discrete Wavelet Transform‐based Approach of Real‐time Wave Filtering for Dynamic Positioning of Marine Vessels

open access: yesMathematical Problems in Engineering, Volume 2022, Issue 1, 2022., 2022
The ongoing development of deep‐sea resources has contributed toward the widespread use of dynamic positioning (DP) systems that can operate in arbitrary sea areas without the limitation of operating water depth compared to mooring systems. The second‐order slowly varying forces can be compensated by DP feedback control.

THE SIMULATION OF SKEG EFFECT TO BARGE RESISTANCE CALCULATION USING CFD-RANS OPENFOAM

open access: yesWave: Jurnal Ilmiah Teknologi Maritim, 2020
The paper discusses the significance of different types of skegs in a barge toward the pressure, fluid velocity and the ship’s total resistance. There are three kinds of skeg configurations: barge without skegs, skegs without deflection, and skegs with ...
