Assessment of the Stability and Response of a Catamaran-Hull Ferry to Operational and Environmental Conditions

Kapal
Ship stability is a critical factor in the operation of a catamaran, especially when facing various sea conditions. The catamaran H-192, recently acquired by PT XY, is used as a case study in this research to assess its stability and response to ...

Construction and Demonstration of a Seaplane‐Type UAV‐Based High‐Precision GNSS‐A Seafloor Crustal Deformation Observation System

Earth and Space Science, Volume 12, Issue 7, July 2025.
Abstract The Global Navigation Satellite System—Acoustic combination (GNSS‐A) is used to observe seafloor crustal deformation by determining the global position of the seafloor with GNSS positioning and acoustic ranging between a sea surface platform and a transponder station located on the seafloor. However, GNSS‐A observations are currently conducted

Vertical stabilization of catamaran based on low-high gain feedback control and extended state observer

Zhongguo Jianchuan Yanjiu
ObjectiveThe heave and pitch motions of a catamaran under severe sea states vary drastically, and the amplitudes of the motions are too large, which seriously affects seaworthiness.

Mesohabitat Evaluation Reveals Variable Abundances and Habitat Choice in Juvenile Atlantic Salmon Across Diverse Habitats in the Main Stem of a Large Sub‐Arctic River

Ecology of Freshwater Fish, Volume 34, Issue 3, July 2025.
ABSTRACT Large main stem rivers typically provide a variety of mesohabitat types, but their abundance, distribution and role in providing habitat for juvenile salmonids have rarely been analysed. The quantity of meso‐scale habitats and their juvenile Atlantic salmon abundance was surveyed in the large sub‐arctic River Teno in northernmost Fennoscandia.

Software numerical study of the stresses that appear in the “FANCAT” catamaran`s structure in calm water

Annals of "Dunărea de Jos" University of Galaţi: Fascicle XI Shipbuilding, 2017
The main objective of this work is to study the stresses that occurs in the structure of FANCAT catamaran. The catamaran structure was designed using BV rules clasification for passenger vessels.

Practical evaluation of high-speed round bilge catamaran resistance

Annals of "Dunărea de Jos" University of Galaţi: Fascicle XI Shipbuilding, 2015
The accurate practical evaluation of the high-speed catamaran resistance in still water is a crucial problem in naval architecture. Even if a lot of research was carried out in this field, the accuracy of the speed-power prediction depends on the hull ...
