Computational Model of Unsteady Hydromechanics of Large Amplitude Gerstner Waves [PDF]

EPJ Web of Conferences, 2020
The computational experiments in the ship fluid mechanics involve the nonstationary interaction of a ship hull with wave surfaces that include the formation of vortices, surfaces of jet discontinuities, and discontinuities in the fluid under the ...

A FUNDAMENTAL STUDY ON MEASUREMENT OF HULL ROUGHNESS

Brodogradnja, 2020
In this study, an investigation on the hull roughness measurement of a new ship, a 160m class car ferry, was performed. The hull roughness measurement was conducted in the ferry’s pre-coated state before launching.

Development of an Autonomous Cleaning Robot with a Hydraulic Manipulator Arm for the Cleaning of Niche Areas of a Ship Hull

Journal of Marine Science and Engineering, 2023
Fouling organisms reduce a ship’s fuel efficiency and disturb the ecosystem. Therefore, the International Maritime Organization (IMO) and many nations have enacted laws that mandate periodic hull cleaning for removing fouling organisms. However, cleaning

Ship detection and classification based on cascaded detection of hull and wake from optical satellite remote sensing imagery

GIScience & Remote Sensing, 2023
Satellite remote-sensing provides a cost- and time-effective tool for ship monitoring at sea. Most existing approaches focused on extraction of ship locations using either hull or wake.
