TKP-Net: A Three Keypoint Detection Network for Ships Using SAR Imagery

open access: yesIEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing
Remote-sensing ship monitoring is a crucial area of research with key applications in military and civilian fields. The ability to extract information, such as ship length, width, and heading from remote-sensing data, particularly from synthetic aperture

Visual Direction Indication for Ships [PDF]

open access: yesJournal of Navigation, 1966
Already many years ago Captain A. Vreugdenhil proposed the use of visual aids to supplement the sound signals used to indicate changes in heading. His idea of using visual aids was based on the erratic behaviour of sound and the consequent possibility of misinterpretation of sound signals.Choosing between two possible systems, the directional ...

Maritime rights, obligations, and liabilities of intelligent ships from the perspective of risk distribution

open access: yesJournal of International Maritime Safety, Environmental Affairs, and Shipping, 2023
The technical energy and economic benefits contained in ship intelligence will drive the maritime industry to continue to develop in this direction. In this process, intelligent ship activities will pose challenges to existing maritime law, and existing ...

Visual Direction Indication for Ships [PDF]

open access: yesJournal of Navigation, 1967
There is no doubt that everyone is agreed that a combination of visual and sound signals are a necessity, but, in view of the large disparity in the speeds of light and sound, the method of achieving this has not really been agreed upon, although a few countries supported the system of synchronizing the light and sound signals, thus bringing about the ...

Engagement-Scenario-Based Decoy-Effect Simulation Against an Anti-ship Missile Considering Radar Cross Section and Evasive Maneuvers of Naval Ships

open access: yes한국해양공학회지, 2021
The survivability of a naval ship is the ability of the ship and its onboard systems to remain functional and continue a designated mission in man-made hostile environments.

Challenges and development directions of membrane bioreactors operated on passenger ships in international shipping

open access: yesActa Universitatis Lodziensis. Folia Biologica et Oecologica, 2021
In membrane bioreactor (MBR) technology, the activated sludge method is integrated with the separation of solid particles by ultrafiltration (UF). The technology ensures a high effluent quality, a shortened hydraulic retention time and a long sludge age that promotes slowly growing microorganisms and low sludge production.

Prediction of ship power based on variation in deep feed-forward neural network

open access: yesInternational Journal of Naval Architecture and Ocean Engineering, 2021
Fuel oil consumption (FOC) must be minimized to determine the economic route of a ship; hence, the ship power must be predicted prior to route planning. For this purpose, a numerical method using test results of a model has been widely used.

Wake-Responsive AUV Guidance Assisted by Passive Sonar Measurements

open access: yesJournal of Marine Science and Engineering
To make an Autonomous Underwater Vehicle (AUV) chase a moving target ship that generates wake, wake-responsive guidance can be used. This scenario is applicable to making an underwater torpedo pursue a moving target ship until hitting the target.

Estimation of Propagation Speed and Direction of Nonlinear Internal Waves from Underway and Moored Measurements

open access: yesJournal of Marine Science and Engineering, 2021
Propagation speed and direction of nonlinear internal waves (NLIWs) are important parameters for understanding the generation and propagation of waves, and ultimately clarifying regional ocean circulation.
