A DDQN-Guided Dual-Population Evolutionary Multitasking Framework for Constrained Multi-Objective Ship Berthing

open access: yesJournal of Marine Science and Engineering
Autonomous ship berthing requires advanced path planning to balance multiple objectives, such as minimizing berthing time, reducing energy consumption, and ensuring safety under dynamic environmental constraints.

The effect of early berthing prospects on the energy efficiency operational index in oil tanker vessels. [PDF]

open access: yesIOP Conference Series: Materials Science and Engineering, 2016
Marine pollution is one of the main concerns of our society. In order to reduce air pollution produced by ships, the International Maritime Organization has developed technical, operational and management measures. Part of the operational measures refers

Analysis of Allowable Berthing Velocity by Ship Size considering Designed Energy [PDF]

open access: yesKorea Society of Coastal Disaster Prevention, 2021
The berthing velocity is the factor that has the greatest influence on the berthing energy. For the vessel to berth safely, it should not exceed the appropriate berthing velocity. In addition, when the vessel is berthing, it should be berthed with berthing energy smaller than the energy absorption of the fender.

Energy Optimization of the ‘Shore to Ship’ System—A Universal Power System for Ships at Berth in a Port [PDF]

open access: yesSensors, 2020
One of the most effective methods of limiting air pollution emissions by ships at a berth in a port is the power connection of ships to the on-shore system. “Shore to Ship” (STS)—A universal system for the connection of the ship’s electrical power network with the on-shore network—ensures the adoption of the voltage and frequency of the on-shore ...

Electrical characteristics of cold ironing energy supply for berthed ships [PDF]

open access: yesTransportation Research Part D: Transport and Environment, 2015
The reduction of emissions in harbours is of particular importance due to the proximity to human habitation. Vessels normally run onboard generators, typically using diesel fuel, to provide the service loads while berthed. New and upcoming regulations aim to decrease emissions from shipping, and coupled with increased environmental consciousness of ...

Expected electromagnetic environment at the energy infrastructure facilities of remote ports (berths)

open access: yesJournal of Physics: Conference Series, 2021
Abstract The article deals with the issues of electromagnetic compatibility of coastal and floating objects in the waters of ports (berths). The subject of the study is the processes occurring in the electrical network when powering ships of the technical fleet and floating objects from the shore, which determine the need for automated ...

Optimal ship berthing plans [PDF]

open access: yes, 1989
A ship berthing plan assigns surface vessels a berth prior to their port entrance, or reassigns ships once in port to allow them to accomplish in a timely manner maintenance, training, and certification events which build readiness for future operational

Data-driven ship berthing forecasting for cold ironing in maritime transportation [PDF]

open access: yes, 2022
Cold ironing (CI) is an electrification alternative in the maritime sector used to reduce shipborne emissions by switching from fuel to electricity when a ship docks at a port.

Ship nonlinear-feedback course keeping algorithm based on MMG model driven by bipolar sigmoid function for berthing

open access: yesInternational Journal of Naval Architecture and Ocean Engineering, 2017
Course keeping is hard to implement under the condition of the propeller stopping or reversing at slow speed for berthing due to the ship's dynamic motion becoming highly nonlinear. To solve this problem, a practical Maneuvering Modeling Group (MMG) ship
