ADDED RESISTANCE OF SHIPS IN QUARTERING SEAS [PDF]

open access: yes, 2013
In this paper, the 3D panel method of NTUA-SDL for calculating the added resistance of a ship in bow seas has been extended and validated for the quartering seas case. At first we studied the drift force on a semi-submersible in quartering seas.

Ship roll stabilization control with low speed loss [PDF]

open access: yes, 2014
Large roll motion induced by waves can severely affect the ability of vessels and the speed will loss due to added resistance which caused by ship motions, especially in moderate to high sea states. With increasing needs of fuel efficiency and greenhouse

The Effects of Added Reinforcers on Resistance to Change [PDF]

open access: yes, 2005
The fundamental unit of behavior, defined by the discriminated operant, can be reduced to the three-term contingency, which includes an antecedent stimulus, a response, and a reinforcing consequence. Behavioral momentum theory suggests that resistance to disruption (i.e., resistance to change) of operant behavior is governed by the relation between the

NUMERICAL SIMULATION OF SHIP NAVIGATION IN ROUGH SEAS BASED ON ECMWF DATA

open access: yesBrodogradnja, 2021
Recently, several changes have been observed in the Earth’s environment. This is also applicable to the ocean environment. The concept of weather routing has been applied for ship navigation for a long time.

Experimental Investigation of Added Resistance of a Ship using a Hydroelastic Body in Waves

open access: yesInternational Journal of Technology, 2022
Ship resistance is an important characteristic to predict in the preliminary design stage. Proper prediction of ship resistance implies the fulfillment of the required speed and power of a ship.

Determination of Seakeeping Performance for a Case Study Vessel by the Strip Theory Method

open access: yesPolish Maritime Research, 2020
The increase of seakeeping performance is of particular importance for car and passenger ferries, service ships in the gas and oil extraction industry and offshore wind power farm industry, as well as for special purpose ships (including military ...

Assessment of the Influence of Added Resistance on Ship Pollutant Emissions and Freight Throughput Using High-Fidelity Numerical Tools

open access: yesJournal of Marine Science and Engineering, 2022
The reduction of ship pollutants is a key issue in the international agenda. Emissions estimation is usually based on standard calculations that consider the different scenarios of ships.

Prediction of resistance and propulsion performances using calm-water and resistance tests in regular head waves of a 1,800 TEU container ship

open access: yesInternational Journal of Naval Architecture and Ocean Engineering, 2022
This paper predicts resistance and propulsion performances in regular and irregular head waves of a 1800 TEU container ship. ‘Calm-water tests’ and ‘resistance test in regular waves’ have been performed. Methods applied are the LVM-W and the revised ITTC-

Artificial Neural Network Model for the Evaluation of Added Resistance of Container Ships in Head Waves

open access: yesJournal of Marine Science and Engineering, 2021
The decrease in ship added resistance in waves fits into both the technical and operational measures proposed by the IMO to reduce the emissions of harmful gases from ships. Namely, the added resistance in waves causes an increase in fuel consumption and
