Evaluation of the Effect of Container Ship Characteristics on Added Resistance in Waves [PDF]

Journal of Marine Science and Engineering, 2020
Added resistance in waves is one of the main causes of an increase in required power when a ship operates in actual service conditions. The assessment of added resistance in waves is important from both an economic and environmental point of view, owing ...

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

Journal 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

Experimental and Numerical Investigation of the Added Resistance in Regular Head Waves for the DTC Hull

Journal of Marine Science and Engineering, 2023
Reducing the added resistance in waves has become a crucial aspect of today’s ship design. The added resistance in waves is traditionally considered proportional to the square of wave height.

Increase of the Ship Fuel Consumption Due to Added Resistance in Waves

Journal of Sustainable Development of Energy, Water and Environment Systems, 2017
Added resistance in waves is the second-order steady force dependant on the ship motions. It significantly affects ship operability and cause speed loss. Therefore the required power and fuel consumption of a ship advancing in a seaway are increasing. In
