Indirect Measurements of Added-Wave Resistance on an In-Service Container Ship

, 2020
This paper investigates a semi-empirical model used to estimate added-wave resistance on a ship sailing in waves. The model relies on measurements from a continuous monitoring system, and produces an estimate - the indirect measurement - of added-wave resistance, based on the difference between, on the one side, the measured power and, on the other ...

A Boundary Element Method for Motions and Added Resistance of Ships in Waves

Transactions of FAMENA, 2015
The accurate prediction of ship resistance in waves is nowadays of increased importance since it greatly influences ship performance regarding sustainable service speed and fuel consumption in seaways. Added resistance is considered as the longitudinal component of the second order mean force acting on a ship in waves and can be calculated from the ...

Estimation of Added Resistance of a Ship in Regular Waves

Brodogradnja : An International Journal of Naval Architecture and Ocean Engineering for Research and Development, 2011
Two methods of added resistance calculation are briefl y presented, one developed by Faltinsen, and the other by Salvesen. Both are based on the Salvesen, Tuck and Faltinsen linear strip theory, as they use it to defi ne the wave induced motions. The fi rst one obtains the added resistance by direct pressure integration, while the second one involves ...
