A LID APPROACH FOR PREDICTING WAVE INDUCED MOTIONS OF TRIMARAN IN REGULAR WAVES

Brodogradnja, 2019
The wave induced motions of a trimaran sailing in regular head waves were predicted by using the three dimensional boundary integral method. Large wave elevation on the free surface in between the trimaran’s main-hull and the outriggers occurred at some ...

An experimental study on the open water characteristics of a ship propeller in waves

Applied Ocean Research
This paper deals with the assessment of the propeller performances in waves, by means of experimental open water tests. The focus of this study is on the propeller behaviour, neglecting, at this stage, the interaction with the hull dynamics.

Numerical and Experimental Study on Seakeeping Performance of a High-Speed Trimaran with T-foil in Head Waves

Polish Maritime Research, 2019
The longitudinal motion characteristics of a slender trimaran equipped with and without a T-foil near the bow are investigated by experimental and numerical methods. Computational fluid dynamics ( CFD) method is used in this study.

Numerical Investigation of Ship Responses in Calm Water and Regular Head Waves

, 2022
In order to design fuel efficient ships and install right machinery onboard, ship designers need to know the interaction effects between hull, propeller and appendages in realistic operating conditions. Neglecting the interaction effects may result in under/over-prediction of the required power.

The performance of bow foils in irregular and oblique waves

Applied Ocean Research
Bow foils are an emerging energy saving device that utilise wave energy to improve the efficiency of ships operating in waves, through both a reduction in ship motions and the generation of additional thrust.

SPIV Measurement for a Self-propelled Ship in Regular Head Waves with Different Amplitudes

, 2019
In this study, the wave amplitude dependency on a ship advancing in regular head waves with different amplitudes is investigated by Experimental Fluid Dynamics (EFD) method. The thrust, towing force and 3DOF (Degree of Freedom) motions as well as the flow field around the stern of KVLCC2 (KRISO Very Large Crude-oil Carrier2) tanker model advancing at ...

ADDED RESISTANCE IN WAVES OF INTACT AND DAMAGED SHIP IN THE ADRIATIC SEA

Brodogradnja, 2015
In this paper the ship added resistance in regular head waves and at different sea states in a certain frequency range at different forward speeds was calculated. Calculations were conducted using hydrodynamic software.
