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

Power increase and propulsive characteristics in regular head waves of KVLCC2 using model tests

Ocean Engineering, 2020
Abstract This paper employs experimental methods to predict speed-power-rpm relationship along with resistance and propulsion characteristics in regular head waves with varying wave lengths and steepness ratios. The objective ship is KVLCC2. The resistance and self-propulsion tests in calm water and in waves have been conducted.

Analysis of added resistance and seakeeping responses in head sea conditions for low-speed full ships using URANS approach

International Journal of Naval Architecture and Ocean Engineering, 2017
The KVLCC2 and its modified hull form were investigated in regular head waves using Unsteady Reynolds Averaged Navier–Stokes (URANS) methods. The modified KVLCC2 (named KWP-bow KVLCC2) is designed for reducing wave reflection from the bow.
