Bilge keel design for the traditional fishing boats of Indonesia's East Java

International Journal of Naval Architecture and Ocean Engineering, 2019
Seakeeping, especially for the roll motions, is of critical importance to the safe operation of fishing boats in Indonesia. In this study, a traditional East Java Fishing Boat (EJFB) has been analysed in terms of its seakeeping performance.

CFD computation of ship motions and added resistance for a high speed trimaran in regular head waves

International Journal of Naval Architecture and Ocean Engineering, 2011
Some research work on CFD computation of ship motions and added resistance in waves for a high speed trimaran is carried out in this paper. The governing equations, Reynolds Averaged Navier-Stokes and continuity equations are discretized by finite volume

Development of the Seakeeping Performance Evaluation System Built-On-Ship (1)-Establishment of the Relative Dangerousness D/B for Factors on Seakeeping Performance-

Journal of Korean navigation and port research, 2004
The final goal of this research is to establish the relative dangerousness D/B for factors on seakeeping performance. This D/B is, essential to develope the seakeeping performance evaluation system built-on-ship. The system is composed of the apparatus for measuring a vertical acceleration to be generated by the ship`s motions, computer for calculating

A comprehensive study on ship motion and load responses in short-crested irregular waves

International Journal of Naval Architecture and Ocean Engineering, 2019
Wave-induced ship motion and load responses are usually investigated on the assumption that the incident waves are long-crested. The realistic sea waves are however short-crested irregular waves.

EXPERIMENTAL STUDY OF TWO LARGE-SCALE MODELS’ SEAKEEPING PERFORMANCE IN COASTAL WAVES

Brodogradnja, 2015
Actual sea waves and vessel motion are an unsteady nonlinear random process. The currently adopted test to simulate wave impact of vessel models in tank can't fully reveal the impact of real sea waves on vessel swing motion.
