Experimental analysis of the seakeeping performance of catamaran forms with bulbous bows

, 2018
This paper explores the effects of adding different forms of bulbous bows onto catamaran hulls and assesses the implications on the seakeeping performance. There has been a large body of work that assess’ the effect of wave wake wash and recently studies

Optimization of ship hull forms by changing CM and CB coefficients to obtain optimal seakeeping performance.

PLoS ONE
Ship design involves optimizing the hull in order to enhance safety, economic efficiency, and technical efficiency. Despite the long-term research on this problem and a number of significant conclusions, some of its content still needs to be improved. In

Full Scale Measurements on the Seakeeping Performance of a Plant Barge

Journal of the Society of Naval Architects of Japan, 1979
A 220m long and 45m wide square Plant Barge was towed for about three months from Japan to Brazil covering the distance of 13, 000 sea miles.During this towing, some of the items concering motions and strength of the abrge were measured for 40 minutes per day.

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.

Seakeeping performances of an AHTS ship

Annals of "Dunărea de Jos" University of Galaţi: Fascicle XI Shipbuilding, 2016
The importance of the evaluations of the response amplitude operators as well as of the accelerations in several points of interest on board of ship is directly linked to the index of operation of a floating structure. The higher the sea state to operate, the better the ship efficiency and operability.

The hydrodynamic and dynamic motion analysis of a damaged ship

, 2008
The hydrodynamic analysis and motion response of a damaged ship requires a novel generalisation of the methodsnormally applied to intact ships or other floating structures. Damaged ship statistics are used to provide likely damage scenarios.

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
