Abstract

Prediction of ship's response in real voyage condition is essential for efficient ship design. At sea, ships rarely voyage in head wave conditions, and mostly prefer oblique waves for lower resistance and better propulsion. This paper provides oblique wave simulation results for a container, tanker and bulk carrier using a commercial potential flow (PF) based solver, HydroSTAR. Although, PF codes have limitation regarding resistance prediction, they are well reliable in predicting ship motion in waves. The paper aims at providing a relative comparison of ship resistance and motion in different heading angles for three major ship models namely KCS, KVLCC2 and JBC. The paper should prove useful to shippers in case of weather routing or route selection for voyage.

基于势流解算器的船舶实际工况运动预测

船舶在实际航行条件下的响应预测是有效设计船舶的必要条件。在海上，船只很少在头浪条件下航行，大多数船只更喜欢斜浪，因为斜浪阻力更小，推进力更好。本文利用基于势流(PF)的商业求解器HydroSTAR对集装箱、油轮和散货船进行了斜波模拟。虽然PF规范在阻力预测方面存在一定的局限性，但对于预测船舶在波浪中的运动具有较好的可靠性。本文旨在对KCS、KVLCC2和JBC三种主要船型在不同航向角下的船舶阻力和运动进行相对比较。该文件应证明对托运人在天气路线或航次路线选择的情况下是有用的。

期刊介绍： Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance. Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
