近海工程船主要尺度要素及线型设计特点与分析

本文针对当前市场所需的海洋辅助工程船舶,特别是拖轮、救助船及守护船的线型设计特点进行了分析与研究,提供了该类船型的主要尺度及有关参数的范围,可供设计人员参考.同时还对不同的艏部形状及有无导管的船模试验结果进行了分析比较,指出海洋辅助工程船舶应根据不同的功能和使用要求,采用不同的船型和推进形式,以最大限度提高船舶航行性能,并使其使用性能更趋合理.

Design Feature and Analysis of Principal Dimensions and Lines for Greater Coastal Service Engineering Ships

In this paper, the analysis and research of the lines design feature for ocean engineering ships, especially for tug, salvage and standby ship, that are in demand in recent market, are carried out. A selective range of some principal dimensions and relative parameters are provided for reference. Meanwhile, the analysis and comparison of ship model test results for different bow form and with or without duct indicate that ship type and propulsion form should be adopted according to different function and application demand of ocean engineering ship. Thus the seagoing performance may be improved furthest and the function of application more reasonable.
