自卸砂船设计稳性缺陷分析及解决方法

Analysis and Solution of Designing Stability Defect of Dump Sand Ship

自卸砂船是内河中常见的一种船型,由于装卸效率高、对码头及岸线适应性强、经济效益好,近年来得到了大力发展。但由于设计阶段对货物的重量重心、散货滑移量、侧受风面积计算不准确,导致稳性衡准偏离安全,存在设计缺陷。本文通过分析传统设计方法存在的缺陷,找出安全事故发生的真实原因,并给出改善此类船舶稳性的可行方法。

Sand dump ship is a common type of ship in inland river. It has been developed vigorously in recent years because of its high loading and unloading efficiency, strong adaptability to wharf and shoreline, and good economic benefits. However, due to the inaccurate calculation of the weight, the gravity center, the bulk cargo slip and the side wind area in the design stage, the stability criterion deviates from safety and there are design defects. By analyzing the shortcomings of traditional design methods, this paper finds out the real causes of safety accidents and gives feasible methods to improve ship stability.
