船舶设计中干舷计算简论

Brief Introduction of Freeboard Calculation in Ship Design

简要介绍干舷在船舶设计中的重要性与必要性和干舷计算的依据，国际航行船舶干舷类型以及影响最小于舷的因素。分析各种因素对干舷计算的影响。通过实践经验总结出各种不同船型对应的不同类型十舷，并阐述散货船勘划木材载重线的必要性。通过典型实例分析影响干舷计算的因素，从而概括出同一船舶如何在不减少吃水的基础上满足最小干舷要求。

This article briefly introduced the necessity and importance of the freeboard calculation in the process of the ship design. And pointed out the relevant rule the freeboard calculation is based on. It gave a brief introduction on the freeboard type and the factors affecting on the freeboard calculation through a typical example. The paper illuminated the necessity of the timber freeboard for bulk carrier. And it summarized how to comply with the requirements of the minimum freeboard with the same summer draught.
