大型矿砂船舱盖适应大舱口的设计

Design of Hatch Cover to Fit Very Large Ore Carrier

在分析大型矿砂船大舱口理论变形的基础上,研究舱盖与舱口之间的相对变形。改进舱盖和舱口围连接装置的设计,使舱盖在船舶靠港和航行过程中均能适应舱口的大变形特性。

The relative deformations between the hatch cover and the hatch opening are studied based on the analysis of theoretical deformations of large hatch opening of large ore carriers,so as to improve the design of hatch covers and the hatch coaming connection device,and to make the hatch covers adaptable to the large deformations under both berthing and sailing conditions.
