There are many problems in the design of container guide rail, such as many structural sections that need to be installed on the rails, complicated layout of the connecting elbow plate in the different sections, the various types of connecting elbow plates and the complex weight statistics. A 3D design method is proposed for the container guide rail based on the Computer Aided Three-dimensional Lnteractive Application (CATIA) platform. The design efficiency is effectively improved by using the functions of CATIA such as the knowledge engineering, parametric design and unified assembly, enabling the more intelligent design and reducing the workload of the later modification.

This article focuses on the working efficiency of the scientific research ship with modular loads (mainly the research containers). The gain of modular loads to the work efficiency is analyzed through the comparison of the service situations of the scientific research ship with the different carrying capacities during one single voyage and the whole year. The ship borne research modular moving system is suggested to be equipped on the scientific research ship according to the increasing modularity.
