Oil Tanker Simulation System Based on NT Platform JIN Zheng-tao,CHEN Hui,SHANG Qian-ming (Simulation and Control Center, Wuhan University of Technology, Wuhan 430063,China)An oil tanker simulation system was developed based on NT platform. It established visual three-dimensional models to replace real equipments, trained in different interfaces of the system. Analyzed the framework and explained the main different modules. The emphases were interface switch, ActiveX controls, DLL and shared memory. The results showed that the system met the demand of tanker workers with or without operation experience.simulation; ActiveX control; share memory
