How to realize highly efficient transmission and application of information in modern ship design,build,operation and maintenance is an effective approach to enhance the whole competitive ability for shipbuilding,and the grid technology have offered the effective guarantee for the shipping life cycle sharing information.Lots of information in various phases of shipping life cycle are analyzed and correlated,then the information model for each phase of shipping life cycle is constructed.A metadata model of XML used in the grid environment is given.A method using UID(Universal Identifier) is proposed to realize information transformation and mapping between various shipping life cycle phases.Then a framework of the ship lifecycle information system based on data grid and the integration framework inside an enterprise is established.At last,a prototype system of shipping lifecycle information sharing system based on Vega GOS grid platform is established,and several grid services of resource layers and applications layer are developed,in order to realize various powerful functions,such as unified resources visit,service dynamic discovery,resources dynamic gain and so on.
