A planning model of ship equipment support system was proposed， which was systematization and complexity， on the basis of many years’ experience in the equipment support engineering. The planning layered structure and mapping relation of core problems were established， which factors were divided into three aspects， such as support demand， capacity-building， organization and implementation. The framework system of ship equipment technique support task， the demonstration model of ship life cycle maintenance structure， and the method of ship equipment maintenance design were built， which broke through the key techniques of ship equipment support system planning. This planning model could provide theoretical foundation for synchronizing supporting structure of ship equipment supporting system on the development stage of equipments， undertaking the technique support work orderly， and forming the support capacity fast.
