Research On Virtual Assembly And Craft Instructions Digitization Of The Marine Engine Room Equipment

Engine room is the most important part of the ship, which focuses on a large amount ofequipment, pipes, and its layout design need experienced designers to spend more time tocomplete. For engine room area are generally placed in smaller space within a large number ofequipment and a variety of pipes which diameter size should not be ignored, so designers need tothink carefully about how to get the best arrangement. The work of marine engine room’s layoutis mainly concentrated in the bottom, because about70%of the equipment is placed in this area,so a reasonable layout is of great significance to the normal operation of equipment. Also, whenthe ship needs to repair, the methods are often based on their experience, or they prepare therepair list and then give it to the company who undertake the repair business. The drawings ofthe ship are only used in the stage of shipbuilding, they didn’t play an important role inmaintenance and repair.The layout of the engine room is so complex that we can’t decide how to plan. According tothis problem, virtual assembly technology is used to assist in the planning work in this paper.Due to lack of effectiveness in the maintenance management, we also present a solution thatused craft instructions digitization technology in this paper. The research object of this paper isthe bottom platform of the marine engine room, we do the following work to achieve the abovefunctions:Firstly, established3D models of the marine engine room according to the actual needs inTribon, and then import them to3DS Max2009for models adjustment. After the adjustment wecould add lighting, texturing, rendering and baking process to models in later work. We begin tomake assembly animation after finished the above work.Secondly, take the oil-water separator which placed in the bottom platform of the marineengine room as an example to illustrate the four technical problems need to be considered in thevirtual assembly process. Then import the3D models which are completed adjusting in3DSMax2009to VR-Platform for script editing. At last, the VRP interface could be embedded in C#to design human-computer interaction by using VRP-OCX component. Then we could controlthe assembly process accurately by code. Also, we can use the same method to design thehuman-computer interaction interface for the whole bottom platform of engine room, and thenput two control interfaces together. Finally, we could export the2D CAD drawings of the pipes, hull plates and equipment fromTribon, then set up three folders for classification storage. In the same time, we create newAccess Database table to store the craft information. After completing data stored procedure wecould use the function of connecting database in the VRP to connect each model in the scenewith the corresponding database. It helps us to achieve the date interaction function betweencraft instructions database and virtual assembly process control system.The completed system plays a role in the process of engine room equipment’s layout andship’s maintenance. And the research work could provide us some suggestions to create newtype of ship’s maintenance and management system.
