Research On The Visual System Of Semi-submersible Heavy Lift Vessel Handling Simulator

With the global oil consumption increasing and oil price rushing the summit, investment of deep-sea oil and gas projects is rising,so that transportation demand on related equipments is rapidly grow,such as drilling platforms,oil and gas production equipments.It is popular for professional long-distance maritime transport of heavy sets of large vessels in shipping market.In shipping market,it lacks the global professional vessels,specially professional technological workers.As a result of lacking training platform,seamen may operate misplay during the manipulating process of semi-submersible heavy lift,causing serious results.For the studying and training demand of semi-submersible vessel operators,it is necessary to research semi-submersible simulation system in the navigation simulator circumstance,the visual system of semi-submersible heavy lift vessel is an important part of the whole system.Basing on the shipping statics,the thesis realized the visualization of the semi-submersible heavy lift vessel handling simulator under the Visual C++ and OpenGVS visualization development environment.The main works of the article could be summarized as the following four points:1.Basing on the shipping statics,the simulation software integrated and ament the existing stability module,and realized dynamic stability calculation during the process of semi-submersible heavy lift vessel loading heavy cargo2.In terms of heavy cargo loading mode,the thesis studied calculating method about loading heavy cargo with rolling and submersible by using semi-submersible heavy lift vessels.By analysis of the stability data,the thesis also drew up the corresponding adjustment of ballast water3.By making use of OpenGVS visualization development environment,the thesis exploited the visualization of semi-submersible heavy lift vessel handling simulator. The thesis realized the visual transfer and track,and mounted three cameras in order to display the semi-submersible heavy lift vessel state from the navigation cabin,cargo deck and outside of it. 4.The thesis realized all kinds of status on vessel by reading the stability module parameters,such as head draft,stem draft,mean draft and the ship model parameters,such as course and rotation of turning of ship heading.
