Simulation Research Of Slippage Shipment Process Of The Large Structure

Slippage shipment technology of the large structure is key technology of marine petroleum engineering, replace traditional floating crane, pull large structure including platform chunking and jacket to barge across guide way with winch, during process adjust water volume of water chamber of barge in order to make buoyant and stability of barge be in range operation needed according to real-time monitor variation of load and tide. At the present studying of correlation technique and control mechanism isn't thorough. It was burning question that how to control operation of slippage shipment reasonably and improve reliable and efficient.According to character of slippage shipment of the large structure, analyze load status of barge,variation of buoyant and stability, tide ,another correlative factor's influence during different stage of slippage shipment. Through studying of modeling of ballast water adjustment of slippage shipment process and key technology, combining with visualization technology to build simulation platform, implement visualization simulation of operation of slippage shipment .The main research of this paper can be include as follows:1. Through researching of slippkage shipment process of of the large structure,different operation style of slippkage shipment and correlative environment factors that influences slippage shipment, based on ship statics theory, analyze buoyant and stability of barge during slippage shipment .2. Based on analysis of load variance of slippage shipment process and ship statics theory build adjusting control model of ballast water . And through optimality analysis of adjust of ballast water during process of slippage shipment, build optimizing model.3. According to analyzing of slippage shipment operation process and working mechanism of system , use object-oriented development method to program computer simulation program, imitate dynamic variation of stability and buoyant,adjustment process of ballast water of barge.4. Using OpenGL to build visualization simulation environment of slippage shipment of the large structure, emerge temporal and spatial variation of every system distinctly during dynamic process of slippage shipment, implement visualization of simulation process of slippage shipment of the large structure.
