基于AWQA的LNG浮式转接驳真空吸附装置吸附力模拟计算

Simulation Calculation of Adsorption Force of LNG Floating Transfer Vacuum Adsorption Device Based on AWQA

针对LNG浮式转接驳与3万m^(3)LNG运输船进行传输作业时,转接驳使用真空吸附装置与LNG运输船系泊,由于缺乏真空吸附装置的连接参数无法直接计算二者间各方向上的最大作用力的问题,为保证LNG传输过程的安全稳定,在AWQA中使用缆绳及护舷来模拟真空吸附装置,对传输过程中的系泊力进行计算,得出的LNG浮式转接驳真空吸附装置吸附力,计算结果对实船装置选型具有实际指导意义。

In the operation of transferring 30000 m^(3) LNG from the floating LNG transfer barge to the LNG carrier,the barge is mooring with the LNG carrier using a vacuum adsorption device.Due to the lack of connection parameters of the vacuum adsorption device,the maximum force in each direction between them cannot be calculated directly.In order to ensure the safety and stability of the LNG transfer process,the cables and fenders were used to simulate the vacuum adsorption device in AWQA,so as to calculate the mooring forces in the transfer process.The calculation results have practical guiding significance for the type selection of the actual vessel device.
