According to CCS rule of "Guideless" for the Application of Steel Sandwich Panel Construction to Ship Structure", inner hull and outer plates of tanker are superseded by sandwich plate system. Laminate modeling method is compared with 3D substantiality model analyzation by using nonlinear numerical simulation. Simulation results show that it is effective to adopt laminate modeling method for SPS collision problems on microcomputer, which can meet the requirement of precision for general engineering problem. The crashworthiness of SPS side structures is compared with that of conventional double side structures of tanker, and comparative researches indicate that sandwich plate side structures can provide larger collision force, better energy absorbing capability and much larger crashworthiness index. Therefore, the advantage of crashworthiness by using the SPS side structures of tanker is validated. Source

Here, the structural responses of a Lazy-wave deepwater umbilical were obtained including configuration, distributions of effective tension and curvature with the static analysis. Meanwhile, the sensitivity analysis of the general layout parameters including length of buoyancy catenary, buoyancy factor, starting location of buoyancy catenary and top hang-off angle was performed and the influences of the general layout parameters on the structural response of the umbilical were analyzed. These study results provided a reference for Lazy-wave configuration design of deepwater umbilicals. ©, 2015, Chinese Vibration Engineering Society. All right reserved. Source

By analyzing Dapeng Sun LNG ship cargo handling system, established mathematical models of liquid cargo pumps and tanks, derived the relationship of the cargo pressure, temperature, liquid level changes over time in cargo handling operations. In the VISUAL BASIC 6.0 integrated programming environment, designed to simulate liquid cargo operating system graphical user interfaces, established the running logical relationship and simulated of the LNG liquid cargo handling process initially. Supplied an effectively way to train the crews and solved the lack of talent in liquid cargo transportation for our own country. Source
