3100 TEU集装箱船总体线型的优化开发

Optimum Development of Overall Linear of 3 100 TEU Container Ship

针对3 100 TEU集装箱船总体技术要求,设计初步的船舶线型方案。在初始线型的基础上,为优化船舶各吃水下的阻力性能,对船舶直艏进行参数化建模和优化;利用半参数化方法基于船东营运需求,进行多轮优化;采用NAPA软件对总体性能进行全面的校核。对最终优化的线型进行船模试验验证,结果表明,航速达到优化目标要求。

According to the technical requirements of 3 100 TEU container ship,the preliminary ship alignment scheme is designed.On the basis of initial alignment,in order to optimize the drag performance of the ship under water,parametric modeling and optimization of the ship’s direct bow are carried out.Multi-round optimization is carried out based on the operation requirements of the shipowner by using semi-parametric method and overall performance is checked by using NAPA software.The final optimized linetype is validated by ship model test.The test results showed that the power/speed performance met the design target.
