摘要
海外港口建设的海域中,显著的中长周期波浪给系泊船的稳定性带来一定影响.基于波浪周期的变化开展系泊船水动力响应的数值模拟研究,并考虑船舶在系泊过程中可能遇到的不同装载状态和不同系泊布置情况.利用系泊分析模型MIKE21 Maritime进行验证和分析.结果表明,系泊船的水动力响应主要受到波浪周期的影响,特别是纵荡和横荡运动;横荡运动受系泊布置方式的影响较为明显,横摇运动受装载状态的影响最为明显;相较其他缆绳而言,系泊船的横缆系缆力对入射波浪谱峰周期的变化最为敏感.
Abstract
The stability of moored ships is affected by the significant medium-long period waves in the sea area where overseas ports are constructed.We carry out a numerical simulation study on the hydrodynamic response of moored ships based on the change of wave periods,and consider different loading states and different mooring arrangements that may be encountered by the ship during the mooring process.Then we carry out the validation and analysis work using the mooring analysis model MIKE21 Maritime.The results show that the hydrodynamic response of the moored ship is mainly affected by the wave period,especially the surge and sway motions.The sway motion is more obviously affected by the mooring arrangement,and the roll motion is most obviously affected by the loading state.The breast line force of moored ship is the most sensitive to changes in incident wave periods compared to the other lines.
