项目摘要

The main objective of this research work is development of a guidance system for safe navigation in rough seas. The research work was continued for three years and following five major results were obtained. According to the results, it can be conclude that the system developed here will contribute to safe navigation of ships.1.Making up the hardware : The weather condition, ship motions in waves and wave loads must be monitored by the system in order to support the safe navigation in rough weather. The requirements of the system are to be cost-effective and durable. The system developed here can satisfy those requirements by reducing the sensors.2.Development of system application program : The system application program was developed based on two kinds of prediction technique. The first one is the stochastic prediction technique called "short term prediction method" in the field of naval architecture and the second one is Baysian estimation method. Furthermore, introducing a suitable … More graphical user interface and a function of data storage as a data base, usefulness in the actual operation was improved.3.Feasibility tests : On board tests were carried out using the training ship Shioji-maru and the system application program was revised. According to the results, it was revealed mat the ship motions can not be analyzed as a non-stationary stochastic process in the actual ship operation. Therefore, the "short term prediction method should not be applied directly.4.Improvement of the estimation algorithm for directional wave spectra : For the reasons mentioned above, the estimation algorithm was modified. Introducing the TVVAR modeling and extending the Baysian estimation, it was shown mat non-stationary ship motions and time-varying wave spectrum can be analyzed.5.Maritime Broadband system : A new concept was proposed for merchant fleet management. The real-time remote monitoring system was developed using the Maritime Broadband system, which is a developing system of T.S.Shiojimaru using a communications satellite. Time consuming calculations for estimating wave spectra can be shifted to the shore side. Less
这项研究工作的主要目标是开发一种在惊涛骇浪中安全航行的导航系统。研究工作持续了三年,取得了以下五个主要成果。硬件组成:系统必须对天气状况、船舶在波浪中的运动和波浪载荷进行监测,以支持恶劣天气下的安全航行。该系统的要求是成本效益高和经久耐用。系统应用程序的开发:基于两种预测技术开发了系统应用程序。第一种是在造船领域被称为“短期预测法”的随机预测技术,第二种是贝叶斯估计法。此外,引入合适的…更多的图形用户界面和数据存储功能作为数据库,提高了在实际操作中的有用性。3.可行性试验:利用实船进行了实船试验,并对系统应用程序进行了修改。结果表明,在实际船舶运行中,船舶运动不能作为非平稳随机过程进行分析。因此,“短期预报法”不应直接适用。4.方向波谱估计算法的改进:基于上述原因,对估计算法进行了修改。通过引入TVVAR模型和扩展贝叶斯估计,可以分析船舶的非平稳运动和时变海浪频谱。5.海事宽带系统:提出了一种新的商船管理概念。实时远程监控系统是利用海上宽带系统开发的,该系统是T.S.Shiojimaru使用通信卫星开发的系统。用于估计海浪频谱的耗时计算可以转移到岸边。较少
