There have been so many fatal accidents which may cause serious marine pollutions and the maneuverability standards is now under discussion at the IMO. Then it becomes important to predict maneuvering performance of ships at the initial design stage. In the present research a database system is investigated for such predictions.The databases of ships' particulars, hydrodynamic forces and maneuvering performance were built up and the procedures to estimate the relations among three databases have been developed. The database of maneuvering performance contains the sea trial results of about 760 ships and this is the most detailed one ever built.To investigate the relation between ships' principal particulars and maneuvering performance, both database were analyzed statistically and the empirical formulae were successfully found for turning abilities. However, it is difficult to find the clear relation between the principal particulars and the directional stabilities.An effort was also paid for finding the relations between the principal particulars and the hydrodynamic forces. It seems possible to estimate the rough relations between both databases. To estimate the maneuvering performance with enough accuracy, however, hull forms, especially of sterns must be taken into consideration. The concept of type ship is shown effective and it is pointed out that the combination of the database approach and theoretical procedures of hydrodynamic force estimations should be investigated.To evaluate the allowable limit of directional instability of ships under human control, simulator studies were widely carried out and the standard of this ability was finally proposed, taking account of the above limit and the possible level estimated from the database analysis. The proposal becomes the standard plan proposed by Japanese government for the IMO.

发生了许多致命事故，可能会导致严重的海洋污染，而IMO的可操作性标准正在讨论中。然后，重要的是要在初始设计阶段预测船舶的操纵性能。在本研究中，研究了数据库系统以进行此类预测。建立了船舶细节，流体力学力和操纵性能的数据库，并开发了三个数据库之间关系的程序。操纵性能的数据库包含大约760艘船的海上试验结果，这是有史以来最详细的船只。为了研究船只的主要细节和机动性能之间的关系，在统计上分析了两个数据库，并成功地发现了经验公式。但是，很难找到主要细节和方向稳定性之间的明确关系。还为寻找主要细节与流体动力力之间的关系而付出了努力。似乎可以估计两个数据库之间的粗糙关系。为了以足够的准确性估算机动性能，必须考虑船体形式，尤其是船尾的形式。表明船舶的概念有效，并指出，应研究数据库方法的组合和水动力估计的理论程序。为了评估人类控制下船舶的方向不稳定性的允许限制，将广泛进行模拟器研究，并提出了该能力的标准，最终提出了上述限制的限制，并考虑了上述级别的估计分析。该提案成为日本政府为IMO提出的标准计划。
