Opis:
This paper aims to the computing model of quantitative elements in crossing situation based on the separating of different states about vessel’s meeting to study the automatic collision-avoiding plan of given way vessel in crossing situation. Following results are proved by simulations: The accuracy of hydrodynamic model is enough for studying and application for automatic collision-avoiding; computing model of quantitative elements by method of bisection is rapidly and reliably convergent during computing. The whole meeting process can be separated to several stages according to the quantitative elements in crossing situation. Different initial collision avoiding measures of given-way vessel in different stages produced as per rules and ordinary practice of seaman.

Opis:
The January 2009 issue of the Journal of Navigation included a paper (John Wilde Crosbie 2009) entitled, “Revisiting the lessons of the early steering and sailing rules for an e-navigation age.” Following a description of the development of the COLREGS from the early 19th century, he concluded that the current steering and sailing rules should be replaced by a single rule more suited to modern conditions. This might take the form of rule stating that a vessel taking action to avoid collision should not pass ahead of the other vessel. Such a rule would require a radical change in the philosophy of collision avoidance at sea, and evidence is required that it would be both effective and acceptable by mariners. Radar simulator experiments, conducted by the author some years ago, in another context, suggest that this might be the case. An analysis of the experimental results and some conclusions are reported in this paper. The author believes that further trials, specifically designed to test the Crosbie proposals, would be desirable.

Opis:
Many ship collisions have been caused by a navigator’s error in the situation awareness (SA) of the navigator. In congested sea areas, navigators classify ships on the basis of different priority levels. For safety measures against ship collision, it is imperative for navigators to recognize the ships with high priority levels. In previous study, navigators’ SA was measured in a ship maneuvering simulator using the Situation Awareness Global Assessment Technique (SAGAT). From the results of the previous study, we proposed a new risk category, named as “attention area,” that covers ships with high priority level in the SA of navigators. However, the extent of data for navigators’ SA was limited. Therefore, the purpose of this study is to confirm the validity of the category using additional data of navigators SA. In this study, the validity of the proposed category was confirmed, and a limit line surrounding ships with high priority levels was identified. In addition, it was evident that the category was able to detect ships with high priority level around the time when the collision avoidance was performed.
