Non-compliance with or misinterpretation of the International Regulations for Preventing Collisions at Sea (COLREGs) when assessing vessel encounters, and the lack of good communication between the vessels involved in a critical situation, are primary contributing factors in collisions. Vessels engaged in an encounter should be aware that they are part of the same scenario and situation, which can become critical. Sharing and contrasting their information about the encounter would help those responsible to take manoeuvring decisions in a consistent way. There are situations whose evaluation by the respective officers in charge of the navigational watch may diverge and lead to disagreements on the actions to be taken. If there is no proper inter-ship communication, a collision may result. This paper presents a proposal for safety communication implemented in a programmable system using common equipment (automatic identification system), and applies it to a case study of one such special situation, showing how it could help to reduce the risk of collision.

减少碰撞风险的船对船对话和协议

在评估船舶相遇时不遵守或误解《国际海上避碰规则》（COLREGs），以及在危急情况下船舶之间缺乏良好的沟通，是造成碰撞的主要因素。参与相遇的船只应该意识到它们是同一场景和情况的一部分，这可能变得至关重要。分享和对比他们关于遭遇的信息将有助于负责人以一致的方式做出机动决策。在某些情况下，负责航行值班的相应官员的评估可能会产生分歧，并导致对要采取的行动产生分歧。如果没有适当的船间通信，可能会导致碰撞。
