Abstract Bridge alarms are a plausible way to reduce the ship collision probability by timely alerting the officer on watch of a conflict. However, there currently are no dedicated methods for alerting a stand-on ship to compensate the unawareness of or inactive response of a give-way ship to dangerous encounter situations. Therefore, this article proposes a collision alert system from the stand-on ship perspective to trigger the stand-on ship's involvement in the conflict elimination. The developed method quantifies the terms of the COLREGs regarding the stand-on ship's responsibility for conflict elimination. The conflict severity is divided into 9 classes based on the ship intention estimation, conflict evolution analysis and COLREGs scrutiny. These are linked with the 4 stages of the encounter process to helps stand-on ship clarify her action responsibilities as per the rules and classify the alert into four levels. The available maneuvering margin of the stand-on ship is considered to improve the accuracy of severity ranking. The results of several case studies in open water with good visibility indicate that the proposed method can support the stand-on ship to correctly understand the rules and to fulfil her duties.

符合 COLREG 标准的船舶碰撞警报系统，适用于站立式船舶

摘要 舰桥警报是一种通过及时向值班人员发出冲突警报来降低船舶碰撞概率的合理方式。然而，目前没有专门的方法来警告备用船以补偿让路船对危险遭遇情况的不知情或不积极响应。因此，本文从驻船角度提出碰撞预警系统，以触发驻船参与冲突消除。所开发的方法量化了 COLREG 中关于备用船消除冲突责任的条款。根据船舶意图估计、冲突演变分析和COLREGs审查，将冲突严重程度分为9个等级。这些与遭遇过程的 4 个阶段相关联，以帮助备用船舶按照规则明确其行动责任，并将警报分为四个级别。考虑到站立船的可用机动余量，以提高严重性等级的准确性。在能见度良好的开阔水域中的几个案例研究结果表明，所提出的方法可以支持站立船正确理解规则并履行其职责。
