On the morning of 23 September 2020, the Marshall Islands registered refrigerated general cargo ship ICE ROSE collided with anti-submarine ship 311 KAZANETS of the Russian Navy in the Sound, Denmark. The collision happened as ICE ROSE and 311 KAZANETS were passing on crossing courses while navigating in a dense fog. Due to the restricted visibility, both ships’ navigation relied on instrumentation only. Neither of the ships identified the other ship until a few minutes before the collision, and neither ship managed to avoid the collision once the risk of collision was recognised.
