Abstract: With the further development of the Arctic and Antarctica, the deployment and recovery of the anchorage observation system has become the normal operation content of the scientific research icebreakers.In the process of polar exploration, the placement of anchorage system is relatively simple, but the recovery operation is often affected by weather, sea conditions, floating ice, etc., which makes it impossible to recover the anchorage system successfully. In this paper, the new technical scheme of anchorage system recovery in floating ice area is discussed, and the suggestions and measures of anchorage system recovery in north and south polar areas are put forward, which can be used for reference in the future placement and recovery of polar anchorage system.
