Abstract: A suction caisson system comprising a caisson body comprising an upper rim, a lower rim, and a weakened section positioned between the upper rim and the lower rim. The system further comprises a caisson cover constructed and arranged to detachably connect to the upper rim of the caisson body as well as a pump constructed and arranged to provide fluid to and from the interior of the caisson body. In the event the caisson body is impacted by an advancing ice keel, or other foreign object, the caisson body will be sheared at the weakened cross-section, thus protecting any subsea equipment positioned within the caisson body below the weakened section.
