Abstract: This paper describes a design procedure for detachable platforms subjected to iceberg impact loads. The uncertainties associated with the iceberg environment have been dealt with in a statistical way and models for the exceedance of a given level of kinetic energy have been presented. A simple energy based model relating kinetic energy of an iceberg to the iceberg-structure impact force has been utilized to estimate global iceberg loads. Disconnection procedures have been related to a chosen (design) exceedance of kinetic energy so the expected number of detachments and false alarms can be calculated. The combination of iceberg load and other associated loads are touched upon, and finally a worked out example highlights the suggested design procedure.
