Abstract
Panels of cloth or sheet material are reeled out in parallel plane layers and joined in pairs along alternate edges to form a folded structure which can be deployed around at least a part of a tabular iceberg and then allowed to extend concertina-fashion to provide a protective jacket next to the flanks of the iceberg. The upper part of the skirt can be of more robust material in order to stand up to the action of waves and swell, while the submerged portion (deployed concertina-fashion) serves to keep warm water from coming in contact with the iceberg. The skirt is intended to protect icebergs being towed from antartic seas to the tropics.
