PREPARATION OF TOWING OF ICEBERG AND PROTECTIVE SKIRT DEVELOPING AROUND ICEBERG

摘要

The skirt comprises a string of floating posts (20, 22) interconnected by panels (12) of flexible sheet material which are suspended in a vertical plane between each pair of adjacent posts. The posts comprise an underwater buoyancy chamber (24) of large diameter and a small diameter pole (26) projecting up out of the water therefrom. The skirt is folded in a zig-zag manner between a leading group I of hinge posts A, C, E and a trailing group II of posts B, D, F. The posts of the two groups are fastened together as are pairs of corresponding intermediate posts (22) of the innermost pair of stretches of skirt between the two groups. The length of the folded skirt may be in the order of several hundred meters, whereby a length of skirt sufficient to protect a tabular iceberg can be handled as a single unit during towing from its assembly point in sheltered waters to an iceberg and during deployment around the iceberg.
