Anchorage point for iceberg tow - has thin walled metal pegs on anchor chain and seated in ice by pressure or heating

摘要

The anchorage point for the icebergy tow has thin walled metal inserts (9) which are driven into the ice and whose upper ends are fitted to a flat plate (10) supporting the tow and spreading the towing force. The inserts are driven into the iceberg either by a large mass on the plate or by electric heating elements in the tips of the inserts. The molten ice freezes again after the inserts are driven in. The system allows the icebergs to the towed to other parts of the world as a fresh water supply.
