What are Norman pins used for?

Norman pins are specifically designed to limit the sweep of a hawser across the deck. In maritime and underwater operations, controlling the movement of equipment and lines is crucial for safety and operational efficiency. The hawser, which is a heavy rope or cable used for mooring or towing, can pose hazards if it sweeps across the deck uncontrollably. By effectively using Norman pins, operators can secure the hawser in a designated position, preventing it from moving excessively and reducing the risk of accidents or entanglements on board. This is particularly important in dynamic environments where the deck may be busy with personnel and equipment.

The other options involve various tasks related to maritime operations, but they do not accurately define the specific role of Norman pins in regulating the movement of hawsers.
