When using spuds construction, after the dredger is towed to the starting point of the channeling, the tug-boat should be decelerated and stopped. After the ship’s speed is eliminated, put down the spuds and set the transverse anchor. It is strictly forbidden to put down the spuds while moving the dredger.
When using the anchoring rope transverse dredging method, the poop anchor should be thrown first according to the wind flow condition, or the cutter ladder should be placed down to the bottom of the water, and then other anchor rope should be thrown;
After anchoring, the ship should be repositioned and corrected to confirm that the cutter is at the starting position of the channeling.
