Скачать или смотреть Giant Claws Emerge from the Sea: Clearing an Entire Shipping Channel with a Single Grab

This video documents a large grab crane vessel operating at sea, scooping up seabed sediment and loading it into the hold of a transport ship. The footage shows a giant orange grab slowly rising from underwater, its clamps tightly closed, filled with turbid sea sand and seawater. As the crane ascends, seawater continuously pours out from the gaps. Finally, the grab moves above the hatch and opens, dumping all the sediment into the hold. This operation is a typical dredging operation used to clear waterways, deepen harbor basins, and maintain safe water depths for ships entering and leaving the port. After removing seabed sediment with the grab, the waterway becomes deeper and smoother, preventing large ships from running aground or becoming restricted, and improving the port's throughput capacity. This dredging method is simple in structure, has a large grab capacity, and is highly adaptable. It is one of the most common dredging methods in port engineering. Through repeated grabbing, lifting, and dumping, the entire area is gradually treated to restore the waterway to its designed depth, improving the safety and efficiency of maritime traffic.
