Although many months may be needed for construction crews to restore the fuse plug and channel after such an operation, the total damage and cost to repair is less than if the main water-retaining structures had been overtopped.

The SZB project includes a 6.7 km-long (4.2 mi) immersed tube which also will be the world's widest immersed tube, carrying eight traffic lanes. [11] Prior to the completion of the Marmaray and HZMB tunnels, the Transbay Tube in San Francisco Bay, completed in 1969, was the world's deepest and longest immersed tube, at 41 metres (135 ft) below ...

They are used for transporting solid objects, as opposed to conventional pipelines which transport fluids.
A small boat stuffing box comprising an adjusting nut, a locking nut and a sleeve. On a boat having an inboard motor that turns a shaft attached to an external propeller, the shaft passes through a stuffing box, also called a "packing box" or "stern gland" in this application.
