MV Rocknes was a 166-metre (545 ft)-long rock discharge vessel that hit shallow water and suddenly capsized south of Bergen, Norway on 19 January 2004, killing 18 members of its 30-person crew.

The ship was on a long-term charter to Van Oord ACZ, an international contractor specializing in dredging, rock dumping, and offshore and coastal construction.

[2] Because of the density of the rock, the ship must include large void spaces located ahead of, astern of, and to either side of the cargo holds in the hull to provide sufficient stability.

They are designed with sloping sides and bottoms to allow them to be self-trimming and self-unloading via a conveyor belt running the length of the holds along the centerline of the ship at their lowest point.
