What is a fallpipe vessel?
Fallpipe vessels are the most advanced, using an underwater pipe with an ROV at the end to deliver rock to the sea floor with high precision, even dumping rock underneath structures.
What is a rock discharge carrier?
Rock dumping vessels are a category of watercraft that exist for the purpose of dumping rocks on the seabed. They are able to transport and dump rocks of variable sizes. Side-discharging by means of crane is usually done in shallow waters, while fall pipes are more commonly used in deep-water rock-dumping operations.
What caused the rockness to capsize?
However, water in the two forward ruptured holds compromised an already unstable ship. The improperly loaded cargo was shifted to the starboard side in an avalanche fashion, capsizing the ship within four minutes (estimated by an observer) of the grounding.
What happened to the Rocknes?

What are rock dumping vessels?
Rock dumping vessels transport and dump rocks of various sizes for offshore and coastal protection applications. The dumping can be done with a large crane, but also through the concepts of side stone dumping vessels and flexible fallpipe vessels.
Boskalis fleet of fallpipe vessels consists of two dedicated self-propelled DP-2 vessels equipped with a flexible fallpipe which can be lowered into the water. Uniquely, the fallpipe vessel can position rock with extreme accuracy down to a depth of 1,500 meters.
How are rocks placed in a fallpipe?
Typically fallpipe vessels are used to install the rock in water depths up to 2000 meters. The rocks are dumped through a long and flexible fallpipe and a Remotely Operated Vehicle (ROV) makes sure the accurate dumping of the rocks. If playback doesn’t begin shortly, try restarting your device.
What is a side stone dumping vessel?
