Fallpipe vessel Rock Piper in Öresund
"A fallpipe vessel (FPV) is a self-propelled vessel that is equipped with a flexible fallpipe. The vessel's design allows the fallpipe to be lowered into the water beneath the vessel. Uniquely, the fallpipe vessel can position rock with extreme accuracy down to a depth of 1,500 meters. These vessels are highly suited to cover offshore cables and pipelines. They are also used to prepare the seabed for offshore structures and to put in scour protection for offshore wind turbines and platforms." (Ship company´s home page)
