Fallpipe vessels
Fallpipe vessels are able to deposit stone accurately at great depths. The crew use a remote-controlled system to position the end of the fallpipe just a few metres over the placement level. Then the stone is fed through the fallpipe while the vessel moves over the destination area. This method is frequently used in the oil and gas industry for leveling the seabed for pipelines or to provide pipelines with a protective layer of stone.
- DPFV 'Sandpiper'
Boskalis has two fallpipe vessels: the 'Seahorse' and the 'Sandpiper', with a new fallpipe vessel, Rockpiper, currently under construction. The 'Seahorse' can be fitted with an A-frame on the aft and a remote-controlled clamshell grab, enabling it to dredge at depths of up to 1,000 metres.
