Abstract
A self-propelling device for burying and digging up subsea conduits laid on beds of an incoherent material. The device has: PA1 disintegrating members using high pressure water jets to create a slurry of material, PA1 digging members having suction members which draw the suspension prepared by the disintegrating members, thus leaving a trench behind, and PA1 displacement members for moving the device on the seabed astride the conduit.
