摘要： This invention relates to an adjustable apparatus for supporting a pipe, laid on a deep sea bed, at a depression in the sea bed. The apparatus according to the invention comprises an upper floating caisson provided with support legs and a lower support structure comprising guide tubes for said legs. The guide tubes are rigidly connected by cross members, which can be rotated from a rest position to a work position, in which they support the pipe.

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