#CMT# #/CMT# The installation is with a flexibly installed pile vehicle on a dredger vessel with a cutting head dredger. The (1), a ladder winch (9) and two side winches (2), an auxiliary pile (4) and a work pile (3) accommodated in a pile vehicle (6). At the outer end of the ladder is a cutting head (5), near to which are a suction pipe (10) and a pump (8). #CMT# : #/CMT# The vessel has a control cabin (7), a deck (12) and a pressure conduit (11), through which the dredged material is fed. The work pile ensures that a fixed point is formed around which the dredger can turn during dredging. When the work pile is in its end position, it has to be supported by the auxiliary pile (4), which is lowered so that it fixes the vessel in relation to the bottom, after which the work pile is raised and returend to its commencement position. After this, the work pile is fixed back in the bottom of the sea an the auxiliary pile is raised. #CMT#USE : #/CMT# On a dredger vessel with a flexibly installed pile vehicle and a cutting head dredger. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The first figure presents a side view and the second figure shows a plan view of the cutter dredger. 1 : Underwater ladder 2 : Side winches 3 : Work pile 4 : auxiliary pile 5 : Cutting head 6 : Pile vehicle 7 : Control cabin 8 : Pump 9 : Ladder winch 10 : Suction pipe 11 : Pressure conduit 12 : Deck. |
