FIELD: offshore concretion development, particularly to transport concretions from base ship to transport one.
SUBSTANCE: device comprises conveyer means connected to transport ship and comprising service sump, mud collector and pump compartment. Suction dredge connected to service sump by suction pipeline is arranged in the pump compartment. The suction dredge is connected with L-shaped pipe performing complete rotation in horizontal plane by pressure pipeline. The L-shaped pipe is installed to supply hydromixture to inclined grizzly grate and to move dehydrated concretion from grizzly grate to transport ship hold. Inclined receiving grizzly grate for hydromixture to be extracted is installed over mud collector. Water pump to supply outboard water to service sump and to sprinkler over receiving grizzly grate is arranged in pump compartment.
EFFECT: increased efficiency of mud and excess water removal from concretion inside base ship before conveying thereof to transport one and provision of continuous concretion extraction operation.
