Stone dumping vessel having symmetrical stone compartments

摘要

A stone dumping vessel 1, having symmetrical stone compartments 12 and including a hull 10, a stone conveying unit 20, and an oblique fallpipe unit 30. The hull has a control cabin 11. A cannula compensating device 31 of the oblique fallpipe unit is disposed on a side of the hull and connected with a fallpipe. Two sides of the control cabin are symmetrically provided with the stone compartments and dynamic positioning (DP) system cabins 14, respectively. The stone compartments are operated independently for automatically unloading stones to the stone conveying unit disposed at a lower center thereof. The stones are conveyed by independent conveyor systems disposed at the left and right of the control cabin to the fallpipe. The dynamic positioning (DP) system cabins and the cannula compensating device are adapted to position the hull and the fallpipe respectively so that the stone dumping vessel having symmetrical stone compartments can achieve high accuracy of stone dumping.
