Abstract: A stone dumping vessel having symmetrical stone compartments includes a hull, a stone conveying unit, and an oblique fallpipe unit. The hull has a control cabin. A cannula compensating device 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, 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.

Abstract: A stone dumping real time measuring system for a stone dumping vessel includes a boom. The boom is mounted to a control cabin of the stone dumping vessel and can extend outwardly from the control cabin to be located above a predetermined stone dumping position. A signal line hangs from the boom. A floater is connected to the other end of the signal line. The floater is provided with a positioning device, a surge compensator, and a depth sounder. The floater freely floats on the water through the separate design of the floater and the stone dumping vessel. The floater is directly positioned by the positioning device of the floater, and the surge compensator is able to correct a measurement error of the depth sounder to instantly report the stone dumping result and to improve the accuracy and precision of the stone real time measuring system.
