Dredger Design Features
The dredger consists of the following components, namely:
• central pontoon with two side pontoons;
• dredge pump pontoon;
• suction pipeline and dredge head pontoon;
• control cabin.
The dredger is built in the Trimaran design. Dredge pump and jet pump are installed in a separate pump room. Suction pipe is located below the waterline for the sake of trouble-free start of the dredger. The dredger size is designed to be transportable.
Electric equipment as well as pumps are located at one pontoon to avoid necessity to assemble and disassemble for transportation. The pontoons are sized to facilitate the transportation of the dredger and at the same time the vessel floats steadily on the water and better deals with the waves. To ensure the best floating position the ballast tanks are built into the front pontoons. For technical maintenance the ballast is removed and the depth of dredger submersion decreases. All the surfaces are sand blasted and are covered with a Wilkens coating system. The deck is covered with anti-slip coating. The railings, roller block on the front pontoons and the connection bars behind and under the control cabin are hot-dip galvanized. The dredger is equipped with Aurum dredge pump of APF 350 type. This is a horizontal pump installed on a rigid foundation on the main pontoon.
The control cabin is fitted with a modern and comfortable arm-chair for the operator. Control equipment and sensors are installed in the elbows of the operator chair. Moreover, there is a screen for programming and monitoring of the automatic mode of the dredger operation in the control cabin.
The following data are displayed on the screen:
• suction pipe position,
• dredge pump speed,
• discharge pressure,
• failures messages,
• speed of material pumping,
• operating condition of the sorting station conveyor (if available)
• operating condition of the booster station (if available).
