r. Dredging operation type:

  When the soil is dredged into the hopper, the soil

  1. it can be dumped by hopper bottom doors.

  2. by hopper self-emptying system to do bow-ejection for pumping ashore

  3. by hopper self-emptying system, connect pipeline by fast-connection ball joint to do bow-blowing for pumping ashore, the discharging distance is about 2000m. The vessel can use one or two suction pipes to dredge, and according to the reality, it can supply a head of 150m high-pressure flushing for any of the drag heads to improve the suction efficiency.
