General characteristica. Self-propelled trailing suction hopper dredger with the functions of hopper self-emptying, bow-ejection and bow-blowing for pumping ashore.b. It is a single steel deck ship with bulbous bow and twin tail fin. The wheel house is located on the top of poop.c. Two engines, twin propellers and twin rudders with electrically driven bow thruster.d. Dredging in great costal area and navigation in unrestricted area.e. Soil loading capacity: 8800 tf. Max. dredging depth: 30mg. Two trailing suction pipes with three lifting pointsh. Full loaded navigation speed: 12kn,  Dredging speed (two suction pipes dredge, converse water current speed 4kn): 2-2.5kn.i. Complement: 36Pj. Power of main engine: 3088KWX2k. 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.  The design, building, material and equipments used for this vessel all satisfy the requirement of CCS towards unrestricted navigation area. Main equipments employed in the vessel can provide global service. This dredger can be used internationally for sea-route dredging and ocean filling project. The design, building and equipments used in the vessel are to achieve the safety and reliability of the utilization of the vessel so that acquire high return for owner.This new building ship is planned to be delivered in November of 2008.Welcom to contact us.
