DREDGER TSHD «BELOMORSKIY»

Twin screw, self-propelled trailing suction hopper dredger dragging suction pipes equipped with hydro-scourers, bow thruster.

Designation: Dredging job with carriage of ground in hold for unloading either by opening of 14 single bottom doors in row (seven doors portside and seven doors starboard side), or using self discharger (pumps) for deposition of pulp through the sludge line at the distance up to 700 meters with height of stack place up to 4 meters.

Allowed weather conditions: wind force up to 5 Beaufort scale with max height of wave 1,75 meters (pitching) or 1,25 meters (rolling).
