On Monday, 31st July 2017, Uljanik Shipyard has successfully carried out the installation of the cutter ladder for Newbuilding 500 - a self-propelled cutter suction dredger that Uljanik is constructing for their longtime partner JDN Group.

The cutter ladder is one of the most complex parts of this ship. It consists of 7 sections, the thickness of the material at certain points exceeding 150 mm, and its trunnion, tilting and sea fastening points require on site machining to achieve exact measurement. Cutter ladder is equipped with 2 main lines, dredge pump line and cutter line. The underwater dredge pump of 8500 kW is powered by 2 el. motors of 4250 kW over the gearbox and is forming the dredge pump line. Two additional el. motors with a gearbox of almost 300 ton which are connected to the cutter head over the shafts are forming the cutter line which is used for dredge the sea soil.
