The diesel electric driven trailing suction hopper dredger ‘UKD Orca’ is one of Barkmeijer Shipyards’ deliveries. This sophisticated vessel was designed especially for port maintenance environments. Therefore, a dual suction dredging pipe was installed on portside as well starboard. To guarantee an excellent maneuvering flexibility, the vessels was equipped with two azimuth thrusters. Discharging of the hopper load is established by six bottom doors or by dredging pump via a shore connection portside or starboard.
