2 loading towers with 360 degree rotation for loading and distributing the dredge material into hold. Owners advise an average of 4 hours to fill the hold.
Discharging methodology: at present discharge is carried out by shore cranes.
Note: until 2022 the dredger was fitted with excavator Hitachi ZX650LC-3, mounted on rails. The conveyor belt (still in place), running on the SB side along the length of the hold, was loaded via a series of mini hoppers. The excavator has been removed, as have the hoppers. This system, however, could be re-installed/re-activated by buyers, if required. An excavator, without undercarriage, could be mounted on the rails (still in place) so it could travel down the hopper. The conveyor boom for shore discharge is still in place but the whole conveyor system would need to be overhauled.
Accommodation: 8 (single berths).
