GENERAL DESCRIPTION:
The dredger fleet of Royal Boskalis Westminster recently was complemented with TSHD ‘Shoalway’. The dredger combines a relative shallow draught with flexible dredging capabilities. Discharge of hopper loads can be achieved through bottom doors or a bow coupling. The bottom doors are integrated in the double bottom structure. A high maneuverability is effected by two rudder propellers. Contractor and designer worked closely together. Already from start of design keywords such as highest operational flexibility in various dredging environments as well as ‘state of the art’ technology played a significant role.
