Royal IHC has been awarded the contract for the design and engineering of a 6,500yd3 (5,000md3) trailing suction hopper dredge (TSHD) for U.S. based Cashman Dredging & Marine Contracting.
With this order Royal IHC will deliver technological know-how in its design package which will result in one of the most state-of-the-art dredging vessels in the United States.
The tailor-made shallow draft TSHD design combines advanced technology with a high level of manoeuvrability. The diesel electric configuration of the dredge will enable optimal power utilization for the various types of dredging works, and the engines will comply with air pollution regulations EPA Tier IV and IMO Tier III. The design incorporates state-of-the-art dredge automation and high-efficient dredge equipment, increasing the efficiency of the dredging process.
The design includes two dredge pumps that enable large discharge distances when operated in series. Furthermore, it features two suction tubes enabling operation in most conditions by either using both tubes or just one in a strong current scenario.
The vessel’s shallow draft allows sailing close to shore, decreasing shore discharge distances. Additionally, two azimuth thrusters provide maximum manoeuvrability.
