Design philosophy of the Contender
For the Dutch firm ABEKO Marine, Conoship International provided the conversion design and calculations of the former 3,200 tdw general cargo vessel into a state-of-the-art Trailing Hopper Suction Dredger. Our activities comprised the re-design of the general arrangement of the vessel to a dredger, hull form modifications, stability and watertight integrity.
To obtain more deadweight and to improve the vessels stability, two sponsoons were fitted to the full midship length of the hull, enlarging the bread from 12.50 to 16.00 m. The cargo hold was re-designed into a hopper with bottom doors. Discharging of the hopper can also occur by means of a rain bowing system, a floating pipeline or by an excavator. The maneuverability of the vessel was enhanced with four thrusters which made the vessel capable for operation in a narrow areas.

A naval architect acts as the critical independent technical bridge between the shipowner, the shipyard, and the Classification societies. By delivering a comprehensive, class-approved detailed engineering package. This can include structural analysis, construction drawings, and updated stability data. We eliminate project uncertainties , protect the owner from costly shipyard delays, and streamline the final certification process.
