tshd INAI KENANGA

Inai Kiara is a Malaysian based dredging company which has the intention of becoming a major player in the dredging market. This intention is supported by a large investment program containing new building of various hoppers and cutter dredgers. For one of these vessels, a 32 000 m3 trailing suction hopper dredger, Vuyk was requested to assist:

After having developed the concept for the vessel, Vuyk performed the full basic design including dredging installation. Vuyk also made a finite element global hull strength analysis, including fatigue for the highly stressed locations. At last, Vuyk assisted the yard during the building stage with engineering coordination and further detailed design.
