Vuyk scope of work
For Johann Bunte, Vuyk acted as consultant, giving advice about total layout and design. Furthermore, Vuyk made the designs for the cutter ladder, spud systems and the gantries. Also during the building stage a lightweight check was made and at the final stage an inclining test and all stability calculations were done.
