The Type 711 Hiev-class crane ship was a class of floating cranes built for the Marinearsenal of the German Navy in Kiel and Wilhelmshaven
Development
[edit]Both cranes were built from 24 November 1960 for DM 4.3 million each under construction numbers 983 (Hiev) and 984 (Griep) at the Rheinwerft in Duisburg-Walsum and, after completion, relocated to their home ports via the inland waterways. The ship names are related to the task of the floating cranes and come from Low German: Hiev stands for “to lift” and Griep for “to grab”.
Design
[edit]The self-propelled floating cranes have a triple diesel-electric drive, each consisting of a MWM four-stroke 16-cylinder diesel engine with 442 kW, a three-phase generator with 700 kVA, a direct current drive motor with 350 kW and a Voith-Schneider propeller. One of the propellers is in the bow area, the other two in the stern area.
The double-link luffing jib crane is a MAN product. The lifting capacities are 100 t with a radius of 16.2 m and 50 t with a radius of 28.5 m and a maximum hook height of 35 m above the waterline.
A galley, living quarters for twelve people and workshops allow a sea mission of up to ten days.[1]
