Again HATLAPA in Uetersen have built a deep-sea towing winch size and capacity of which exceeds the one delivered in 2004 which had a weight of 56 tons.
The towing winch, weighing 84,5 tons, has been built in “waterfall” design, i.e. 2 rope drums arranged one above the other accommodate the towing ropes. The dynamic pull of the winch is 200 tons and the static holding load 320 tons.
The upper rope drum is belayed with a towing wire (76 mm diameter) of
1.200 m length. The lower drum having a towing wire of the same diameter but 1.600 m long.
The towing winch is driven by the “stepless drive” which has been developed and patented by HATLAPA. Frequency inverter controlled electric motors and corresponding controls allow stepless operation of the winch, otherwise known from hydraulic drives. Thus protective operation at very high rope speeds of up to 31 m/min. is guaranteed. Additionally, the winch is equipped with 2 cable lifters for a 76/127 mm stud-link chain.
The winch will be installed on a deep-sea tug which is presently being built by the Mützelfeldt Shipyard in Cuxhaven. The order was placed by Ferrostaal, Essen and Harms Bergung, Hamburg who will be operated this tug and which will be used for all kinds of deep-sea transport, offshore work, salvage and rescue in sea accidents. This deep-sea tug is the First of 4 tug boats being built in Germany completely.
In cooperation with Ferrostaal and Harms Bergung it was possible to arrange the transport from the port of Uetersen to the Mützelfeldt Shipyard in Cuxhaven.
