A NEW GENERATION OF SCHOTTEL-TRACTOR TUGS: JOHN AND HOLTENAU

After first listing and discussing the principal particulars and other main data of some of the many Schottel-tractor tugs operating in the port of Hamburg since 1972, this article describes two of the latest of this type to enter service, the John and the Holtenau. Being somewhat smaller generally and drawing less water than their predecessors, these new tugs can handle the coasters and shallower draught craft which use the smaller basins of the port. The John, built by Schiffswerft Johann Oelkers KG., Hamburg, for Neue Schleppdampfschiffs-Reederei Louis Meyer GmbH & Co., KG. Hamburg, has the following principal particulars:- Length 23.5m o.a., 22m b.p. Moulded beam 8.5m; Depth 3.6m; Draught 3.8m; power 2 x 540kW; propulsion 2 x Schottel-Rudder-propeller type SRP 350/350 with nozzle; bollard pull 21 tonnes; free-running speed 10.5 knots. The Holtenau, also built by the Johann Oelkers yard but for Kieler Verkehrs AG. for service in the Kiel Canal, is of similar design to the John but is somewhat larger and more powerful and has the following principal particulars:-- length 26.5m o.a., 25m b.p.; Moulded beam 8.5m; Depth 3.6m; Draught 3.98m; power 2 x 640 kW; propulsion 2 x Schottel-Rudderpropeller type SRP 503/505 with nozzle; bollard pull 26 t ; free-running speed 11.6 knots. Further details of these two tugs are given together with a general arrangement drawing of each.
