Versatile duo complete Hamburg quartet
Two newbuildings designed mainly for ice-breaking but also capable of a range of other jobs have gone into service with the Port of Hamburg Authority (HPA) completing a €15.4 million four-ship renewal programme.
Built by Hitzler Werft in Lauenburg, the smaller of the two, the 23m long and 7m wide Hugo Lentz, draws 2.6m and is capable of breaking up solid ice up to 45cms thick in the port, on the River Elbe and in estuary waters. When not doing that, however, the €4.5 million newbuilding is being used as a tug with a bollard pull of about 9 tons and as a collection and transport boat. A removable bow can be attached for push operations.
Hugo Lentz has a1066kW ABC Type 6DZC engine of 750rpm operating over Reintjes gears and a Piening shaft and propeller to provide 10 knots. Its Type Heracles high-capacity rudder is from Becker Marine Systems and its auxiliary diesel is a John Deere Type 4045 of 61KVA. A Rexroth Marex OS111 system handles engine control and Alphatron has supplied many of the newbuild’s communications and navigational components, HPA reported.
The second, bigger, newbuilding is the 30m long, 8.5m wide Johannes Dalmann which draws 3.2m. Like its fellow newbuilding it can cope with solid ice up to 45cms thick and is for similar use around the port when not in service as an icebreaker.
Like Hugo Lentz, Johannes Dalmann was also built at Hitzler, is ice-classed E2 and has the same shaft and propeller, rudder, gearing, auxiliary engine, engine control and communications and navigation equipment. But the bigger boat is also of sterner stuff, with a bollard pull of 16.5 tons and an ABC Type 8 DZC engine of 1354kKW/720rpm providing about 12 knots. The extra clout and size is reflected in its €5.1 million cost.
HPA stressed the eco-qualities of the newbuildings. Both have low emission levels and are fitted with soot particle filters, water lubricated shaft plant and energy saving LED technology. They also use low-emission GTL fuel and are fitted with berth power connections.
The two latest newbuildings follow Christian Nehls and Johann Reinke which went into service a year ago. They are also from Hitzler and that yard’s Managingh Director Jürgen Freudenberg said they had “performed splendidly in daily service” since then. He also noted that building all four boats for HPA had provided his small shipyard with full employment for two years.
The earlier 18m long and 6.2m wide all-rounders cost around €3 million apiece. They are driven by MAN D2842LE412 main engines of 558kW and have John Deere 3029/40kVA auxiliary diesels. Drawing 2.2m, they have bollard pulls of some 7 tons and the same eco-friendly features as the later newbuildings.
