Hamburg Port Authority (HPA) has taken the new state of the art ?700,000 sounding boat Deepenschriewer 1V into service.
Hamburg Port Authority (HPA) has taken the new state of the art ?700,000 sounding boat Deepenschriewer 1V into service for hydrographic sounding and measurement work within the Elbe River seaport.
Described as "extra small and extra slow", the boat has been designed specifically for the sounding and measurement of shallow and narrow waterways within the port. Billions of Euros are being spent there by the HPA and terminal operators on major infrastructural terminal, access and other developments to meet the demands of new generation container ships.
Drawing just 80cms, the 11.59m long and 3.7m wide Deepenschriever (literally "depth measurer") can go nearly everywhere in the port and, importantly, provide reliable information for other ships and report where and when dredging is required. Only three metres high and displacing just 11 tons, it can also pass under most of the port"s bridges without problem.
Built by specialist small ship and workboat builder Hermann Barthel in the east German Elbe town of Durban, the fixed propeller Deepenschriver 1V is the smallest boat in Hamburg"s water sounding and measurement fleet.
Driven by a 272kW Iveco diesel of Type NEF450, it is capable of 15 knots if required but officials said "slow ahead" was the general maxim for exact measurement work. The boat"s ZF80A reduction gearbox system has a hydraulic mechanism to allow slow speed and exact manoeuvring and positioning. A 6kW bow thruster is installed to increase manoeuverability. A rear view camera is also installed. A Fischer Panda 18kVA on board diesel generator feeds on-board electric systems.
The heart of Deeperschriever 1V however is its multibeam SeaBat 7101 echo sounding system from RESON, which is also described as state of the art.
The HPA said that of the ?700,000 cost of the new boat, ?300,000 had been spent on its modern sonar and measurement equipment. "It"s a good investment in the safety of the port", the authority said.
