Another milestone has been reached on the road to the electrification of ship propulsion systems, both for Voith and the traditional HADAG. The first of three new type 2030 ferries for the Port of Hamburg have been commissioned in July 2024 and will be powered by an environmentally-friendly hybrid system comprised of two electric Voith Schneider Propellers (eVSPs).
Come rain, hail or shine, HADAG ships have been sailing through the Port of Hamburg and on the Elbe River since 1888, with operations spanning 365 days and around 330,000 nautical miles a year. In cooperation with the Hamburg Public Transport Association, HADAG operates all local ferry traffic on eight lines with 20 piers. In order to be optimally equipped for future economic and ecological challenges, sustainable fleet modernization measures are now in full swing.
The latest flagship in the fleet is the type 2030 hybrid ferry, which Voith has developed in conjunction with SET Schiffbau- u. Entwicklungsgesellschaft Tangermünde – a member company of the Heinrich Rönner Group – and Flensburg ship designers at naValue GmbH. What is particularly special about this application is that Voith was not only responsible for the propulsion technology but also for optimising the ship’s hull.
Aided by CFD simulations and automated optimisation methods, our R&D experts created over several hundreds individual hull design variants and calculated their respective energy efficiency levels, while strictly observing the customer’s exacting performance and consumption requirements. Numerous model tests were also carried out, which confirmed the result of our calculations Oliver Lenz, Sales Application Manager Marine at Voith
In addition to this result, further key data relating to the new ferry make for impressive reading. Courtesy of the optimised hull, the new ferry is larger than all of HADAG’s previous ferries, measuring 33 meters in length and eight meters in width. It has additional space for multi-functional areas and up to 250 passengers while running with significantly reduced energy requirements.
The necessary thrust and a maximum speed of up to 13 knots are provided by two 9X5/100 eVSPs – also newly developed – which are fitted with integrated permanent magnet electric motors from ELIN Motoren, a subsidiary of Voith Turbo. “Our smallest version to date of the gearless propulsion system expressly requested by the customer ensures the highest level of comfort on board at all times while significantly reducing energy requirements. Characterised by optimal manoeuvrability, the ELIN Motoren propulsion system has the distinction of providing a high level of safety, even in the often hectic and sometimes adverse conditions encountered in the Port of Hamburg,” say Lenz.
The experts from Voith also held several advance training sessions with HADAG captains, enabling them to familiarise themselves with the advantages of the electric Voith Schneider Propellers before the first of three hybrid ferries is commissioned.
