The Max Waldeck was the world's first icebreaker with a Thyssen-Waas-Bug .
history
The Max Waldeck was built in 1966 by the Hamburg Norderwerft on behalf of the Waterways and Shipping Directorate in Kiel . The shipyard test drive took place on October 17, 1967. The purpose of the ship was the icebreaking service on the Kiel Canal and magnetism investigations in connection with the shipping lanes of the North and Baltic Seas, which were still partly mined at the time . The ship was named after the then 88-year-old Max Waldeck - until 1942 he was head of the department for maritime issues of the Reich Ministry of Transport .
In 1981 the ship was fitted with a Thyssen-Waas bow as part of a research project by the North Sea Works in Emden . This conversion was carried out at the expense and risk of the shipyard carrying out the work. If the bow had not met the requirements placed on it, the Nordseewerke would have been obliged to restore the old condition. The shape of the fore section is slightly wider than the main bulkhead of the vehicle and resembles a box with defined edges in the underwater area. This principle ensures that when the bow pushes against the ice to be broken, clods break out of the ice under the weight of the icebreaker, split into two pieces by the center edge and under the ship by blowing compressed air sideways under the ice be pushed. The ice gets out of the area of the propeller, which minimizes the risk of damage. In March 1981, the first test drive into Finnish waters took place. The tests showed that the Thyssen-Waas-Bug saves a good 60 percent in drive power compared to conventional icebreakers.
At the end of the tests, the Max Waldeck was badly damaged by a fire on board on March 31, 1981. In April the ship was towed back to the North Sea Works, where it was repaired. After about a year, the Max Waldeck was back in service and further tests in the ice followed. For many years the icebreaker lay in the Rendsburg Saatsee and waited for operations in the ice. In 2006 the icebreaker was decommissioned and shortly afterwards sold for 200,000 euros. Since June 2011, the ship was as Anschutz listed for a hamburger company. In April 2016, the Dutch company Van der Kamp Shipsales took over the ship, the whereabouts are unknown.
Technical data and equipment
The ship is powered by diesel-electric technology . For electricity generation were three MTU / Maybach - diesel engines each with 855 kW power : installed (type ND 655). Three Klöckner-Humboldt-Deutz engines are available as auxiliary diesel engines (2 × F6M716 with 110 kW each, 1 × A4m514 with 31 kW). Propulsion takes place via a locking propeller, which was retrofitted with a Kort nozzle in 1982 . The ship initially reached 14 knots , with the Thyssen Waas bow still 12 knots.
The ship can be used as a tug . For this it is equipped with a tow winch with 38 t bollard pull . Together with the towing bracket, the ship is 55.34 meters long, without the towing bracket it is 50.87 meters.
On the aft deck there is a deck crane with a 10 meter jib length that can lift 3 t.
The ship is equipped with 15 chambers that can accommodate 28 people.
