The Walther Herwig III is the largest of the three German fishery research vessels . The shipowner is the Federal Ministry of Food and Agriculture (BMEL). It is managed by the Federal Agency for Agriculture and Food (BLE).

The ship is primarily available to the Johann Heinrich von Thünen Institute . It is used for research trips in the northern North Atlantic , the North Sea and the Baltic Sea . The ship's home port is Bremerhaven .

history

The ship was under the 1992/1993 hull number 167 of the consortium fisheries research vessel in Berne , a merger of the two at that time to the Hegemann Group owned shipyards Peene Werft in Wolgast and Roland shipyard in Berne, built. The keel was laid on April 29, the launch on December 28, 1992. The ship was completed in December 1993 and delivered to the then Federal Ministry of Food, Agriculture and Forests. The ship, which was christened and put into service on December 16, was available to the then Federal Research Institute for Fisheries for research purposes. It was managed by what was then the Federal Office for Food and Forestry. The ship is named after Walther Herwig , the founder of German deep-sea fishing.

Technology and equipment

View of the working deck

The ship is powered by diesel-electric technology . As a driving motor a functioning electric motor of the LDW settlement GmbH (GC 71.10) with 1,350  kW power , of a variable pitch propeller acts. The ship can thus reach a speed of 13  knots . A six - cylinder four - stroke diesel engine of the type Krupp-MaK 6M453C with an output of 1800 kW was installed as the main engine.

In the bow there is a transverse thruster control system with an output of 1000 kW.

Two main generators with 1450  kVA or 1100 kVA apparent power and an emergency generator with 350 kVA apparent power are available for the power supply on board . The ship is also equipped with a wave generator with 2200 kVA apparent power.

On board there is space for 21 crew members who are accommodated in individual chambers. Eight single and four double chambers are available for twelve scientists, so that there are still four reserve places. Seven laboratories were set up for research purposes , including a universal, fish, wet and chemical laboratory.

There are no holds for catches. Instead, there is a tunnel freezer on board (capacity: 1000 kg / 24 hours) and two deep-freeze rooms for storing scientific samples.

The fishing technical equipment consists of two trawl warps wind with 3000 m trawling cable and 165  kN tensile force . For the safety net , a net is haspel present. There are also two hydrographic winches with a pulling force of 30 kN each.

There is a stern boom at the stern of the ship . In the deck area two deck cranes are installed, one on the starboard -Boots deck with 3.5 t capacity of 12 m and a display on the network platform with 2.5 t capacity at 9 m range.

The hull of the ship is reinforced with ice ( ice class E2).

replacement

As a replacement for the Walther Herwig III , the new construction of a seaworthy and multidisciplinary fisheries research vessel was signed on March 22, 2017. The contractor is the Damen Shipyards Group , which is due to deliver the ship in 2023.
