The Key 12 , also known as Keyship 12 , is a type of semi-container ship from the Seebeck shipyard in Bremerhaven .
history
The ship type was designed in the 1970s following the construction of the very successful Seebeck 36L . The ships of the series are designed as universally usable semi-container ships for long voyages. In order to do justice to the changed framework conditions, the Key 12 was adapted for container transport and operation at higher speeds than its predecessor. The Key 12 type was continuously ordered by the Hamburg shipping company Claus-Peter Offen and built in six units. In addition, the Seebeck shipyard built two similar units with the same dimensions but different details for a shipping company from Cameroon, the Cam Ilomba and Cam Iroko, and in 1983/84 two further developed Key 12 latecomers for Offen.
The designation Key 12 is based on the symbolic Bremen key .
Technical details
The Key 12 ships have superstructures arranged aft and four holds , the rear three of which are closed by two centrally divided hatches and the front one by a single hatch. The hatch covers are of the MacGregor type . Different variants were used as their own loading gear; the first buildings each had two loading booms with a capacity of 25, 32 and 60 tons. The two more powerful pairs could work in coupled operation and then move 60 and 115 tons. Later buildings received three 25-tonne cranes, and later some 36-tonne cranes. The container capacity was increased during the series through optimizations from 576 TEU to 618 TEU.
The 162-meter-long Holstenbay with only two 36-tonne cranes, which was later delivered , had a container capacity of 1152 TEU, while the Savannah , which was built in the original dimensions and the same dimensions as the first six ships, had a capacity of 700 TEU. The Savannah was extended in 1991 and brought to the same dimensions as the Holstenbay .
The main engine on all ships was a MaK four-stroke diesel engine. Two prototypes were used, the Holstensailor was equipped with a MaK 16Mu 551 AK with an output of 7360 kW. The engine worked via a reduction gear on a fixed propeller. A MaK 8M 601 AK with an output of 6000 kW was installed in each of the following seven ships. In these units, the power was transmitted to a shaft generator and a controllable pitch propeller system . There was no bow thruster available to support the berthing and casting off maneuvers.
