Spreestein

from Wikipedia, the free encyclopedia

The Spreestein (built in 1957) was a liner freighter of the Spreestein class of the North German Lloyd . She was the first German cargo ship with plastic lifeboats .

history

The Spreestein was built under the hull number 855 at the Bremer Vulkan and completed its test drive on May 20, 1957. Just a month later, the sister ship Siegstein with the hull number 856 followed. Both were with a length of 126 meters and a width of 16 meters with 4,900 BRT measured and had a load capacity of 6,725 dwt. A single-acting two-stroke diesel engine (BV / MAN ) with 6 cylinders of the type KZ 70/120 developed 2940 kW (4,000 hp) at 125 rpm and gave the ships a speed of 14, 5 kn. An average of 14.5 t of fuel was used per day. Three generators with 150 kW each were available to generate electricity . A total of six ships belonged to this class.

For almost 50 years they had been looking for an alternative to the previous wood-based material, the previous building material for lifeboats. Plastic turned out to be almost the ideal material to avoid the disadvantages of wood. The other alternative, metal lifeboats, had their advantages in terms of strength and resistance to fire. However, the service life did not meet the high demands. The glass fiber reinforced plastic was extensively tested by the See-Berufsgenossenschaft and by Germanischer Lloyd , and the testing of the GRP boat on the liner Spreestein went extremely well under the supervision of these companies.
