The Petrolea was an oil tanker owned by the Swedish entrepreneur Ludvig Nobel , which started operating in 1886. Together with the Glückauf , which was built at the same time , it is considered to be the world's first sea-going oil tanker of a modern design.
history
Although the Petrolea has remained relatively unknown compared to the Glückauf , its construction created an outstanding technical basis for the construction of sea-going oil tankers of modern design. The plans for the construction of the Petrolea were drawn up as early as 1884 or earlier by the senior Swedish shipbuilding engineer of the Motala shipyard S. Alquist. In the summer of 1884, Alquist, who has relevant experience in construction discussed could produce modern inland tankers, with the senior naval architect of the British shipyard Armstrong & Mitchell in Low Walker, Newcastle on Tyne Colonel Henry F. Swan, to Lloyd's Register or Bureau Veritas as Classification society for the new type of ship .
Construction of the Petrolea began immediately after the contract was awarded on November 12, 1885. The delivery of the ship was agreed for the period between July 15 and August 15, 1886. It was not until November 25, 1885, shortly after construction of the Petrolea began , that the keel of the Glückauf of the tanker shipping company Wilhelm Anton Riedemann was stretched at the Armstrong & Mitchell shipyard. Since the construction of the Petrolea was delayed a little later, the Glückauf finally got going on July 13th, 1886, while the Petrolea did not start her maiden voyage until September 2nd, 1886 (according to Lloyd's Register of Shipping, she did not even start sailing until 1888) .
After Nobel's death, Petrolea was renamed Ludwig Nobel in his honor .
technology
Building on the experience with the inland tankers built previously, such as the Zoroaster or the Moses , the Motala shipyard built the sea-going Petrolea . Their tank holds, which were divided by five transverse bulkheads and a central longitudinal bulkhead, were divided into upper and lower compartments. The upper tanks had a semi-circular ceiling, the outer boundary of which did not extend to the outer skin. A conventionally arranged protective wooden deck was installed over the upper tanks. The lower tanks did not have a double bottom, but had a triangular longitudinal beam on each side. The three-quarters aft arranged superstructures were supplemented by a bridge amidships during the conversion.
