Archdecker
The Archdecker was a type of bulk cargo ship that originated in Britain in the early 20th century . The name is derived from the design of the ship's hull with a lateral arch-shaped bulge of the outer skin that extends over the entire length of the hold. The bulge increases the strength of the longitudinal structure of the ship's hull, which saves reinforcing fixtures in the holds. The ships powered by a steam engine were mostly used as colliers in the coal industry, as the construction principle allowed self-trimming ships with large hatches.
The design of the new type of ship was introduced in 1910 by the naval engineers Ayre and Maxwell Ballard. The first ship of the type was the Edenor of the Swedish shipping company A / B Edenor , which was delivered in May 1911 after lengthy delays from Osbourne, Graham shipyard . From 1911, the ship type was also built by the Blyth Shipbuilding & Dry Docks Company . Their first ship of this type was the 1912 Sheaf Arrow of the shipping company WA Souter from Newcastle. The shipyard built a total of seven ships of the type. A total of 28 Ayre-Ballard-Arch deck steamers were built. The interest of the shipping companies in this type continued until the Second World War.
