Document - F. Schichau (Schichau-Werke, Elbing) - 1906 Schichau-Werke Naval Engineering Letter to Ottoman Vice Admiral Ahmed Pasha – Shipbuilding / - 1906

Offered here is an exceptionally rare original naval engineering correspondence, dated 1 September 1906, sent by F. Schichau (Schichau-Werke, Elbing), the legendary German shipbuilding and armaments manufacturer, to His Excellency Vice Admiral Ahmed Pasha, Chief Engineer of the Ottoman Imperial Navy (1st Naval Arsenal, Constantinople).

This document concerns a technical safety assessment related to the riveting strength, plate thickness, and structural integrity of naval construction materials. It also references a telegram sent to Genova, confirming insufficient riveting strength and recommending double-joint riveting for improved safety. Such explicit engineering details are almost never found in surviving Ottoman naval correspondence.

Schichau-Werke was responsible for building a large portion of late-19th and early-20th century torpedo boats, destroyers and naval machinery for major world navies, including the Ottoman Empire.
Letters addressed directly to Vice Admiral Ahmed Pasha (M.I.Mech.E.), one of the key engineering authorities of the Ottoman fleet, are exceptionally scarce and historically significant.
