The Ottoman Turks used the word ''liman'' (from Greek ''limēn'') to refer to harbours in general, but in the 15th century they also adopted and increasingly began to use the term ''tersane'' (often misinterpreted as ''tershane'', incorporating the term ''hane'', "house") from Italian ''darsena'', "shipyard"—likewise the origin of the English "

(1571), the Imperial Arsenal was extensively renovated, with eight new dockyards built inland, surrounding the royal garden (''has bahçe''). By the end of the 16th century, two large storehouses had been built: the Kurşunlu storehouse, for shipbuilding and rigging materials and other ship equipment, and a storehouse for timber.
By the mid-17th century, the number of docks had risen to 140. At its peak in the 16th and 17th centuries, the Imperial Arsenal was a major industrial concern, "with dry docks, shipyards, storehouses, a spinning mill for making cordage, and iron foundries (for making anchors), supplemented by public buildings, including a mosque, fountains, a hospital, and a prison, all clustered in the Golden Horn". Nevertheless, the 17th century saw decline: in 1601 the shipyard had 3524 employees but this number steadily fell, reaching 726 in 1700. During this period an increasing amount of work was done by other shipyards.
This was facilitated by the fact that galleys, which formed the bulk of the Ottoman navy until the late 17th century, could be built by any skilled shipwright, and that consequently they were frequently built in the provinces at coastal or river sites, and only brought to the Imperial Arsenal for outfitting.

(late 17th–mid-19th centuries), each ship's superintendent, treasurer and scribe were also considered as part of the officer corps, while "captains, mariners, overseers, messengers, shipwrights, caulkers, oar makers, ironsmiths, repairmen, spoolers, towmen, grenade-makers, guards, and retired personnel" comprised the numerous "common folk" of the Arsenal.
As part of Selim III's military reforms, the ''tersane emini'' was replaced in 1804 by the
Ministry of Naval Affairs (''Umur-ı Bahriye Nezareti''), while a modern financial department and treasury were created for the Arsenal in the next year. In 1845, the separate Ministry of the Imperial Arsenal (''Tersane-i Amire Nezareti'') was created.
