Caird & Company was a Scottish shipbuilding and engineering firm based in Greenock. The company was established in 1828 by John Caird when he received an order to re-engine Clyde paddle-tugs.[1]

John's relative James Tennant Caird joined the company in 1831, and after leaving to work for Randolph, Elder & Co in Glasgow, rejoined the family business for good in 1838.

A year after the death of Robert Caird, the company was sold to Harland & Wolff Ltd in 1916 for £432,493. The firm continued trading as a separate enterprise, with Arthur and Patrick Caird on the board, until 1922. The Arthur Street engine works was sold to John G. Kincaid & Company in 1919.

In the early years Caird & Co were responsible for fitting (or re-fitting) steam engines in ships. An example of this is the Glasgow fitted with a side-lever engine by Caird & Co in 1828 for G & J Burns.[2] This being an engine running on only 5psi steam pressure, as was common at the time (the steam condenser created a vacuum so the effective pressure acting on the piston was the difference between the boiler pressure and the condenser vacuum). Also in 1828 Caird & Co re-engined the paddle steamer Industry (built in 1814 by William Fyfe of Fairlie), replacing the original single cylinder engine rated at 10 hp with a Caird single cylinder engine rated at 14 hp.

In 1845 details and drawings of Caird engines fitted in four West India Mail-Packets were published,[3] these being the "Clyde", "Tay", "Tweed" and "Teviot". These were also side-lever engines, with two cylinders of diameter of 74.5in and stroke of 90in, driving 30 ft paddle-wheels, running at 15rpm. These mail packets were operated by the Royal Mail Steam Packet Company. Collated records of ships built on the Clyde[4] suggest that Caird contracted out the building of the wooden hulls for these mail packets.

Other ships fitted with engines by Caird include :

Following this Caird fitted engines to a significant number of screw-steamers built by other companies (i.e. propellor driven) particularly those built by Denny of Dumbarton up until 1851, and other ship builders until 1863.[4]
