Loughran shows three blue wavy funnel lines, matching the Harrison emblem. Marinart confirms them; Stirling Dee’s September 1991 photograph also supports the design, although its aged colours make the lines look rusty red rather than blue.
Mitchell describes a Harrison-type funnel with the panel or shield represented as the swallow-tailed flag. The museum flag, dated 1986, measures 1,854.2 × 1,193.8 mm. Its wavy lines are said to represent the River Clyde, and the design resembles that of associated Harrisons (Clyde).
The offshore-supply operator began in 1974 as Stirling Shipping Co. and became Stirling Offshore in 1995. Harrisons initially operated part of its fleet and later managed the whole fleet. Seacor Marine (International) is listed as owner from 2002.
