The blue flag has a white RN logo and a wavy line. The company website also shows it in banner form.
Photographs of the hopper dredger Thor R show the funnel and a logo panel on the superstructure. In a starboard view the funnel, positioned to port, presents a plain blue side. A flag photographed in June 2011 is lighter blue than the funnel, closer to the website rendering. Gefion R on 16 December 2013 provides a clear funnel view. The funnel shade varies between photographs: Brage R at Newcastle on 19 August 2011 appears dark blue in dull light.
