Protea is a specialist hydrographicsurvey vessel, although its equipment has been used in search and rescue operations using Protea's shallow water route survey system (SWRSS).[2] She is the only ship in the South African Navy that is painted white, denoting that she is not a warship.[2] Her hull is strengthened for navigation in ice and she is fitted with a transverse bow thruster unit, for increased manoeuvrability in harbour.[1]
In 1978 Protea took part in an international krill research project, becoming the first South African Navy vessel to round Cape Horn. She also acted as the guardship for the 1976 and 1979 Transatlantic Yacht races.[6]
She remained active in the post-apartheid navy and as late as February 2023 was reported to be participating in joint South African-Russian-Chinese exercises which involved the frigate Admiral Gorshkov and tanker Kama from the Russian Navy[7] along with the destroyer Huainan, the frigate Rizhao and the support ship Kekexilihu from the Chinese Navy, as well as other units from the South African Navy including the frigate Mendi.[8]
