V27 is divided by a slanting line: green and blue horizontal stripes at the hoist and a white fly bearing the square company logo. The white-over-red hoist-diagonal element represents Utrecht’s city flag. Jarig Bakker’s image of 17 November 2005 follows Brown 1995. Rosanoski notes a possible small alteration to the earlier ACZ flag.
The panel on V164’s white oblong appears to show V15, but could be V27: the detail in the white part of the source drawing is effectively absent.
V15’s funnel is confirmed by Volvox Iberia; Josef Nüsse supplies the table flag. Mitchell records the flag panel as resulting from a 1991 ACZ–Van Oord amalgamation, differing from the 1990 history, but does not specify its use.
The later flag is white, with a large orange triangle at the fly facing a blue wave from the hoist. Actual flags also carry the company name in white. Photographs of Saga and Pelican initially left a possible blue border uncertain; Volvox Scaldia later showed that the border was not part of the design. V166’s funnel top is dark blue, while other photographs appear black as V167, although some may show a very dark blue. A close-up of Volvox Scaldia appears black; Pelican’s close-up more clearly shows dark blue. V167 also comes from Volvox Scaldia and Anna photographs. Bakker supplied the FOTW flag image in May 2006, and Nüsse provides a later table flag.
V165’s funnel comes from Mitchell; the document supplies no separate design description.
V312 comes from a port-side photograph of Jan Leeghwater on 25 June 2013.
Lloyd’s traces ACZ from Aanemers Combinatie Zinkwerken B.V. in 1973 to ACZ Marine Contractors in 1983 and then, in 1990, Dredging VO2 International and Van Oord ACZ. Rosanoski disputes that sequence because Dredging VO2 is already recorded in 1973–1974: he considers it acquired in 1990 and renamed Van Oord ACZ Material B.V. in 1993. Van Oord N.V. resulted from the Ballast Ham Baggeren and Van Oord ACZ merger effective 19 December 2003, although the overview gives 2004.
Later operating companies included Van Oord Nederland at Gorinchem and Van Oord Ship Management at Rotterdam, Ballast Ham Dredging DO Brasil, Ballast Nedam Bagger-en Exploitatiemaatschappij, Brewaba Wasserbaugesellschaft Bremen, Exploitatie Maatschappij Maritiem, Nederlandsche Overzee Baggermaatschappij and Van Oord India. Brewaba was formed in 2002, NOB in 1992 and the Mumbai company in 2006. Dredging V.O. 2 was a joint venture with Van Ommeren.
