The Chemgas Terminal flag uses green in place of the blue areas. The lower-case chemgas name moves right into the area of the lower green triangle, with green TERMINAL below. An actual 150 × 220 cm flag appeared in a German eBay offer ending 25 June 2007. It was thought probably no longer in use.
Chemgas Terminal at Vlissingen became Vopak Terminal after takeover, possibly in connection with the 2003 shipping-company transaction. That connection is not established.
