 While "Vale Beijing" delayed the loading of only 750,000 tons of iron ore, on 11 November 1994 "Trade Daring", a 145,000 DWT ore-bulk-oil carrier, broke in two at the same location due to incorrect loading, blocking the deepwater pier of Ponta da Madeira for more than six weeks before the wreck was removed and scuttled offshore.After the incident, the China Shipowners' Association (CSA) questioned the safety of the 400,000-ton ore carriers commissioned by Vale.CSA was particularly concerned about the ability of the newly built ships to withstand various sea conditions and the pollution resulting from fuel oil leaks in case of structural damage — each "Valemax" ship can carry around 10,000 tons of fuel oil.
