Othher pollution incidents included the 1990-built 285,000 dwt Singaporean VLCC Napa that interrupted its voyage to the US Gulf when hull problems left an oily sheen on the water. Oil had leaked from a crack in the shell plating in 4 starboard cargo tank caused by the heavy swell in the winter seas off South Africa. The leak was stopped by increasing the ullage in the affected tank to achieve hydrostatic balance.

The Singapore flagged VLCC Napa is waiting off the coast of Madagascar to tranship its 275,000 tonne cargo of crude oil to another ship, following the discovery of a crack in the vessel's hull. According to the vessel's manager, Worldwide, the 285,640 dwt tanker was en route to the Gulf of Mexico from the Middle East Gulf when the ship's crew spotted a sheen of oil leaking from the vessel. The leak was traced to a crack in the side shell plating of the No 4 starboard cargo tank and is thought to have been caused by "a heavy swell in the winter seas off Southern Africa". Worldwide confirmed that the leak had been stopped and the Napa was not disabled in any way. However, the vessel will not complete its voyage and will instead proceed "to a suitable port for inspection and repairs". Worldwide chief operating officer Billy Chiu explained: "In consultation with charterers, we have decided to curtail the voyage and transship the cargo to another vessel."

Almost always once you get a hull crack leak stopped, you keep going and mention the problem to nobody. Something must have been badly wrong structurally to force Worldwide to face the costs and publicity of a transhippment.
