Rangers in wet suits have been searching for oil-tarred penguins in shallow water around St Croix Island off the South African coast as a refuelling spill highlights conservationists’ fears over pollution. Experts said an unknown number of penguins had been affected on the rocky, uninhabited island, which is home to the largest breeding colony of endangered African penguins in the world. A Liberian-flagged ship spewed between 200 and 400 litres of oil into the sea off Port Elizabeth city during “bunkering” re-fuelling – the process of filling a ship with fuel from another vessel. The small-scale leakage from the bulk carrier MV Chrysanthi vessel at dawn on Saturday was the second oil spill in the environmentally-sensitive area in three years. “This is exactly the concern with offshore ‘bunkering’ that we have been voicing concerns about,” Stacey Webb, of the Southern African Foundation for the Conservation of Coastal Birds (SANCCOB) charity, told AFP. “The danger is not over yet. Penguins forage up to 100 kilometres (60 miles) away from the islands (St Croix Island and Bird Island) so they could run into the spill out at sea.” About 20 penguins covered in black sludge have been rescued by national parks rangers so far.
The weekend spill follows one in August 2016 when about 100 birds were affected by a smaller “bunkering” spill. “Bunkering” only started in Ngqura port, part of Algoa Bay, in 2016, with the shipping industry promoting it as an economic boost for the area.
