AllAfrica.com reports that one of Mozambique's few dredging vessels, Rovuma (former GOA), sank on Saturday in the port of Beira, Mozambique. The report said there was no loss of life, and the port authority said the stricken dredger posed no threat to maritime safety. The causes of the accident are not yet known, but the vessel's owner, the state-owned dredging company Emodraga, suspects it may have hit a hidden wreck. Rovuma is 45 years old, and arrived in Mozambique in the early 1970s, before the country's independence, and has been operating in Beira since 2000. In 1975 (then named 'GOA' and managed by the Dutch concern "Breejenbout" for the Mocambiquan dredging department "Emodraga") the dredge was sabotaged and sank alongside the quay in Lourenco Marques, starboard side down. After many days of negotiations South African Diving Services based in Durban, managed to secure the contract to refloat the vessel. As there was no salvage equipment locally available all equipment was mobilized from Durban. Vessel was successfully refloated and after the water protraction treatment had been completed, it was handed back to her owners "Emodraga". source: AllAfrica.com, Daily Shipping Newsletter
