She was renamed ROVUMA, after a river in East Africa and the boundary between Tanzania and Mozambique.
1975 She was sabotaged and sank on her starboard side alongside the quay in Lorenco Marques (Maputo). At that time she was managed by the Dutch company Breejenbout, and owned by Emodraga.
She was first righted and then refloated by the South African Diving Services from Durban.
There was not any salvage equipment locally; all equipment to salvage the dredger was coming from Durban.
She was successfully salvaged and after the water protraction treatment had been completed, she was handed back to Emodraga

June 2007 withdrawn after arrival of a new dredger from Japan, the ALCANTARA SANTOS.
21 April 2007 hit a submerged object and sank in position 19 49S 34 52E. Mozambique dredging vessel M/V Rovuma -- sank on Apr 21 in the central port of Beira. There was no loss of life, and the port authorities, cited by Mozambican Television, 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. M/V Rovuma is 45 years old, while the average life span of a dredger is between 15 & 20 years. It arrived in Mozambique in the early 1970s, but this is not the first time M/V Rovuma has sunk. She 1st went down in 1975, in Maputo port. M/V Rovuma has just 3 more months of life left. It was due to be scrapped in July, when a new dredging vessel should arrive from Japan.
