The ship drew worldwide attention in 1988 for transporting the mine-damaged USS Samuel B. Roberts from Dubai to Newport, Rhode Island.

When loading its mammoth burdens, the ship took thousands of tons of water into ballast tanks, submerging its cargo deck.

Her most famous job was the July 1988 haulage of the U.S. Navy's USS Samuel B. Roberts from Dubai to Newport, Rhode Island, after the guided missile frigate struck a mine in the Persian Gulf on 14 April 1988.

On 6 December 2006, Mighty Servant 3 sank in 62 metres (203 ft) of water near the port of Luanda, Angola, while offloading the drilling platform Aleutian Key.

The ship was en route from Singapore to Cabinda, Angola, bearing the North Nemba Topsides 8,790-ton offshore production module.
