[2] Operated by the E. R. Management Company of Liverpool on behalf of the Ministry of War Transport,[4] Ocean Vigour was employed on convoys across the Atlantic and into the Mediterranean in 1942-1943,[5][6][7] and between June and August 1944 she is recorded on sailing on seven convoys between the English port of Southend and the Baie de la Seine on the northern coast of France.

[8] Under the designation HMT Ocean Vigour the ship was operating the eastern Mediterranean, employed in transporting illegal Jewish immigrants to detention camps in Cyprus.

[10] The 4,515 immigrants were transferred into three British ships, Runnymede Park, Empire Rival and Ocean Vigour, which sailed for Port-de-Bouc, France.

However most of the immigrants refused to leave the ship, and eventually they sailed for Hamburg, Germany,[11] where on 8 September, the 1,464 immigrants aboard Ocean Vigour were forcibly disembarked[12] by military police and soldiers equipped with truncheons and tear gas, and taken to internment camps in Lübeck.

Finally in 1957 the ship was sold to the Italian company Corrado Società Anonima di Navigazione of Genoa, who operated her under the name Confidenza until 1967, when she was scrapped in La Spezia.
