When Diamantis J. Pateras died in 1951, the six brothers – John, Panagos, Pandelis, Stephanos, Costas & Nicolas – set up their own Company “DIAMANTIS PATERAS LTD.” in London to honour their father.
Two years after its inception, the Group’s first New Building of 10,000 DWT was ordered from a British Yard and was followed by two 12,800 DWT bulkers, “M/S KALLIOPI PATERAS” & “M/S DIAMANTIS PATERAS” and a 19,000 DWT tanker, the “PACIFICATOR”, all ordered in Kiel, Germany.
In 1958 further expansion in New York took place with the creation of NAUTILUS PETROLEUM CARRIERS CORPORATION owner/operator of a San Francisco built crude oil carrier, “M/T SISTER KATINGO”, 33,500 DWT.
