The Dutch ship, on the right side, is either " Neder Waal " or " Neder Weser " of Nederland Line ( Stoomvaart Maatschappij Nederland ). Both were ca. 12.500 dwt. and built in the Netherlands in 1959 and 1960.
In 1977 they were both renamed and prefixed with " Nedlloyd ", due to the merger of several Dutch shipping companies, among them Nederland Line, which had occured already in 1970. Both ships were demolished in 1983 and 1984.
Your photo is probably from very shortly after this merger - due to the Nedlloyd funnel and the Nederland Line logo still to be seen on her bow.
