Part-sectioned model (scale 1:64). This turbine steamer was built by Cammell Laird to the order of Shell Tankers Ltd, of London, for the transport of crude oil in bulk. Her hull contained eleven main oil tanks, each subdivided by longitudinal bulkheads into three compartments. The increased subdivision of such vesels is esential, to avoid too great a free surface of oil which would endanger their stability, to accomodate oils of various densities, and to facilitate trimming of the ship. The 'Zenatia' was used to transport crude oil from the Persian Gulf to refineries in Britain. In 1966 she was lengthened, widened and deepened at a Japanese shipyard, to be 842 ft long and 69,956 tons deadweight.
