In the late 1960s, mobile offshore drilling units (MODUs), such as the one shown on this 1:240 scale model of the Staflo mobile oil rig, began to be built for the North Sea. Staflo is a semi-submersible exploration platform built at Haverton Hill on Tees in 1967. Until 1975 the rig was used by Shell Expro. In 1971 it was credited with discovering the Auk and Brent oil fields, both over 100 miles off the coast of Scotland. Between 1976 and 1982 the rig operated off Angola and was then converted to a floating production facility for use off Brazil. This model representing the rig's position in the North Sea was donated to the Science Museum by the late F. J. Chate OBE, former director of Northern Operations, Shell Expro.
