The Immingham oil terminal is the main crude oil importing terminal serving the two giant refineries recently built on the south bank of the River Humber near lmmingham. These refineries, the Lindsey and the Continental oil refineries, represent some £80M investment. Early in 1969 it became apparent that in order to berth the large tankers that were anticipated, radically different berthing structures would be required quickly to meet projected finishing schedules for the refineries which would otherwise have to use the already out-dated and heavily used eastern jetties outside Immingham Dock.
The consulting company, GEM of Paris, already experienced in the design problems of heavy marine structures, were asked to advise on a solution to the problem. Their suggestion of structurally independent flexible berthing dolphins of the tubular type was accepted and an order placed with them for the design and fabrication of these tubes and structures.
