PLUTO Pipeline

The words

1. Bambi

   Bambi linked the Isle of Wight with the Cherbourg area. Leaks and damaged lines limited its usefulness, and it closed as the focus shifted to the Dumbo crossing.

2. Boulogne

   Boulogne’s sea terminal had to connect with inland transport. Naval work there remained dangerous: the tug Danube V detonated a mine while weighing anchor, injuring crew members.

3. Cherbourg

   Capturing and clearing Cherbourg was necessary before the first cross-Channel lines could be laid. The port’s readiness helped determine when the Bambi route could begin.

4. Conundrum

   Conundrums were floating drums that carried coils of steel HAMEL pipe. Tugs towed them across the water as the drums turned, paying out pipe onto the seabed.

5. Cross-Channel

   Before laying pipes to France, engineers tested a sea crossing from Swansea to Watermouth Bay. The Bristol Channel trials helped develop the methods later used across the English Channel.

6. D-Day

   D-Day was June 6, 1944. PLUTO did not supply that day’s landings: pumping through the cross-Channel lines began months later, after the Normandy campaign.

7. Dumbo

   Dumbo shifted the crossing to Dungeness and Boulogne. The shorter route delivered fuel later in the campaign, as Allied forces advanced farther across France.

8. Hais

   HAIS combined a lead pipe with protective outer layers, drawing on submarine-cable techniques. Its name joined Hartley, Anglo-Iranian and Siemens, contributors to the development work.

   Did you know?

   One surviving HAIS pipe section was turned into an ashtray, with a metal dish at the top and felt underneath.

9. Hamble

   The Hamble was the English base for coastal tankers supplying Port-en-Bessin. Their deliveries were a separate part of the fuel effort from PLUTO’s undersea crossings.

10. Hamel

    HAMEL was the steel alternative to the lead-cored HAIS pipe. Its name combined Hammick and Ellis, the engineers associated with developing this other type of PLUTO line.

11. Petrol

    Gasoline; a British English term.

    PLUTO’s petrol was fuel for the advancing armies. Pumping continued into July 1945, when the European war had ended and tankers were needed for the Far East.

12. Pipeline

    The seabed pipes linked Britain’s existing fuel network with new land pipelines in France. Fuel still had to move onward from the coastal terminals toward advancing Allied units.

13. PLUTO

    PLUTO stood for Pipe Line Under the Ocean. Research began in 1942 as planners sought a way to send fuel from Britain to France beneath the sea.

14. Sandown

    Sandown and Shanklin formed separate pumping sites on the Isle of Wight. Their installations connected the island’s overland fuel routes with the first cross-Channel pipeline system.

15. Undersea

    Undersea pipes had to withstand pressure from within and the water outside. They also faced damage from anchors, so a laid line still needed testing and repair.
