Coiled tubing was first developed during World War II as a part of Project PLUTO.
PLUTO stands for PipeLine Under The Ocean. To support the landing of allied troops in Normandy it was necessary to provide sufficient amounts of fuel for the front in France. There had to be some supply from England and it seemed too dangerous to transport the required amount of fuel by tanker. Besides, there were initially no harbors to offload.
What was needed was a pipeline under the channel from England to France.
The pipeline had to be laid in a single night during the hours of darkness and this
was impossible using standard pipeline technology.
The solution that was proposed and developed was coiled tubing: a continuous
string of tubing, spooled onto a drum and unspooled across the English Channel.
By the end of WWII, a total of 23 pipelines had been laid across the English
Channel, supplying fuel for the allied forces. Seventeen pipelines were 30 miles
long and six pipelines were 70 miles long.
