A small device squeezes through a hundred kilometers of oil pipeline that twists and turns beneath the sea.
When the ‘pig’ returns it has recorded data about every centimeter, which Raven’s Point software will analyze and display in three dimensions.
I did this work for Pipelines2data in Aberdeen ( http://pipelines2data.com/ ) nearly three years ago. The software has been used a number of times since to plot pipelines, including some gas trunk lines in Texas.
