Fibre composites for high pressure pipeline repairs, in-air and subsea: an overview [PDF]

, 2012
In 2001 it was reported that in North America alone, corrosion to the Oil & Gas pipeline distribution network cost approximately $2-3.3 billion per annum with 10% of that cost being associated with actual failure of the pipeline.
