Launched this year, Bredero Shaw’s SureBond 100 coating system uses functionalised PE to simplify coating structure while offering improved mechanical and fi eld joint performance. Cedric Oudinot explains more
Functionalised approach
to pipeline protection
Energy markets and the energy transportation sector are under constant change. Global forecasts show a fast growing energy demand over the next two decades, primarily from non-OECD countries, which will be met by tapping increasingly challenging and remote fi eld developments. Energy demand and supply centres are becoming increasingly distant from each other. As a result, hydrocarbon transportation will play a critical role in the energy value chain. Safe and reliable hydrocarbon transportation
requires high performance anti-corrosion coatings. Pipeline integrity specialist Bredero Shaw has devel- oped a new pipeline protection platform launched earlier this year under the SureBond name. The new system uses a functionalised polyolefi n topcoat resin that eliminates the need for an adhesive layer while providing enhanced real-world performance.
Global challenges The starting point for the project was to research the global view of the current challenges faced by pipeline operators, which was used to frame out the functional requirements. This fi rst step in the standard Bredero
Shaw technology development process typically reveals common clusters of requirements, spanning geogra- phies and historically-used coating types. It is well known in the pipeline industry that the quality of application of a coating has a dramatic impact on long term system performance so it is important to choose a reputable coating service company. For those that do, and who are satisfi ed with the current performance levels of existing pipeline anti-corrosion coating systems, the overwhelming feedback focused on the fi eld joint as a primary root cause of integrity concerns. Further improving the performance of the anti-cor-
rosion main line pipe coating system will have only a marginal impact on overall pipeline system perfor- mance when the weakest spot, which is known to be located around the fi eld joint, remains unaddressed. It was clear that development of a next generation
coating would have to not only exceed current perfor- mance levels as measured against specifi cations (temperature rating, impact, cathodic disbondment, bending, thermal cycling and the like) but also to help mitigate fi eld joint concerns.
