Concrete coating for marine pipelines

M. Braestrup, Rambøll, Denmark 

A significant, but fairly unnoticed, use of structural concrete is as weight coating to ensure sufficient negative buoyancy, as well as mechanical protection, of submarine pipelines, primarily for the transportation of oil and gas. After a brief introduction to marine pipeline technology the paper describes the design, application and testing of concrete coatings. Finally, the enhancement of pipeline installation stresses due to the greater flexibility of the uncoated construction joints is discussed.
