Abstract

© 2015 Elsevier Ltd. All rights reserved.Composite repairs are emerging as a viable and often preferred alternative to metallic repairs in the oil and gas industry. The use of composite presents key advantages over metal, including reduced weight, smaller relative density with water and greater corrosion resistance. This chapter reviews current and emerging methods for composite repairs of pipelines, along with repair codes, and presents in-depth discussions on two different repair solutions: clamp and overwrap. It is shown that these composite repairs allow rehabilitation of wall thinning and through-wall damage above water, in the splash zone and subsea, over a range of conditions.
