Subsea pipelines are externally concrete coated to provide vertical and lateral stability. The loss of concrete can lead to floatation or lateral movement on the seabed. If seabed is hard/rocky, then lateral rubbing may lead to wall thinning at 6 o'clock and can result in a leak or flattening at the bottom affecting ovality. This paper presents...

Subsea pipelines such as flowlines, trunklines etc. are an integral part of all offshore field developments. Sour service conditions as encountered by production pipelines of gas fields require CRA clad pipe due to high risk of localized corrosion initiation and penetration rate in carbon steel. This paper presents an innovative approach to...
